Difference between Arrow Competition and Race-Tech Exhaust
I see that the Arrow Race-Tech Exhaust states it's only 98 dB at 7K RPM - which is perfect for here in Cali. I can get the increased HP while staying in compliance with their increasingly strict noise laws (and I don't have to worry about annoying my neighbors - I live in an apartment complex and I leave at 520 AM).
The price difference doesn't seem all that bad. I know with the Arrow Competition Exhaust they claim you need to get it remapped (I was going to do that anyways).
