I replaced a broken manifold stud, the one closest to the master cylinder. I officially freakin hate my racing mazda dp, it was a PITA to get to the bottom bolt!! And then replaced the gasket between the dp and cat, the old one was leaking pretty bad. I will be glad when I sell my car and start fresh with the t3 setup on the shelf, much easier to work on!!

 

after reading the thread title, i thought you had some ruff sex....
dissapointing thread j/k
are you using a 2 bolt or 3 bolt flange for your DP to cat?

 

the RM dp only comes in a 2 bolt, wish it was a 3 bolt though for a better seal.

 

cut both flanges of and weld v-band flanges and voila, never worry about gasket again...
