Thread: Rear gasket not seating on DP...

Mine did that a few times.

Get some copper RTV, and lay a bead on each side of the gasket. Smoosh it onto the DP, or the cat-back, and try and keep them nice and level (using jacks helps quite a bit)

And slowly tighten each bolt, going back and forth. That's the only way I could get mine to finally seal.

The exhaust deffinetly smells alot different without the cat tho. Well and exhaust leak
