I'm looking to buy a loud muffler for my truck, but not too expensive. Where can I get a loud muffler (exhaust) or what kind or brand?
If it's a Ford, Roush exhausts are pretty badass. Pretty loud too.
cherry bombs,glasspacks they make your engine growl
First find out how loud your are allowed to be by law and then look for one that fits into that decibel range.
Pep Boys have a nice selection of tuned mufflers.
