I just picked up an FBF X-over from a member here, very happy btw.
Fitting the piece is more of a pain than I thought it would be. I know the idea is to "relax" this exhaust system so everything slides on nice and easy fits tight to help with expanding/contracting and hopefully reduce cracking. I have a couple questions here.
When loosening the collar at the head to header should I replace the gasket? It doesn't leak but looks to be aluminum?
The only way I can get this thing remotely close to lining up is stressing the headers a little, the gap between the studs on the collars is a little uneven about 1/8" difference top to bottom. Is this considered relaxed?
Last up how far (guesstimate) do the stock mufflers slide on the aftermarket x-over? Seems much less than stock about 2" or so?
