I was going to suggest something like this through the hood. Been a dream of mine since I was a kid and got a "Rodger Dodger" Hot Wheels car.
If you're running a straight pipe with no resonators (things by the back bumper) or mufflers (under the car) on the street it should be plenty loud. In fact, you may have trouble with LEOs as that will be well above the legal decibel levels for exhaust.Hey what’s up guys, so I just recently got a hellcat and I want to make it as loud as possible. Any ideas? So far I put a straight pipe in with the cats and resonators deleted and its still not loud enough. Any suggestions would be great! Thanks!
