Copper donuts

[cr8zybaby]

07 attak,is the titanium exhaust gonna be ok with the copper donuts? Everything bolted nicely back together and there's no loose exhaust clamps etc.
Just looking to see if it's gonna last. Either way I'm gonna SEND IT

you will be fine the pipes crack most time because the stock donuts wear out and cause clamps to become loose the copper last forever. as long as the clamps went on tight those joints wont give you anymore grief. there are other areas that can crack and fail I would add support to the next joint in the system like the 08 and up sleds have so it don't fail there next.

My titainium cracked and warped all over. So I replaced with stainless pipes. No more issues and I used stock donuts and ground the clamps a bit so they tighten more

Did the same thing on my 08 as I don't have plans to get rid of it anytime soon so replaced titainium headers with SS and added the copper donuts.
