Cherry Bomb mufflers are typically glass-pack style units, which tend to blow out reather quickly and lose thier "effectiveness" as a muffler. Then they really start to sound like crap. If Cherry Bomb is making multi-chamber style mufflers, then they might be allright. I'd probably stick with a more "known-for-quality" brand like Flowmaster, Borla, Walker, Flowtech, etc. Remember that usually, you get what you pay for.
