hey guys im looking to do a full exhaust.do yall think it would be worth it . about how much horsepower should i expect with mac long tube headers,o/r x or prochamber and weld in mufflers. and what do yall think would sound the best out of pro chamber and straight x and muffler combo.thanx

 

Pro-chamber and X-pipes have 2 totally different sounds. The Chamber sounds like an H-pipe and the X is more of a raspier sound.
