Where did you find them? What is the part number? I have a leak that sounds like it is coming from the motor but I forget how far in front the headers are in relation to the driver's seat.
Grab a tape measure and ask them if you can run thru the gaskets....Usually all those exhaust ones are lined up in a box or something....Look for a 2.5" I.D. hole and your good to go...Just dont get em to thick, like a 1/16 or so is cool...
Thats how I found the on above...looked thru em all til I came across the right size...
Don't use gaskets.. They leak after a while no matter what. Just do what I did, have it welded... I only have 2 gaskets on each side where the headers meet my H-pipe, from the H-pipe on it's all welded.. And I keep a close eye on where they meet the headers.. Checking it atleast once a month.
Having it all welded does eliminate any chances but then it makes it a pain to take it down as u have to cut it...then u have to go back to the shop to have it put back together and welded back up.
when i went to Napa. the guy looked in a catalogue, and it didnt match anything. i told him its a 2 bolt pattern and he said they dont make a 2 bolt exhaust gasket. i said whatever and left
i'm gonna go to another place to see what they got.
its a leak coming from my drivers header to h-pipe. its annoying when its cold but almost goes away when its wared up. the guys who built my h-pipe didnt align it perfect to my stock headers and now its even worse with my Mac unequals. i'm gonna have to modify the pipe a bit but want to run gaskets just in case too.
i went to another parts store last week and told them exactly what i wanted. a collector gasket with only 2 bolts holes and 2 1/2 opening.
he flipped throught a dynomax/walker catalogue and found it. the part number was 31337. when i got the gaskets, they looked just like Rio-5.0's except these had the metal ring in the opening. so andys gaskets are a walker/dynomax brand for you guys that are interested
put them on today on both sides and started the car up while i prayed.
right when i fired it up i almost **** my pants. NO EXHAUST LEAK!!!!!!! it actually sounded quite LOL. took it for a drive around the block to see how it sounded and i love it. it sounds nice and solid. it actually feels alot better according to my SOTP meter
