Not sure where to put this so i put it here. Move if needed. Ok well I bought a header off a friend and it didn't have the lower flange to connect to the cat. I think making one would be pretty difficult since the "donut" sits on the flange and the mounting holes need to be pretty exact. Is there a place that just sells the flange with the lil lip for the donut? I know Aaron Weir could make the flange but I need the lil lip on it so it can seal. And when you guys fab up your downpipe what do you use to connect to the cat? well any help would be helpful.

thanx

someone or any who makes theirown DP how do u have it connect to the cat

 

Yesterday I went to Midas and bought a basic flat 2 bolt flange, and a donut gasket thats flat on one side and beveled on the other, works perfect.

 

I just remove the cat so I don't have this problem

 

word to that, mine actually bolts to a test pipe, so that the cat can go back in for a day to run emissions.

which btw i pass better boosted than I do NA, weird eh?

 

Whitey and I hacked the end of my stock header and welded it to my downpipe, it seems to work well...Matt

 

well I dont have a stock cat its a 2.5 high flow cat. and I hacked my stock header and lost that flange. so i guess i will search for another stock header or a 2 bolf flange. What should the inside diameter be on the flange?
