Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Not that I have the money at the moment, job hunting after quitting a decent paying but brutal on the conscience sales job, but I have been tossing around the idea of changing out my stock exhaust, at some point. My Boxster S had an awesome sounding Fabspeed system on it, and the burbles and pops when you let off the throttle were glorious. The howling at high revs was downright arrousing. But alas my 996 has a stock system, and I miss the burbles and pops and other sexy noises. Though the big, big, thing I like about the mostly quiet stock setup, when setting off from a stop with the windows down I hear nothing but a beautiful flat six mechanical symphony, it is raw and simple, and I do love it. Though most of the rest of the time, unless I'm at WOT and about four grand, it's just really quite quiet. I guess my question is, have you done an aftermarket exhaust and how do you feel about it, do you miss the stock setup, or do you have it stock and wish it weren't?

POST 2Original post

My other car has a loud aftermarket exhaust, which makes me really appreciate how quiet the 996 is for driving around every day but still sounding good when you step on it. I'm really curious to hear a Fister exhaust mod though, since it's relatively affordable, supposedly reasonable in volume, and everyone here that I've heard that has one has absolutely raved about it.

POST 3Original post

don't settle adapt a 997 GT3 center outlet muffler onto the 996

I've heard a lot of good things about it as well, though I'd like to hear it in person and preferably from the inside of the car as well. I don't want to sound like some kid in a civic that put a fart can on the car, but like I said before the Fabspeed setup added a nice presence to the car, especially when going through tunnels or next to some walls

POST 5Original post

ddont waste alot on expensive exhaust, all they are is tubes that air goes through. look at maxspeed, agency power, check others on ebay. you should get headers, mufflers, cats complete SS for 2500-3500 and great sound and performance

POST 6Original post

Tubi adds like 178 bhp, weight relief is near 300 lbs j/k,....expensive but worth it

POST 7Original post

Agree with above...on the 996 our full package with headers, X-Pipe w/ cats and sport mufflers sounds absolutely fantastic. It all just went on year end sale today, too!

POST 8Original post

Now's the time bro. You quit a job that was bumming you out, and it's time to let the lion roar. The hard part was quitting that job. The exhaust thing is a no brainer. I'm in the 997 house, but 2nd 3rd and 4th any support for the Fister/Gundo option. For a couple hundred bucks at most, it's done, the car rumbles, burbles and pops as you like. If you don't like it? (not going to happen) You just swap your mufflers with someone else on here who has the OG cans on their car. It's easy. But you won't want to swap. Nobody ever wants to go back. And since you're between gigs, you gotta treat yourself to keep motivated. The gundo carrot. The Fister reward. Remind yourself the answer to the age-old question and follow through. Q: Exhaust or Not? A: ALWAYS EXHAUST! there's a ton of videos out there - but just listen: You Tube You Tube It's a no brainer man. You got this. Post a clip when you get it done. You can thank the entire rennlist community later. and good luck finding the new gig. I'm on the hunt myself, so I hear you on the dolla-bills front. - Dan

POST 9Original post

In my cabriolet the Gundo hack is just about perfect. For a coupe the Fister will probably be a better fit as it's just a bit louder. Both sound great are are really inexpensive to do. Replacement systems can be great for performance and weight savings but are a different price bracket altogether.

POST 10Original post

I have a Fister on my cab and it sounds amazing! I will never go back to stock. YouTube videos cannot do justice. I purchased mine after reading a ton of awesome reviews and attempting to listen to sound clips on the web. You cannot go wrong for the money.

POST 12Original post

I run Afterhours Exhaust.... For weight savings primarily and yes it is loud... can get obnoxious in 3rd gear between 48 and 53 MPH... but I wouldn't change it back to stock ever. I love the noise. And will eventually add an X pipe to help the system become a little higher pitched. Right now it is very deep/throaty but would like a little more Exotic sound. You can also run an X pipe on stock mufflers and may be able to achieve the sound you want. You Tube

POST 13Original post

Last Summer I had my local muffler guy mod my OE cans with the PSE hack. Noticeably louder but still not nearly enough grunt for me. After six months the PSE muffs seem almost like the stock ones again. Bummer. This Summer I'll take them off, store them, and go through the exercise again with another pair of OE cans I bought on eBay - but this time with the Gundo hack which will be louder. If the Gundo's disappoint I'll take my PSEs and + Gundo and try that. That's the plan anyway. Moral of the story (in my view) is that nothing fits better back there than the factory pieces. Some of the aftermarket stuff is real crap from a fitment perspective. Be careful not to trade for rattles in your quest for sound.

POST 14Original post

I know EVERYONE goes on and on about the Fister, so one more probably isn't useful - but as an extra data point: My wife loves the sound; my neighbors are begrudgingly complimentary (meaning yes, it's a little loud, but it sounds awesome); the crazy German lady who lives at the end of my street tries to get me to wind it up every time I pass her house, total strangers have told me that my car "sounds the way a Porsh oughta," and my dog - according to my wife and the dog sitter - knows I'm nearly home when I'm about half a mile away. The Fister is the ONLY mod I've ever done to my 996 that I have never second-guessed or wound up uninstalling. Note that the only thing currently considered a "Fister" mod is the coupling of the inlet and outlet pipes with a crossover pipe to allow some exhaust to bypass the muffler entirely. The "old Gundo" / PSE hack, which involves adding a new opening to the muffler and connecting that to the outlet pipe, is almost always disappointing (based on watching these threads for the past 4 years)... Warning: You will turn into one of those hooligans who needs to blip the throttle in every tunnel, overpass, and parking garage. Forever.

