need advice on exhaust flanges.
need advice on exhaust flanges. i posted this in the external engine section but didn't get a response.
i'm looking for a way to use my stock '01 camaro manifolds with the large flanges for my conversion without a lot of expense. i've got the clearance for the manifolds but from reading the threads, it looks like the exhaust shops won't have the flanges on the pipe side to build the system. should i be roaming the junkyards for used pieces or is there an easier way without a lot of expense?? thanks.

I used these in my exhaust to connect the header collector to the tube to the muffler-

In addition to having them lazer cut, you could also get them waterjet cut.
Around here a pair of quarter inch flanges would be a about $20

Thanks guys. I'll pick up a gasket set to use a template and take that to the machine shop. I'll also go by the muffler shop and see if they can supply the bung and install it for the passenger side.

I just bought the standard 3 bolt hole flanges with the correct ID from the local auto parts store. I welded mine on the manifolds in place of the stock ones (which I cut off). Exhaust shop should be able to do that for you if you don't have a welder.

I used a dead catcon/headpipe from a 99' Corvette donor, cut the pieces off and welded them to my new system......looks factory now and was able to use the factory Corvette donut seals.....no leaks.

Steve,
I cut my own out of 1/4" mild steel and they bent and leaked like crazy when I tightened them down. I ended up welding the flanges right to the manifold to get it to seal. I think that finding the cats and cutting them off sounds like the easiest to get a good looking (and well sealing) joint. I want to get headers sooner or later, so welding the manifolds up really didn't bother me. It's possible to remove the manifolds, it's just a PITA.
