I bought some 2.25" stainless 3-bolt collector flanges for installing my carsound cat - well, I can't seem to find any 2.25" collector gaskets! All are 2.5" or larger. HELP!

 

Buying parts to put together an exhaust system has gotten real bad now a days! I recently had to run all over the place to find flanges and it seems that most exhaust shops don't stock anything anymore. (I'm old and it's kind of a reflection on "the good old days")

What I'd recommend is to find an exhaust shop that deals with street rod or domestic hot rods. These guys go more for doing a custom fabricated system and not something that is just "ordered".

Are you talking about the doughnut that goes on the header collector? If so.. Check http://www.acuraautomotiveparts.org/ in the itr section because I think the usdm itr header has a 2.25 collector.

Goodluck.

 

Well, the collector flange from burnsstainless.com is flat - so I don't think the doughnut will work (anyone)? If it did, is it 2.25" in diameter? I'm not 100% sure....Here is a photo of them:

 

the donut works on a flat surface anyway, thats how they are designed to work on a factory application. if you arent comfortable using one a flat collector gasket will always work just fine.

 

That might be the best thing - use the ITR doughut....I'll have to see if it is 2.25". I tried looking everywhere (even ordered a couple of gaskets from Jegs which said they were 2.25 copperseal, but they had a mistake on their web site)....Only other solution is to use some high temp gasket material - but that worries me since this is the cat (high high temps)....
