Hanger Problems

The Pypes sound great. They are loud. The hanges were way off. Three of the four hangers had to be re-welded. I was very under whelmed.

do i need to refer to state laws before applying these? Very interested but my understanding are these are pretty much going to convert my stock setup to straight pipe and some tips? Is this correct?

  • They are not obnoxiously loud so unless you are blatantly and consistently disregarding a cadre of laws while driving, you shouldn't have a problem.

    Mean Exhaust from a V6 Owner

    I think I may be the first V6 owner to review this exhaust because I couldn't find any which had me worried of what to expect. No, the hangers don't line up even for the V6. Shop took care of that no problem. Worked great with the new Pypes x-pipe kit. As far as the bumper I bought a GT500/CS OEM re-manufactured bumper to replace the original (~$700 painted). However I had the original on for a while before I got the new one and cut some holes in it with a dremel. Honestly I thought would look terrible but for a really quick cut it looked great. Note that not only did I have to cut the driver's side hole, the factory hold had to be made bigger otherwise the bumper would touch the tip. You'll want at least a half inch of clearance. As far as the sound it's awesome! It won't sound like a V8 but it has a really nice raspy race car growl; not ricey at all. A couple little backfires here and there when rev'ing in neutral from a cold start but it stops when I start driving. It'll probably go away when I get my intake/tune or the computer adjusts for the new airflow (installed earlier today). I haven't tried resetting it yet as it's hardly noticeable. Tuner/CAI is the next upgrade!

    Hanger adjustments needed

    Like all of the other reviews, you do need to adjust your hangers, this was quite a pain to install the passenger side, but when it was in, it was very loud. I have the pypes off-road x-pip and now the muffler delete system...way to loud and raspy, putting pypes hi-flow cats on soon...will review after.

    2010 GT

    This exhaust makes your car the best sounding thing on the road.There is A seat of the pants increase of power. Another thing the other reviews don't mention is that even if less than 10hp is added this exhaust also removes around 50 lbs of weight from the car along with a few other tricks it adds up. Only down side is the fit of the hangers.

    Pypes sound great, install was pretty easy too, Only issue I have isd the same as most of the others, the Right side will not line up and I don't have time to mess with it right now. I just find it hard to believe that after 3 + years of product reviews the company hasn't made an effort to correct this issue. Only other issue, I was told I would need the hanger kit, they are the same as the factory hangers, don't spoend the extra cash if you don't need to.

    Sounds great, but.....

    The exhaust sounds great! Has a nice rumble to it while the car is idling, and has a nice roar when you are accelerating past the 2500 RPM range up to about 4000 RPM. Only problem is that the hangers are not cut to the right length and shape to fit properly. I installed myself in just over an hour, and the right side ended up about an inch lower than the left. Took it to a performance exhaust shop and got the hangers fixed to fit properly for only about $10. Shop owner said it is an ongoing problem with these Pypes exhausts. Still happy with the purchase though.

    Great Sound

    Amazing from the get go. Deep, throaty sound, but still comfortable at idle speeds. The sound is perfect between 2000-3500 rpms, after that it is still loud, but smoother and more similar to the stock exhaust. However, quick accelerations are sue to turn heads. Another thing I like is the Pypes logo engraved atop the muffler tip. It adds a nice extra flair. Definitely worth every penny, the Pypes muffler delete is the best muscle car sound i have heard yet.

    Fitment Issues

    Had to bend hangers and had to cut slices into the pipes so they would clamp down to the H-pipe. But after we got'em on we fired it up and it sounded like a Hot Rod. 2008 Highland Green Bullitt Mustang

    Pypes rocks

    I am very picky about sounds, was never happy with the sound of Flowmaster or Magnafllow so decided to try this one out. I heard the sound was loud so I tried it and all I can say its DAMN! This system gives the loudest sound you can get, it really does sound AWESOME. On my first day out driving I got complements twice, I was asked what did I have under the hood twice and GIRLS love it so keep your windows down and be ready to get some numbers! I do have a 2005 GT with other mods, like K&N cold air intake, pulleys, computer, 3:73 gears, Cobra package (wheels and emblems) so now the car does sound like a true cobra! I do recommend this system to anyone, you won\'t be dissastisfied and the installation its only 45min.