POST 15Original post

FastM96, Nothing wrong with your plan above. Or you can just skip it all and go with a proven winner for not much $$$....FISTERs!

POST 16Original post

Quotes source post: 13825217

Sure. I know there is some debate about this, but I consider the PSE hack to be opening the top muffler hole and adding a pipe between that hole and the outlet pipe, which sort of mimics the OE Porsche Sport Exhaust option. I consider Gundo to be the addition of a crossover pipe between the inlet and outlet pipes, aka Fister, and that's the track I'm on with my local shop come this Summer except without the Cermachrome finish.

POST 17Original post

Quotes source post: 13825264

Another satisfied Fister customer. BTW Gundo is not the same as Fister but some folks refer to the mod as such. IIRC Gundo is the "PSE hack" you described. Search and you can find good pictures of both and the difference is obvious.

POST 19Original post

I'm running Fabspeed headers and mufflers with a Speedtech catless X-pipe. I would not go back to stock if you paid me twice what was spent on these parts! I absolutely love the sound of it and it REALLY woke up the car when I added the catless x-pipe.

POST 20Original post

Gonna repeat simply for emphasis- Fister D. I've never received so many compliments on a car's sound.

POST 21Original post

Quotes source post: 13823014

Couple points on this video: 1. Car has factory sports exhaust (XLF) 2. This is SpeedTech's Catless X-pipe. 3. Second cold start of the year, coming out of winter storage, so I kept off the revs (no more than a 2500 rpm blip) 4. Car is loud AF above 5k in a tunnel Speedtech was great to work with, and $1,000 CAD cheaper than Fabspeed for the same chunk of stainless. Fitment of that X-pipe was better than my Sharkwerks crossover pipe on my 997.2.

It is excellent to hear that you've been so happy with our system in the past on your Boxster! I would love to get you setup with new Fabspeed system for you 996, and forum members do get a product discount as well so drop me a line and let me know what you'd like to start with. Personally I like ditching the factory cats right off the bat, it is the biggest restriction point on the car To date the best street combination I have ever heard on the 996/997.1 was our headers, catbypass x-pipe, and our maxflo mufflers. Glorious on throttle and minimal/no resonance off throttle just cruising around. I can imagine how much fun you have blasting around in yours! Here are some videos of that setup on a good friend of mine's 996 https://www.youtube.com/watch?v=jGaDXMXMlK8 https://www.youtube.com/watch?v=srIojrgZrRI And then we gundo hacked the maxflos for the track...didn't think it could get any better but I might have been wrong haha. https://www.youtube.com/watch?v=9oyzAys5QaI

Yep, definitely some lingering debate about this. Based on what I've seen online this is PSE: And this is Gundo (aka Fister): That's the info I have anyway. Would love to hear views to the contrary - I'm fairly new to the 996 game.

POST 26Original post

PSE is the legit version from Porsche that costs a bunch and weighs a bunch. Gundo developed the hack version that simulates PSE. Incidentally, Gundo later installed different aftermarket cans on his 911. Fister is the guy who sells the Fister mod. He does nice work.

Wow, testy with CAPITALIZATION. I never claimed they are the same - only a moron would claim that. BMW guys get a rap for a reason.

POST 28Original post

Here is one vote for Fabspeed. I've had these on for a long time, build quality is excellent, sound is awesome. I'll tell you what, I've run through the tunnel at the speedway and nothing comes close to sounding like them. I don't care about a power/HP debate, but the sound...ohhhh my goodness. So there, I don't think you would ever regret getting Fabspeed! For whatever it's worth...there ya go.

POST 29Original post

I had GUNDO's.... they are not satisfying, maybe increased 2-3 decibles... Don't waste the money going the gundo route... The only thing I could imagine making them sound OK is by adding a catless X pipe.

POST 30Original post

Quotes source post: 13828186

I agree with 5CHN3LL on this one. Fister is Fister and PSE without the on/off solenoid is Gundo. The Gundo hack is pretty much perfect on my cab with the top down but would probably be too quiet in a coupe for most people. Fister sounds more aggressive and is definitely louder but not too loud. Drone free and deliciously raspy. Sadly too loud for my wife in the cab. Had to choose between her and the exhaust so I guess we all now know who's whipped here....

POST 31Original post

Fister d hack: like $200 max at your local muffler shop and sounds SICK. Be sure to know the difference between gundo and fister and have them do the fister.

POST 32Original post

Is there anyone in the Chicago area that has done anyone of these exhaust mods and would be willing to get together? I have a bone stock 1999 996 C2 Cab bone stock. Too boring. I am interested in either Gundo or Fister, but likely not going to spend a lot to get a new exhaust. Sound is very personal from person to person. Just 2-3dB different is 50% louder or softer. What sounds good to one person doesn't sound good to another. What one person thinks it loud is too quite for another. I had a Harley with loud pipes and feel like I would never go back to something that loud. But the stock 911 bone stock is too quiet. I'm looking to make a change but only if the sound is just right, and the videos are great, but nothing is quite a good as hearing it in person. I'm on the Oak Park/River Forest, IL area, BTW. EDIT: If my Porsche sounded like this (my neighbor's Maserati), I'd spend more money: You Tube
