4 Stars   05-10 GT Pypes Mid Muffler catback
By on 8/22/2014
I'm very impressed with the sound! My car is a 10 and has a 12 lower rear valance. Tips filled it out perfectly! This is actually quieter than the Flowmaster American Thunder axle backs I had on the car previously. There is a slight drone at about 2k rpm but very livable. The only downside is the fitment issues it seems everyone has. The muffler shop I went to had to remove the hanger (one closest to the rear) on the driver's side to make it fit. They also had to bend a pipe slightly to keep the driver's side muffler from touching the gas tank. I've read where Pypes blames the muffler shops for fitment issues stating this is a difficult system and extra time is needed to get it right. However, I really don't think that is the issue. You get what you pay for. Overall, a good exhaust for the money. Just find a good muffler shop. Special thanks to Triple A Muffler in Garland, TX that fixed "almost" fit to fit on my car.

Yes, I would recommend this item to a friend!

4 Stars   Awesome sound

I ran this exhaust on my former 2007 GT along with the cut-in x-pipe and was very pleased with the exhaust note. Even with the factory cats in place it had an aggressive tone. Not too loud though, nice and smooth. Fact is, that is my car in the sound clip video.

The 4" tips matched the bumper cover perfectly and the mufflers being located further forward did not cause any clearance issues with the driveshaft or the ground.

The only gripe I have about it is that I had to take it to the exhaust shop for final fitment and some welding. This minor detail would not keep me from buying it again!

Yes, I would recommend this item to a friend!

5 Stars   Great experience

Maybe I just got lucky but every fit perfect on my 2010, had no issues what so ever! One thing tho the other reviews say "not too loud" but for me ha this exhaust will wake the dead ! Sounds great I get compliments every where I go! When you are driving like a normal human being it's not too loud and sounds a amazing but when you hammer down I don't think the mighty god Thor could make a louder sound. One reason mine may be louder than the other guys that left reviews is I have long tubes and a H pipe with no cats.

Yes, I would recommend this item to a friend!
