Call me crazy, but I think adding a slight bit of back pressure actually helped my performance. Itβs (allegedly) a 2.0L motor and it came with an open 1 1/4 exhaust. I think the 1 5/8β CB exhaust is probably too big for it. I only drove it home from Indiana with that exhaust, a long time ago, and I rarely drive it without today (only when Iβm working on it and have to repeatedly open the clam) but it seems to have a little more torque with it on.
What I ended up with:
Cookie cutter from GT Racing
Megaphone fromSpeedway Motors
Perforated metal tubing from Amazon
