Which one should I get. I'm getting a SI/SO 3" exhaust system and don't know which one to get. I like it loud on the outside but don't want that droning sound on the inside. Just a good deep rumble. Thanks,
I got the 14" 2 ½ single in and 2 ½ duel out to duel exhaust out the back. It is quieter then I thought it would be. Almost can't hear it in the cab. Nice at full throttle.
