sounds right.
i have a 2.25" full exhaust, a bmc panel filter and running optimax. so i would say thats about right.
dont b disapointed thought. i seen a skyline gts which got 75kw at the wheels LOL!
BTW dont get a cat back exhaust for a NA car. cat back exhaust only benefit cars with turbo. and stay away from the canon too.
what you want to do is the opposite of a cat back, where u make the front half of the pipe big, then make it smaller at the back.
this is so as the gases cool down and get more dense (there fore take up less space) you need to make the pipe smaller other wise it will create a vaccum. this will make you exhausts flow worse and increase back pressure, and you will loose torque, untill u are in the high revs.
if you want real life example look at the motocross bikes. they have a 3" pipe that shrinks down to a 0.75" in about 1.5 feet(rough numbers). the reason they do this is cos they need to use theyre full rev range, not only high revs like moto gp.
this is called a tuned exhaust.
i was told to go for 2.75" for about 3 inches, then 2.5" to cat, then 2.25" for the rest. but my exhuiast guy had no 2.5" pipe, so i settled for a 2.25" pipe all the way, might change it to see if the theory is right.
