im planning on upgrading my exhaust now that i have a built motor. right now i have mac long tubes 1 5/8", mac o/r h-pipe, and flowmaster cat back.

well i just got my car tuned because i got trick flow twisted wedge heads, trick flow stage 1 cam, and trick flow street heat intake. then all the other bolt ons. well my question is i want to go with 1 3/4" long tubes, but would it be too much to go with a full 3" system?

would i loose power by doing so, or should i just stay with a 2.5" system?

I think it may be too much. I don't think you'd need a 3inch unless you put a stroker in.

Stay with the 2.5" exhaust, and the 1 5\8" headers are fine as well.

I agree do not change the exhaust the 3 inch is not needed until you reach sick power levels like outlaw or renegade

I did it but then again I didnt have every thing you already had I would stick with what you got and put the money elswhere you could get a nitrous kit for the price it would cost to that swap if going even faster is what you want or maybe invest in aftermarket axles so you can run slicks when you take it to the strip.

stay with what you've got....unless you have some crazy big stroker, or forced induction you are not going to need a 3" exhaust for any reason....you probably won't lose any peak power, but you may lose some low end torque due to the lack of backpressure....remember in NA setups it's all about air flow VELOCITY, not so much the ammount of air flow....
