|February 8, 2010 - I've been looking at muffler and exhaust options as part of my push to sort out the basic packaging.|
Essentially, should I run two small mufflers or one medium size one? The goal is to get the car as quiet as possible, as I want this to be a cruiser. If it costs a few horsepower, that's acceptable. The dual pipes (say, 2.5") are easier to package than a single 3" one.
It's not an easy answer. The problem is the fuel tank. It's offset to one side, so to run twin mufflers I'd have to move it sideways. That's not a big deal, but even with that I'd still need some pretty narrow cans. For the single muffler, I'd be looking at a can of approximately 5 x 10 x 17 at most. Luckily, this is a pretty common size range, and I can choose from Flowmaster (excellent website, not a lot of positive comments on the sound from some people), Dynomax (many recommendations for the Super Turbo), Magnaflow (I have one on the Seven, it's so loud it's a running joke locally) and Hooker Aero Chamber.
Based on the recommendations, I think it's down to a competition between the Super Turbo and the Aero Chamber. The fact that the Hooker doesn't have any packing but relies on internal baffling is a bonus for long life. The good thing is that neither one is terribly expensive so I can experiment if I have to. I'd still prefer a pair as part of a dual exhaust, but I just don't think I can make it fit.
Fun stuff, though.
