I called the gents at Vishnu and they gave me good news. Vishnu makes a downpipe specifically engineered to mate the ATP turbo kits with their exhaust setup. Apparently they feel good enough about this turbo kit to go throuh the trouble to make it work with their exhaust setup.

 

Great news. well I just got my car to GT motorsports in river side for clutch change, it will be ready by WED. I saw the clutch and it was such a nice pc to be installed in a spot where you cant see it again .
