I agree with unclejed.You probably won't be happy with how it sounds either especially when you let off the gas during deacceleration.It will make that annoying popping gurgling sound.Throw a set of Flowmasters or Magnaflow mufflers on it and you'll probably like it much better.Its also very hard to hear yourself or anybody else talking when running no mufflers.The obnoxious droan occurs at cruising speed too

Check your state and city guidelines in Michigan there is no emissons restriction it boils down to how many DB your car makes and depending on the citys limit but watch out because if its legal in one city/county if the next one over is stricter its illegal. Just get a glass pack

Technically it IS illegal.

Violation of EPA mandates.

So....even if your community/county/state doesn't have a particular law againstit....a crafty cop can ztill ticket you.

And a not-so-crafty cop wlll ticket you for

Something relse they find on your buggy!

Not worth the hassle.

very illegal.. it will eventually cost you a bunch and a half...

No its not illegal. But most cities have noise limitations so if you exceed that you can be ticketed....................
