Cat/Muffler
 

I need a new muffler for my 2.3 92LX, so I figure I may as well buy one that will give my hp a little boost. Could anyone give me some suggestions for a legal performance muffler/catalytic converter setup? I don't want it to be loud and obnoxious, though. A lot of 2.3s with performance exhaust sound like souped up weed wackers. I'm trying to avoid this, I just want something that will give me a little extra power. I would really appreciate it. Thanks.
