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.

34 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

POST 1 / ORIGINAL POSTEROriginal post

I have a 2002 996 and am confused on somethings I have been reading on the forums. I see people posting 996.2 what is that? What is a 3.4 can and 3.6 can. Is that the engine size? I am guessing I would be a 3.6 can. What is the correct way of doing the fister or Gundo mod? I see different pictures on the forums. 1. 2. 3. To me #2 and 3 look correct for a deeper voice. Which way would sound the best for a DD. Thanks Copper

POST 2Original post

996.2 aka 996 MK II cars were built between 2002 and 2005. They have a 3.6 engine, as opposed to the the 3.4 engine in the MK I cars built from 1999 to 2001. The bottom photo (#3) in your post looks like it is directly from Fister's website.

POST 3 / ORIGINAL POSTEROriginal post

OK understood. Picture - It appears to be the same mufflers on their web site but turned 180 degrees. Which way is correct? Is #1 an older mod or stage one instead of stage two? Thanks

POST 4Original post

Correct way is send them to Darin fot the FisterD PSE stage II mod

POST 5Original post

Quotes source post: 8437107

There are many ways to do this mod, and not any one is "correct". The first photo is what I would call the PSE Hack modification, where a pipe is welded in the same place that OEM PSE would go. It bypasses one chamber of the muffler. The Fister mod is a partial bypass of the entire muffler, not just one chamber. I've got Fister mufflers on my C4S, and I love them. I would highly recommend this route. You can also tell that #3 is a Fister muffler because they are ceramic coated, as offered by Fister. This mod is mostly cosmetic, although it does reduce radiated heat. I had it done to mine.

POST 6 / ORIGINAL POSTEROriginal post

I am looking at this route - Fister mod. I am just worried that I will get them in and hate them. Then I am out the stock mufflers. Do you know if you try them and dont like if yiou can return them? From what I have read no one returns them but I am sure someone put them on and hated them. Thanks John

POST 7Original post

Before I did the FisterD mod, I had so many questions ...so I called Darin and he walked me through options, prices and exchange of OE mufflers etc. They are hands down one of the all time best things you can do to make your water-pumper 996 so BETTER.

POST 9 / ORIGINAL POSTEROriginal post

I guess I will call them and ask them about the return policy. It would be a quick turn around.

POST 11Original post

+1 Fister! Copper I would be shocked, very shocked, if once you got your Fister's back and installed them that you would have any problems. Darin is awesome to work with and his work is superb! Having said that, I'm sure if you didn't like the sound, you could post them for sale in here and they would be gone. You could also most likely get a set of 3.6 cans, un-modified form with the future buyer or someone else. Really, I don't think you will have any issues with the Fister mod..then sound is music, sweet music! GL

POST 12 / ORIGINAL POSTEROriginal post

Thanks. I guess I will be ordering the fister!

POST 13Original post

Buy a set, send them out, if you like them sell your stock ones to next Rennlister. That is what many of us have done. Check for sale section. https://rennlist.com/forums/for-sale...d-muffler.html

POST 14 / ORIGINAL POSTEROriginal post

Quotes source post: 8437385

I Cannot see the ads area. copper, you do not have permission to access this page. Is that because I am a user and not a paid member yet?

POST 16Original post

Copper - I bought a set of used cans from a fellow Rennlister and sent them to Darin Fister. I did this for the reason you stated - what if I don't like the sound? Here is some advice from someone who made a few costly mistakes in this area: If you decide to buy another set for the modification, have the seller ship them directly to Darin. I had mine shipped to me and then sent them to Darin. That was $60 wasted. Darin will send you a modified pair and charge you a core deposit. You will get that money back when you send him your old mufflers. This way your car won't be idle while you're waiting for them to come in and you won't have to buy another set. You will love the sound and won't be putting your old mufflers back on. I have my old unmodded set and haven't decided if I'm going to sell them or hold onto them.

POST 17Original post

The only reason I can think one would not like an exhaust mod would be because it either drones or it's too loud....or too quiet. Fisters have no drone at all anywhere. With just the modified mufflers, it's pretty darn close to perfect soundwise...I just had to have it a little more louder so I added 200 cell cats and I can confidently say that it sounds darn good and have not plans to switch.

POST 18Original post

Quotes source post: 8437973

Did the cat upgrade make it noticeably louder? Amy drone? I've been considering going to Fabspeed cats to compliment my Fister mufflers.

POST 19Original post

Copper--if you're really worried, link up with someone in the Houston area who's running the Fisters in their 911 and listen for yourself. Then make your buying decision. Having said that, based on the huge number of positive posts on every P-car forum about the Fisters (and no negative ones that I've found), the likelihood of you being disappointed is very low. And, if you are, the $$ outlay is quite modest. Good luck.

POST 20Original post

I took off my MKII and put on MKI. I have a friend who custom builds hot rods. Will do the mod on a Saturday. The MKI makes the Pcar sound like a 79 Pinto. Need to get this done ASAP. Will post pics when done.

POST 21Original post

Quotes source post: 8438351

You'll notice it...but it's not that big much of a difference...still no drone...I'm not sure if/how the fabspeeds x design will sound different than mine...as I have the old separate style cats...

POST 22Original post

sorry - late to the party Copper - dont worry...as of yet I have never ever ever heard anyone say the FisterD's were anything but perfect. There may be the occational person who wants "more" but for a non-track build car they are perfect.... you want the MKII (aka 3.6 cans) they look pretty much exactly like the MKI's (3.4) but worth the effort to find them if you dont already have them... get the stage II. once on it will be very nice, then go thru a covered parking or tunnel at WOT, or let someone drive your car and listen from the outside... its more sound than you think because its outside....not droning in your cabin causing hearing loss to you... jusy pedestrians hope this helps

POST 23Original post

I had Fisters installed on my C4S last December. Dan sent me the cans after I paid and I sent mine after installation. I absolutely love the sound after my initial apprehension. No drone and after warmup; like stock until you put your foot in. At crusing speed, it is almost inaudible. I say "go for it".

POST 25Original post

Here is a video of how it will sound http://www.youtube.com/watch?v=WXVMvXNLva8

No, please, don't keep it a secret! Share it for others like me who also consider doing this mod!

POST 29Original post

Just had mine done yesterday by my exhaust guy. He used 2.25" pipe. It sounds great. Love it.

POST 30Original post

glad it worked out... in a while the sound even gets mellower and very sweet

POST 31Original post

Thank you Guys! It is now high up on my to-do list...

POST 32Original post

first thing you will ask when done,...... "What the ?!?!?! - Why The H&LL didnt it come like this from the factory!!"
