Headers are on, fitment was above average in my opinion for such a reasonably priced setup. Having some issues getting the ORY to seal even with double clamping but i'll get it worked out. Can't say enough about how great these things fit.

Use heavy duty aluminum foil folded up as a gasket. Works great for a exhaust gasket.

And wide band clamps, been talked about on their thread about the headers, the included clamps suck!!!! Go to local parts store and grab a couple.. And it should seal it up along with aluminum foil trick!!

I've actually got it double clamped. It's getting better, just not completely gone yet.

This is pic of my v band slid over the end of my collector.. Notice the gap!! Its only that bad on one side.... Sticking a pipe expander in the end of the collector would most likely cure this but may explain the leaking issue..... Especially if y pipe expansions are as out of round as my collectors are.... Be willing to bet if youd run a pipe expander in both sides of the slip joints, you wouldnt be dealing with leaks....

I had 2 broken bolts on each side when I installed my Doug thorley tri y headers and couldn't get them out so I put high temp copper silicone on the gasket and over the broken studs and it hasn't leaked at all.
