Exhaust clamps provide quick installation and removal of said component(s) in lieu of paying both money and a visit to the local muffler shop. In my very humble opinion, exhaust clamps work best for single connections. For example, y-pipe to catalytic converter (1) to mid-pipe (1) to muffler (1) to tailpipe (1). Will venture to say, most people (self included) recommended welding the x-pipe onto the exhaust for longevity purposes versus using four exhaust clamps to secure it in place. Cannot deny or confirm the availability of a bolt-on x-pipe for the G8.
