Hey guys, for my exhaust on my 03 I have TopSpeed Resonated Test pipes, AAM Y-Pipe and an invidia N1 exhaust. Right around 3k RPM it is so loud and the tone of the exhaust sounds almost like a loud trumpet. Also my exhaust noise seems to echo and bounce off every building I go by. I don't know whats making the noise echo like that, would taking off the N1 cat-back and replacing it with just pipes eliminate the echo and or make it sound nicer?

 

Get rid of the test pipes.

+1. Get rid of those test pipes. Go back to OEM cats or switch to high flow cats. UR makes some nice sounding high flow cats.
