Only way for me to adjust these is to cut the oval tips right after the 90deg elbow and twist them and then weld them back on.

no sound clips will give you any idea how nice this really is...the only draw back (if there is one) is there is almost no noticable chance inside the cabin at cruise...but outside is a very nice change indeed!
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.

I have a Shelby GT 500 in the garage with straight pipes and love it but just did not work on the 996.
I love the heck out of these things. They are loud, but not as loud as I thought. Makes the engine sound so nice. Changed the fuel filter, plugs, and fresh oil change also. Next....need to change the brake fluid. This 996 has been very kind to me....also, no RMS leak either....
Not always a weekend car...and nope...had a Chevy LS1 with exhaust cutouts...so I know how to deal with them. Not near as loud as that....and I am only 40 so not that old. Muscle Car guy here....so I love to hear the engine. They actually are just a bit louder than the exhaust on my Durango 5.9 R/T. Pitch is a bit higher...but it puts me in the zone. I have no issues.
I understand these are not for everyone, but for me....perfect.
I found a set on Craigslist last year for $75
Even the seller talked me out of buying them!!!
I am glad I did not and kept my Fister Ds
But if the pipes are ok with you enjoy them as much as you can!
Mine lasted 50 miles on the car and then I had to remove them for being to loud. I am also in my 40's and all about the muscle cars. I have a Shelby GT 500 in the garage with straight pipes and love it but just did not work on the 996.
They arent that loud!! The thing that annoyed me was when I was driving in town below 3500rpm it was just too loud and obnoxious. On the other hand.....WOT sounds very nice.
I had a chance to hear in person a 996 with the bypass pipes....definitely too loud for me.
I will modify 3.4 cans (Fister partial bypass). I really like the sound (although have not heard in person, only sound clips).
no sound clips will give you any idea how nice this really is...the only draw back (if there is one) is there is almost no noticable chance inside the cabin at cruise...but outside is a very nice change indeed! if you forget, drive thru some covered areas (tunnels, parking, between buildings) with the windows open...always remind yourself how nice they sound outside while saving your hearing inside
We had someone show up to a local autocross with bypass pipes on his 911. Even the car guys plugged their ears when he'd go by. Which we don't do for the snowmobile engine cars, the Radical, Vettes, Shelby Cobras, etc. Way too loud.
OTOH, it's not as loud as some of the hillclimb cars I've heard running open headers. And my ears are still ringing from the F1 race I went to years ago....
They are definitely loud, but come on they aren't as loud as a Harley as long as you still have catalytic converters. I'll admit that they annoy me when driving around town, but on the highway they're not bad and anywhere you get to stay on the gas some, like an autocross, they are AMAZING. And I only have $75 ebay ones, not the pricey Fabspeed ones. I do have another car I usually drive to work and I admit that if the 996 were being driven every day I would put the stock mufflers back on.
I have already been "spoken to" by the police officers at the base gate though.
to be fair....I really am just being silly and I hope you enjoy them. I do know a couple people that swear they love em....I am just pokin at you and its meant in fun, not poor taste or trying to be mean...
just so we are clear....ya know
IT'S NOT THAT LOUD REALLY. HUH? I'M SHOUTING?
Oh, sorry.
I've been running my race car wide open. No cats, not mufflers. It's so loud, some racers even complain.
That's because your cobra and vette had a nice rumble to them. You need to drive it more, if you don't i'm breaking into your garage to take it for a joy ride.
Again, it is no big deal for me. Car is not my daily driver and I have no issues with it. Granted, they are not for everyone...but works for me. Different strokes for different folks
I do have the OEM cats on it also. Still, when you need to, you can go easy on the gas.
I just installed mine this afternoon. I have mixed feelings on them. They sound great but they are just a tad too loud for me. I'm 24 and have yet to lose my hearing and want to keep it that way so I'll be putting the stockers back on in a few weeks.
Nice
Do you miss the torque of the Z06? I test drove one and was VERY impressed with the massive power available from about 2000 RPM. In order to get the same zip from my 996 I need to be above 4,500+/- RPM. Different strokes for different folks i guess but the Z06 is certainly better suited to U.S. roads were you are often accelerating from low RPM.
I have had the Fabspeed muffler bypass pipes for over a year now and I love the sound! This is not my daily driver but I will not put the mufflers back on. They weigh 25 lbs each by the way....
You can control the noise with the gas but man that start-up rev is loud, coupled with the sound resonating through my garage I'm quite certain I woke up all my neighbors this morning.
Not really that bad. You have some control on the gas. My son sleeps above the garage in our 3 story house and he never wakes up. It is a deep low grumble. They are not for everyone, but work fine for me.
Also, if you pay for Fabspeed...you are nuts. They all work the same. I actually got my 996 with Fabspeed tips on the OEM exhaust that now sit in the corner of the garage. Granted I like their intake, but the exhaust stuff is way overpriced. This is coming from an Ex-BMW Dinan guy...
Again, these are not for everyone, but weight savings...other benefits...I like them and they stay.
