I currently have a Flowmaster cat back that's been hacked up some what. It's been necked down from 2.5" outlet's to 2" or 1.75" can't tell outlets as to be able to fit the stock square tips on it (what ever size that is). I have long tube's, off road y pipe and cam and such. I don't like it, it's loud droning, loud. On local Craigslist a guy has a SLP cat back for sale, it's the quad tip outlet one. Is this a good cat back? I've heard/read the SLP two out the left are the best cat backs. Are they still available? I've searched and can't find anyone selling them. I can't see how it would cost me any power by changing to something more plesant to listen to, am I right or wrong? Please help me make the right decision.



P.S. This fourm has been great, thanks to all on here.
