muffler ?

My question is "Tool Loud for what???" Every town in USA has a sound level ordinance. Most cops don't chase you around with a decibel meter. I run Headers & Glass Packs out the side and I just take it easy in town and late at night. If you run it out the back, You won't hear too much inside the car.

Oh wait I see it now. You're in NJ where the cops hate kids, Muscle Cars and basically any thing cool. Yes Those mufflers are too loud for NJ. I recommend moving to NC.
