Ok so I think most of us have all experienced this issue. You go out and buy a new exhaust/muffler, put it on, drive on it and a week later the noise is killing your ears. You try to tell yourself it sounds cool, but your girlfriend/spouse says she can't hear you over the "drone" of the muffler.

So what if a company produced a muffler that was a universal product where everyone could put one on, still have the exhaust rumble, but without the drone. Basically be able to "tune" the muffler's sound to your liking. Would you buy it and better yet- how much would you pay? Most muffler sell between $35-$200 depending on the brand.
