Hey guys, I went ahead and swapped my fabspeed out for a stock exhaust. The car is certainly quieter but to be honest I was expecting there to be a bigger difference in sound levels. I also still have some resonance around the 2000 to 2500 RPM level, it would be really great if you guys could give me some advice on if anything can be done to reduce this. If anyone is interested in my fabspeed, let me know. I'll let it go cheap. Thanks for any advice!
