Why not shorten a set of stock mufflers ? I'm with Canberra, i would'nt chop up a set of TORS when i reckon you would would get similar sound/performance from gutted and shortened stockies. Dont know if i would chop up what is a $1,200 (AUS) rear guard/fender either. Looks good short but i've waited until a damaged one has turned up. Let us know how you go with mods.
