Ya, I got pulled over twice for my muffler on the car, i was running no cat with a jap racing pipe. I hallowed out my cat so the cops thought i had one on. I know that it was illegal, but i used it until i got in trouble. Since i didnt fee like paying a $120 fine(In Pa it is illegal to modify your exhaust beyond stock)I purchased a magnaflow high flow cat with a toucan racing pipe. The car is half as loud now but I once again got pulled over. I want my car to have a nice sound, yet there is no way to do this around here. Would using a glass pack/cherry bombs resonate the sound to make it quieter? Is there any pipes out there that will just amplify the stock engine sound?
