Tried the install today. Everything was going smoothly until I got to taking of the heat shields. I could not, for the LIFE of me get the exhaust manifold heat shield off. I did get the downpipe on off. The upstream O2 sensor was a piece of cake with PB, a tire ratcheting torque wrench and about 2 feet of extensions (lol) came right off. THEN i was trying to get the 3 bolts connecting the DP to the turbo and rounded the bolt head of the top bolt i put the whole thing back together and have to retry after I get some bolt extractors. To confirm, the 3 supplied bolts with the Depo DP are for the turbo end or the cat back end (please say turbo end lol)
