Our cars have a huge resonator so no mufflers is actually not that loud.it's actually very cheap and easy. saw off the mufflers and you would have the loudest car in the whole city. in fact, your car would be so loud and annoying, you would be ticketed just about every hour.
If all you were looking for was sound, than yeah $50 did the trick..A friend of mine cut the mufflers off and welded a strait through pipe to the tips, it sounds just as good as the joe-z or borla and all for $50.
