Thinking of getting a catback,I have single chamber flowmasters now and they sound very good.Would I be better of just getting a O/R X or prochamber or a new Catback.I'm leaning towards the Magnapacks and am wondering how loud are they?

 

If it was me, since you already have flowmasters(welded in I assume) Id probably get a Xpipe. The Slp has removable cats, and you can get straight pipes to put in their place if you wanna wake the dead. My 12 cents.
