i cut off the bushing lip on the 2-1 part of my headers that run into a high flow cat now it metal slaps when revving down on RPMS any ideas on how to fix?

 

Is there a gasket between the parts?

 

i do have a gasket between them right now but it doesnt sit flush between them and if i rev up the car in the morning or something you can hear a really bad rattle its like a metal slapping noise i need like a 1/4 " copper gasket or something to bolt them flushly together unless someone has a better idea

 

I'm not quite sure what you did... Is that one of those thick donut gaskets that allows the exhaust to flex (like a ball&socket joint)? That's gonna be difficult because you really have to make something that allows similar flexing when the engine moves.

 

hate to sayit but yeah it is the donut bushing this is KILLING me its friggin rattling real bad

 

It might be possible for an exhaust shop to weld on a couple inches of tubing, then flare it to kinda make it like the flare that was originally there. Find the kind of shop that makes their own pipes, not the guys who only know how to bolt on ready-made pipes.

Maybe find an A-pipe (that's the 2-to-1 section) from a junkyard, cut off the flared end, & weld it to your header's A-pipe. Unless maybe a factory A-pipe is the same then just use it??

 

yeaaa luckily im in the construction field and ive got the guys doing all the copper and stainless steel duct welding.... im gonna talk to the guy that does the stainless steel welding and see if he can hook me up if not im gonna figure it out.........some how

 

Let us know how it goes.

 

glad to say it has been fixxed no more bad *** rattling like that i cuztomized a steel piece to fit into the header and put the donut on that and of course after all has been done i come to realize that there was a crack in the exhaust pipe which has now been fixed so i hope to be on a road to goodness (keepin the fingers crossed) thanks blake
