Ok, I'm new to the v8 world, and I have a question about straight pipes. I got rid of my mufflers so i have 2 1/4" pipe from the catback. I heard that I might have a lack of back pressure now. I stuck with the 2 1/4" because I heard that any bigger w/o mufflers could cause me to lose torque and h.p. So did I lose h.p. and torque even though I stuck with the the same size pipes?

Probably a little. Are you still running the stock midpipe(cats)?

Yea. I didnt have a high flow and the mechanic wouldnt touch it.
