[QUOTE="RBB, post: 15726646, member: 152686"] I'd say you'd be really hard pressed to find someone who already had long tubes, then swapped mufflers and actually dyno'd it after that to see if they gained anything. You have already removed the biggest point of restriction, you're not going to pick up any power with a muffler swap. [/QUOTE]
