hmm, in most cases its illegal, but the law isn't exactly black and white. Let us not all forget the SRT-4 which comes without a muffler from the factory. Your mileage may vary on this one. Can depend on the length of your exhaust pipe, if you've got a cat (and its really, really illegal to ride around with one of these....not to mention bad for the environment, and more than just a bit of noise pollution :jerkit: ) or are running duals. Part of the reason why the SRT-4 has dual pipes is to help lower resonance on the exhaust..... However, it is a turbo car, so their exhaust is generally quieter anyway, due to the fact that the turbo tends to disrupt the noise coming from the engine.

I have ridden to 50 miles to dallas GA, open DP in the turbo v0 and my car in open DP is quieter than the over-cammed, lumpy mustangs that are out there. Anyway, on all of this, YMMV.

If you are still unsure, just buy a borla or dynomax straight through and stick it on there. Either way, the car will sound like absolute ass, but at least you'll have a can on there to show police should you ever get pulled over. HP loss is minimal and in most cases, you can look through the damn thing anyway. The N-1 has almost no baffles in it; you can actually almost see through the muffler.
