  • dude, take the gay ass resinators off!!!

  • @MrMicas101 ...maybe you missed it, but the cutouts are installed on the midpipes - after the catalytic converters and before the resonator. So when the cutouts are closed, the exhaust is essentially 100% stock. However, when the cutouts are open they are just going through the headers and catalytic converters (eg. no resonator and no mufflers).

  • @breedam- what did you expect?

  • QTP cutouts range from around $200 for single exhaust applications to around $500 for dual exhaust w/controllers. Im sooo putting these on my 06 GTO M6. Not that it needs it, our LS2's make Mustangs sound like leaf blowers....To the poster...Did you have any backpressure issues or torque loss?

  • @PattDomenici

    No issues that I noticed... but then again I didn't have it dyno'ed or anything. It's hard to really tell though since the sound is so overwhelming. With my SOTP meter, it seems like it rips harder with them closed... but it mentally seems faster when they're open since it's so loud and mean sounding.

  • That is so cool!

  • @iamcanadian2222 dude i have dual cutoffs on my truck, i know perfectely fine what they are and do. but if you take your resinators off your stock exhaust sounds alot better, my uncles got almost the same identical car.

  • dude 6,0 litres and only 400 hp??? wtf

  • @iamcanadian2222 a guy dynoed his with the same set up and he actually gained 2hp and 1.7 tq

  • 0:27 that rev scared me.

  • Feel sorry for those of you who have to have smog tests in your state. I like it in MS even thought we are so behind on things.

  • 500 for these or 600 for the spintech axle backs.. decisions, decisions... i love the sound of the spintechs, but i'm sure my neighbors won't at 6AM...
