ok this makes a big difference to me in buying an exhuast, replaceable parts is better than scratched or damaged pipesJust got done re-packing it and putting on a new carbon sleeve yosh makes it very easy to repair there products in most cases if you go down you can order the parts instead of a new pipe which is a big cost savings as you know.
Shoulda went w/ the single exhaust man... But enjoy, anything beats stock!
