I have a few extra 2.5 inch flanges. You will need this to use a header with a 2.5 inch collector such as the JDM ITR 4-1 or the DC JDM 4-1. They are for 2.5 inch piping and have a 4 3/4" bolt spacing. I will let them go for $15 each shipped to your door. Email me at: IntegraGSR95@hotmail.com paypal preferred.

 

is this the stock looking one or the AM-AIR-I-CAN crap?

 

it is a flat flange, you jyst slip this over the pipeing, flare the end of it and it will bolt right up.

 

of what are they made? i prefer stainless steel to match the rest of the system (and not rust from the road salt and water here).

 

BUMP they are thick *** steel

Don't most muffler shops have them? I haven't thought of checking at my local place where I was planning on having them custom fit my cat to the header.

 

It really depends. Lots of times you can find a 2.5 inch flange, but the bolt spacing needs to be 4 3/4 inches. A lot of muffler shops have them close, but the bolts will be slightly crooked.
