I recently installed the Magnaflow Catback Exhaust system on my 2003 Z. For reference, I purchased the car with stillen headers and a vortech supercharger. The Magnaflow sounds good in lower RPMs but has the dreaded rasp right around 3k RPM. I have yet to find a definitive solution that I can use to cut down on the rasp. If anyone can link a resonator that would help with this is would be much appreciated.

Thanks,

Mac
