What is.....

[Cablefed]

I need to get two nuts for the exhaust section of my Evo 16G Exhaust housing. I need to know the pitch and size of the two nuts that bolt the down pipe up to the O2 housing. The turbo is already on the car so its not like I can take it off and to the store to find a few nuts. Any help would be greatly appreciated.

some dp's are hard to get onto those studs. I take them out and put nuts and bolts through. I belive they are 19mm nuts that go on there not sure of pitch though.

My DP goes right on there just need the nuts to secure it. I will start there. I ordered new ones from Mitsu just that it will take a few days to get them here. I was trying to take a short cut to get my car back up and running. Thanks for the starting point. I would guess the pitch is around 1.50 or 1.75 by looking at the threads.
