Holds very well

The gasket came in a nice packaging and holds a nice seal. Haven't had any issues after installing this gasket!


Fits perfectly. You will need this

Required for Stage 2!

Don't waste your time installing a J-pipe without this. You will have a leak and spend a lot of time stressing and looking for the leak when you can just use this to properly install your J-pipe with your catback exhaust (or the stock exhaust using an adapter) and make sure there are no leaks.

Must Purchase

If you are putting on a Jpipe I highly recommend that you purchase this. When I took my old one off it was rusted and worn. Its a must need product for J-pipe installation

love it!

great work as it shows!! better than OEM
