Got Corsa? - ZR-1 Net Registry Forums

mike100 · 04-30-2012

I had the regular corsa setup on stock manifolds with cats- everything normal, and I thought they were too loud. Loud outside, little drone inside. So loud I got pulled over already going full throttle on the last block to the freeway entrance in town. I honestly believe it was the incredible loudness that got me popped, not doing 70 mph onto the on-ramp.

I went back to oem 2.7" pipes with an x-pipe instead of the resonator. I'm using 90 stock mufflers with the twin square tips at the moment, but may change mufflers in the future. it is really nice to be not loud again. it may be down a few hp over 5500 rpm- but it is hard to tell. The oem pipe is amazing as it doesn't resonate- no reason to throw away good engineering- if anything, its a bigger pipe size- kind of hard to argue against that.
