Its not an obnoxious exhaust by any means and has zero drone going up hills. I kind of wish it was louder  . |
Best M performance exhaust setup I have heard yet! Congrats Justin! Holy cow!!!
What affect would you say the downpipe has on the sound of the M performance exhaust (if any)? I am not very familiar with down pipes. Do they increase performance or enhance the sounds?
