Go with rockers, that's horsepower

is that a pay in the ass to install?

hehe sorry I meant pain in the ass not pay! haha

I dont believe you should attempt a rocker install unless you are somewhat mechanically inclined. It'll take a few hours to do (2-4hrs) seems to be the average. I dont know how good the installation instructions are since I have not pucrchased rockers for my GTP.

The off road pipe is not meant to bolt onto an exhaust unless you fab a 3" system.

Bolting a 3" -> 2.5" would kill your flow. That was the point I was trying to make... I hope I was clear?

If you want something for daily street use, etc, I was recommending the high flow cat as that would let you use stock or afgtermarket exhaust systems.

Thanks for the help MrQuija

Could I have a custom exhaust kit made for me with 2.5in pipes to do away with the cat?
thanks
