I recently bought 4-2-1 two piece headers and put them in my 2000 Integra. Everything went well, however there is an exhaust leak between the two pieces. Is it a good idea to have the pieces welded together, or is there another option like somehow finding a thicker gasket and replacing the original one?

 

It's leaking between the downpipe and actual manifold? I've welded them before, I've never really had to seperate them anyway.

 

just buy the gasket kit and make another gasket yourself.....its nor hard and all ya have to do is make a stencil of the size and cut it out....chances are, ya somehow damaged the gasket when installing it .....

 

just use some high temp rtv exhuast gasket maker..it comes in a little tube and is red colored..used it on mine and works great. you should be able to get it at any advanced auto, autozone, pepboys...ect

 

Get a gasket, preferably. Fuck that Exhaust cement shit. I promise you, you will hate that shit.

 

its not cement..its made by rtv..its a rubbery stuff...its worked great for me with no problems

 

Theres two things I used. The exhaust cement and the RTV. Both sucked ass. But, I guess it could be because I was boosted, producing more heat.

 

Is it a gasket issue or does it fit like garbage? Either way no offense dude but I wouldn't use that RTV shit.

 

could be...i used mine also to connect my 2 piece header because no one around me sold an actual make it yourself gasket.

 

Well, if you can do it right the first time. Do it. I believe, depending on your header. You can go get a header/downpipe gasket for a Type R exhaust manifold. If not, just the 7 dollar make it yourself gasket. Works just like the other, won't be perfectly pretty but, it's better than RTV that looks like a glob of boogers.
