so iv heard that this exhaust setup doesnt have a loud drone, or noise inside the car when crusing. what is your opinion on this because i am looking at multiple setups for my car and this is one of them. what is your overall opinion?

[steelstrings1312]

i have violators on my 06 gt and they're amazing. gets a lot of attention.

i wanna be your neighbor and wake up to that sound every morning.

It always seems that S197 guys ether have long tube headers, and a complete exhaust. Or get an off road H or X pipe then leave on the stock exhaust manifolds. Why is that? Oh, and which one would see a higher HP/TQ increase without being stupid loud?

[crestfallenode]

well the new gt exhaust system, including the headers, flow amazing and are big 2 1/2 inches. However the cats are extremely restricted, and high flow cats can gain us 10 hp and off road pipes 17-20hp. chainging our axleback does nothing for us except mold the sound. Actually if you have no cats and no mufflers u lose backpressure resulting in a slower car. People get LT cuz they sound nice, headers do nothing but take low end away for us unless we have forced induction via s/c or cams

The stock cats flow just fine. When I had no cats I gained 3RWHP, but lost 2rwtq. I could feel the loose of tq in the lower RPM ranges. I added hi-flows and I gained a little hp and tq over both the o/r and stock h with cats.

@gragra73 did you retune it both times?

[jakeandaim07]

I think it sounds hott sweetness!

@jakeandaim07 the offroad X-pipe without cats and with headers is an ungodly loud combination lol
