I have a really important question for anyone willing to offer their advice. Since I use glow now, I know the pro's and con's of a full-length tuned pipe. That's kind of out of the question here! My question is: What's the difference between a Pitts/Wraparound and a Canister muffler?? I'm looking at the KS-86S since it has a smoke coil built into it. I've seen a lot of things about headers and stuff. Does this need a header, or is the $150 thing a plug-and-play thing? Also, what do y'all think the pro's and con's are? If I bought a pitts/wraparound it'd either be the stock $69 DA muffler or the J'Tech Wraparound. Input????
