Just wondering how loud it would be if I were to put just a muffler on the wrx. I have a borla 2.5" straight through muff, but its pretty loud right now on my Z24, b/c I removed the resonator. Just looking for confirmation that it should stay pretty quite with a stock setup and just a muffler, right?
Doing something similar to matt's mattspec
Invidia DP (replaces both cats) to custom mandrel bent midpipe, to custom bent 2.5" in/out Borla, and borla muffler tip (Thanks matt :P)
All in all, costing me about $500 total (That's very good pricing on the Invidia DP, and no cats. Muffler was $85 on ebay shipped..25bucks for piping)
