Aftermarket exhaust mount options.
« on: September 26, 2016, 11:00:42 AM »
Show me pictures of yours.
Anyone got a clever header support mount @ the rear frame cross member, or to the right lower frame rail?

I've had my CONE mounted directly to my passenger peg mount, and its worked well, but these welds have cracked over time, partially due to the offset mount location, and the thinness of the SS used on these CONE cans....and our i#$%*ty roads. 
I'm just looking for a better option/ideas.  Maybe a way to support the end of the header instead.

My neighborhood welder moved so no more convenient work....and the cost to weld a patch and new tab is roughly the same cost as a new can.

Thanks cal and jonda.  Kinda bummed that it cracked.  It was a good setup.  Might go try the open core 18" reverse cone and do something involving a strap. Id hate to go thru another one. Appreciate the feedback.

I have seen mild steel mounts crack. Often enough, the exhaust mount is loaded or sprung into position when fully secured. Shimming washers or spacers at mounting points and careful alignment removes localized strain to make for a best installation. Even aligning with loose but slop free hardware as you tighten the manifold flanges can offer stress relief.