After years of owning over 20 cars....and 20 year military retired guy, the exhaust is not a big issue. Come shoot my Kimber 1911 Raptor...that is loud.
Just a young at heart 40 year old here.
The PO of my car had put on bypass pipes. I drove with them for probably two months before I took them off and went to FisterD's. Love the Fisters, but I'd be lying if I said I didn't miss the startup bark of the bypass pipes. (Don't miss the drone at 2500 RPM, tho.)
For whatever it's worth, my wife, who is not a car girl by birth but loves the 996, keeps telling me I should put the bypass pipes back on!
I just love the bypass pipes...the reduced weight is a benefit also. No way I was going to pay some obnoxious price for an exhaust that did nothing but give sound. These are not for everyone but they work for me. To me, the sound is priceless....and if you know how to drive when a cop is around...no issues. I do have my OEM exhaust to swap back on with Fabspeed tips on it. Funny thing, the tips cost more than the bypass pipes. Hey, if these things make me smile even wider every time I drive the car..and I can take them off and keep my OEM exhaust....done deal..just saying...and they are not for everyone.
Glad to hear you are enjoying your purchase.
Do you notice the loss of low end torque? Dyno tests show these bypass pipes cause a loss of low end torque, because of the lack of back pressure on the engine, however they give a bump in high RPM torque and HP.
I've thought about trying the bypass pipes in the past, at least for AX and DE, but I've decided against them because I really like to get on the throttle on the street when conditions permit. With these pipes I think I would be hesitant to really get on the throttle because everyone for miles around will know. That is one great thing about the muted stock exhaust, when you nail the throttle on the street the sound does not attract too much attention.
I just got a muffler shop to install my e-bay bypass pipes this weekend on my 996 C2 Cab. I would have done it myself but I spent three Saturdays trying to get the rusted bolts to budge to no avail. The muffler guys were very impressed by the sound but admitted that even they thought it was too loud (and these guys love loud). I also love a nice throaty exhaust, but I have to say I'm a bit worried for my hearing after driving around town (I'm 23, so this is coming from a young guy).
I've been driving around all day and have to say I have mixed emotions. I really disliked the stock exhaust because it was like driving around in a flashy prius. Driving around with the bypass pipes is like driving a V8 with modified exhaust but twice as loud. I drove next to a new Mustang GT and there was no comparison, the bypass pipes were much louder. At idle it sounds very tame, but give it some gas and it sounds like hellfire exploding from your tailpipes. After driving around a bit, I think it's possible to control the noise level to acceptable levels just by upshifting constantly and staying at or below 2000 rpm.
I went to a friend's house and let him drive it around and his jaw was on the floor, and he had just driven a Lambo earlier in the day at a track event. So there's definitely appeal. We also stopped by a Starbucks and everybody was peering over to see who just parked. As we were sitting there, a Harley pulled in and left and I would say the bypass pipes are not as loud as a Harley, but very close.
My friend talked me into leaving the pipes on for a few weeks to try it out, so I'll have to see if it grows on me. One thing is sure, I'm definitely picking up a lot more attention for better or worse.
Guys just a warning about quality of some of the manufacturers of the pipes. A set came in yesterday , and I was hugely disappointed by finish product. Basically the oval tips weren't centered on the bumper line. Either a factory defect or just poor design. I'm in a process of straightening this out. Only way for me to adjust these is to cut the oval tips right after the 90deg elbow and twist them and then weld them back on. If I will be forced to do such a surgery, I'll try to look for turbo tips and weld these on instead of the original ones. They kind of don't fill the cutouts in the bumper well anyway ;(
Yes, I can definitely feel a loss of low-end torque at very low RPMS (below 2500). I can't say that I notice an increase in top-end hp or torque as the car makes enough power to not nearly matter below 100mph anyways. It doesn't bother me as I do believe you're getting a bit more power overall, but my butt dyno is just a butt dyno.
My ebay bypass pipes don't center up exactly in the bumper holes on one side. No one else has ever noticed though. You get what you pay for, and I didn't pay much so I'm happy.
These aren't hard to take on and off, but squeezing the mufflers in and out of the car sucks. I had no clearance between the inside of the bumper and the engine.
I did not really notice any difference in performance with mine. Still love them though.
There is a weight difference though. They will stay on my car, but still have the OEM mufflers in the garage.
My hearing is fine.....and the sound from the engine is bliss.
I could spend well over a grand for the Fabspeed exhaust....but why?
This is just my personal opinion and experience with the bypass pipes....and my pipes are not Fabspeed either.
It's not really that loud when you're IN the car. It's the poor people you drive by. I stood behind the car in a parking lot and let my g/f hit the gas once or twice and WOW it is deafening. I wouldn't get one in a cabriolet.
I had mine(custom by pass pipes) for 5 days. Its very very loud outside the car and loud inside. The only video thats describes precisely the bypass sound is this
You Tube
Its not for every day!!!!!!!
I'm willing to try it, I have a cop as a neighbor though so we'll see how long it can last.
Anyone else want to part with their mothballed set on the cheap? Maybe we should start a rental program as it seems the average number of days on a car is like 1-4 weeks...
