Hey everyone, so i'm just looking for some insight on some exhausts that i've been looking at recently. I currently have a 2014 sv650 with a stock exhaust, which i want to replace. I have been looking the M4 slip on and the two brothers m-2 slip on. Also someone recently mentioned the delkevic exhaust on a previous post but i think i enjoy the sound of the other two more. Does anyone have/had one of these two exhausts? Do they increase performance at all? The costs are quite similar also. Thanks in advance!
