Ok I cannot afford a catback system right now. I want to just replace the mufflers only. I know Im much noting much if any hp by doin this but I want my car to be louder. Iplan on using the stock GT exhuast. Can anyone reccomend any mufflers mainly the size ie 2 1/4" offsest inlet outlet..case size etc...I figure for $100 I can get two mufflers and install it myself at work....being a single dad I really cant spare the extra $150 or so for a cat back...
