Aftermarket Header Gasket
 

While getting my car tuned the gasket between the flanges pictured below blew out.

I'm sure that the gasket i used was incorrect.

Could someone post a pic of the correct type. the collector pipe outside diameter is 51mm

Any advise or you have a spare will be great.

I would be hitting up an exhaust shop for that one, looks like a flexi joint. They're a cone shaped fiber gasket. Same as what goes between the down pipe and the mid pipe on a factory WRX exhaust.

Yeah, What John said. They're a universal thing just by size. Also, those headers usually come with shitty 8mm bolts, you can replace them with 10mm bolts and decent thick washers for better clamping, less bending.
