I hate to act like a newbie and make an exhaust thread, but I guess I will. My truck currently has a "Heartthrob" single in, dual out muffler on it, that the previous owner installed. The guy that replaced my cat put 3" out of the cat and into the muffler. The muffler has dual 2.25" pipes coming out of it, no tips. They're not the greatest looking thing in the world, as a matter of fact, they're not even lined up even. Its not so bad that its noticeable, but I know that its there. The truck doesn't sound bad, surprisingly. The question I have is what kind of effect going to dual 2.5" pipes out would have on sound and possibly performance. My last Ram (a '97) had a Flowmaster 40 non deltaflow with 3" in and dual 2.5" outs. It wasn't too loud for me. I'd like to keep the muffler thats currently on my new truck, though. Any thoughts?
