Default Which exhaust gasket is the one between manifold and pipe? I think I have a leak

I swapped out my exhaust to stock so its quiet when I take clients out but I can hear a small exhaust leak. I recycled the 2 gaskets that connect to the exhaust manifolds which was a mistake. It's where each pipe connects just under the motor as far forward as you can go from under the car. What is the name of those gaskets? "Exhaust Pipe Flange Gasket Right WALKER" I see in what appears to be the one on ebay. I believe they smash into place so once you swap exhausts a couple times they must be no good. Thanks everyone

Also after getting on the freeway my check engine light came on and my traction control light along with the red triangle. I'll connect my laptop and see what codes are there. I can see an exhaust leak messing with the o2 sensors but I don't get why the traction control would come on.

VSC light comes on whenever check engine light does. You can get those gaskets at local auto part stores. I got mines at auto zone for like a dollar or two.

I got this one at autozone for $5.99. It was $3.99 at Oreilly but they were totally out of stock in the region. Even autozone had to order one. Hopefully you can see the pic and tell me if that is the write one. It should get the other one by 630p they said so maybe I'll put in tonight. Thank you

Thank you. Do I need to apply grease or anything along with it? Is there anything to hold it in place or just put on dry? I'm guessing dry is better since anything else could burn and mess up the o2 sensors.

I just read I need to use "high temp perma tex o2 sensor safe" compound. I guess I'll be heading back to autozone.

Remove the old gasket and simply install the new gasket. No sealants or anything is necessary.

Thank you. I didn't see that there was any before so that makes sense. Maybe more for manifold to engine is permatex needed

Nope, just either get an OEM or MLS gasket and install...no gasket maker or sealants are necessary. They're designed to crush and seal against the two components. I've got a set of MLS gaskets to install along with my PPE headers; didn't wanna chance leaks or error codes from reusing a single-torque type gasket.

Thanks. I swapped them out and it purrs so quietly. Now my clients can take me seriously

Now time to take off the plasti dip on the rims. I wish I could easily adjust the height up half an inch.
