The best sealing option for your VQ35DE headers to cats or test pipes is here is here. The CZP XT or eXtra Thick gaskets are custom 1/8 inch thick high temperature graphite gaskets with a stainless steel mesh core precision cut to the exact OEM gasket dimensions, sure to be the last gaskets you need. These gaskets have no issues sealing with slightly warped or "problem" flanges and give you the peace of mind that you wont have any pesky exhaust leaks anytime soon. Just make sure each flange is clean and clear of debris, install your hardware and make sure the gasket is slightly crushed and you should be back on the track in no time.

SOLD INDIVIDUALLY, 2 are required per vehicle. Not meant to be reused.

Please note: THESE DO NOT BEND! These are made from a compressed graphite composite material with a wire mesh inside to add rigidity. It's normal for them to have some superficial cracks, as they seal by getting squished together between your exhaust flanges anyway. Please don't try to bend them "just to see if they're flexible," because it will destroy them, and exhaust gaskets aren't supposed to be bent!
