Here is my review with pics...
*update*
The stock header gasket works fine, but the downpipe flange gasket does not, so here's what I did.
I used OEM part number 90570544 L series gasket - $10.65
part number 21006315 nut - $0.96 each
part number 11508477 bolt / screw 8 x 1.25 - $1.87 each
Pretty disappointed in the finish of the ports. They were very rough. here is the collector port area.
same with the primary ports. They were rough also, and the gasket is WAY smaller than the header port size, I don't know if this will create a problem or not...that's yet to be seen.
The header also comes bare (but it's stainless), so watch for possible rust.
