What kind of exhaust are you running?

[deniswhite1]

on the old forums, someone gained 10hp to the wheels with a cold air intake and an exhaust job. I think it's worth it.

sounds like it.. thanks

sounds like BS (not startin anything here but proff would be good)

ill find the thread but I am pretty sure it was Brian and he did gain some but it has to be the right size piping... also he had the u/d pulley....so all together with intake, exhaust, and u/d he gained some but who knows what did what

I am using 4-1 header. Removed cat. 2 inch mid pipe with a 2 inch mid silencer (straight through), and 2.5 inch tail straight thru muffler. From head to tail straight through all the way.

Havving straight through and 2 inch let your 0-1.5k rpm faster, less choky feeling. The rpm rev faster, but means that your rpm have to always rev above 3-4k to get the power. You cannot expect to rev 2-2.5k, and expect the car to move. The back pressure is removed. You need to rev more. But when you rev more, the power is more.

With original 1.75 inch pipe, cat and tail muffler, it is very choky, every time you release accelerator, your car will jerk. With straight through, the exos is much smmother, enabling you to high rev smoothly without choky feeling.
