so my setup right now is a mac o/r h pipe and flowmaster 40s...sounds good...but not as loud as i want it to be lol.....and its rusting out and theres a hole in the pipe, so i'm wanting to get another catback but dont know what would sound the best with the o/r h...my buddy had slp lm1s when he had an hpipe and it sounded horrible so slps are out of the question, just give me some ideas guys of what you think would sound best
