Cutouts

How much rwhp does cutouts offer? I know on camaros and t/a's it usually around 8-10rwhp.

The amount you gain revolves around how restrictive your current exhaust is .

Ive seen ppl make almost 100 hp with a big turbo , big cube street car and ive seen ppl make 5 hp ,, lol

I have read dyno results on the tech forum where they also gained zero!Like the previous post,it depends on how restrictive your exhaust is.I think they are more for WOW factor really.

I'm running the ZO6 titanium exhaust catback and make mid to upper 400-rwhp. I picked up about 10-rwhp by adding cutouts.
As someone else said though, I primarily got them for the sound.
