I installed FPA headers on my car and am about to install a new exhaust. My question is connecting the exhaust to the headers.
The headers end in a 3" collector. The headers included a ball coupling reduced to 2.5". In the attached photos, the outward flanged piece connects to the headers via the 2 bolt flange included. That all bolts up fine.
The 2.5" exhaust includes a flanged end which I suspect bolts up to stock manifolds. The ball coupling reducer fits inside the flanged end of the exhaust fine, but I have no way to bolt in together.
I don't yet weld (though will learn at some point). Is there a way to bolt the reducer side of the header ball coupling to the flanged side of the exhaust without welding? Or do I need to learn to weld real quick?![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Any help is appreciated, and Merry Christmas (almost)!
