cat gasket question

[SCWDP911]

I am a little confused about gaskets right now. Getting ready to try out the euro premuffller with my M&K 1in 1out. I have a muffler gasket set coming. It had 2 triangular gaskets in it, but they looked the same to me in the picture. I already have a new lower cat to engine gasket, but in looking at some pictures today, I am wondering if I might be missing one needed gasket still? Is the upper cat gasket (to the crossover right?) the same shape and bolt pattern as the cat to muffler gasket?

Thanks,
Shane

I recall them being different.

I ordered the copper ones from Fabspeed and they did not line up very well. Called them, they said I was installing them wrong. I said they are unique to each placement, I can't install them wrong (without really getting off track). He said well, nobody else has had issues, so good bye.

Ok, @ss hat.

I ended up filing a little in the hole openings for the bolts to make it work....

The two gaskets cming and the one I already have are all oem pieces I believe.

They are 2 different gaskets. At the front of the cat there's one with an oblong hole and one (triangular) with a round hole. At the muffler end there's a different triangular gasket with a round hole.
