Aftermarket Exhaust Upgrade

[Joflewbyu2]

Your drilled hole doesn’t stop the mild steel case and baffle from rusting. They still rust and corrode inside. Hence the reason the OEM uses the much more expensive t304 non magnetic stainless steel case and baffle. Not only does it last longer but it weighs less too.

I had a very minor rust issue at the outlets at first...Drilled a small 1/8" drain hole under the pipe where the clamps are...Been on the bike now almost 5 riding seasons here in Michigan, and not one spot of rust anywhere, pipes look like new and sound just fine for me.....Cobra 6-2-6's....Regards and ride safe
