    Exhaust gasket for 2.5 inch system?

    Hey Fellas,

    For those that have a full 2.5 inch system, do you use the 2 inch oem gasket between sec 1 and 2? If so wouldn't this create a slight obstruction? Is there a wider gasket people use?

    I will be separating the exhaust soon to drop the diff., if the gasket creates an obstruction I'll likely just trace/cut the gasket, I imagine this will work.

      Just order 2.5" gaskets from anywhere.

      A 2" gasket in a 2.5" system will cost you about 1.75" of area, which will absolutely cause a restriction.

        Im surprised no one has asked this question since the 2.5 inch system is so popular.

          Have you order one in particular that seals? If so, please share!
