You just bought your LS1 and plan on using the factory exhaust manifolds, but noticed they have odd shaped collector flanges. Now what? These flanges bolt to the factory factory manifold and allow for a smooth installation. Flanges are 3/8" thick.

what size exhaust pipe will fit the hole in the middle? We use 2 1/2" on all our projects and if this flange fits the odd shaped flange on the left, plus our 2 1/2" pipe that would be great. Would be even better if you offered them in 1/2" thick!!!!
