I was wondering on how to make my car louder and
I asked a few people so I had a question do muffler
deletes bring a check engine light?
Deleting the muffler probably will not trigger a trouble code but it will trigger a red light on top of a cop car.
Or a pissed off neighbor might put pop knots on your skull. Drive that loud unmuffled piece of crap in my neighborhood and see what happens.
