Resonated Test Pipe
 

My 99 gsr the cat is starting to get clogged. Alot of people are telling me to just bang it out and use it. But im leaning towards a test pipe. I had just an ebay one on a previous car and it was too loud. And the cops around here are strict and plus it was just too much.

Anyone can recommend a decent part to replace it? I have a dc header and a greddy sp2 exhaust if that matters.

Any help is welcomed. Thanks
