Today me and my buddy were installing my Downpipe and high flow cat and the thing is leaking real bad at the Header--downpipe connection point. I cant figure it out for the life of me and we have repositioned it and tightened it a million times. We called it a night but 2morrow we are working on it again but I need my car!!!! Any one got any ideas?

BTW: I have the random tech downpipe and cat. and a DC Sport 4-1 header.

Its not really a gasket so to say...its more of a funnel shaped thing. Ive got it tightened down to where and impact fun doesnt move it any more. Good ideas though

well then it definetly is tight enough. and yeah i just remembered how that section is connected. are u using the bolts with the spring or are u using some sort of aftermarket ones?

and if ur using the ones with the spring, are u trying to tighten the nut or the bolt?

That was one of my guesses too. Maybe its just not sitting in there right? Its pissing me off because I spent a lot of time trying to get it in there right. DAMNIT

Anyone got any ideas? Its one bolt that is making the whole thing leak! Should I take it to my muffler shop and have them finish the thing?

have u tried taking it completely apart and reinstalling it? you might notice something you did wrong. and u should try today and if u cant do it then take it to the muffler shop, theyll prolly over-charge u massively just because of how small a job it is.

I guess im gonna rip it all apart...lame. For some reason I think the little gasket thingy is screwin the whole project up.

check out the gasket, make sure its solid and doesnt have any cracks or anything. make sure its not just flat but can actually be compressed(if that makes sense) between the header and downpipe. it does sound like something is wrong with the gasket though or ur not tightening something the right way. u did say that the springs on the bolts were compressing so thats pretty wierd then.

OK...so I fixed the leak from the header to the downpipe and now its leaking in the rear and Ive got those bolts tight!?!?!? Any one know if there is a gasket that goes there that I screwed up?!?!?!? Any help would be greatly appreciated.

well yeah, there should be a gasket between the downpipe and midpipe.

did you take the metal part off the bottom of the stock header and put it where the header connects to the downpipe? Its like a little round thing at the base of the stock header. Costs 10 bucks for one if you want a new one.

just get some permatex and spread it all around that dounut and let it dry, then slap it on
