I am also somewhat concerned about the band having stretched. I'm not sure on the exact torque that the clamp should be tightened to. I may have over tightened it the first time as the part of the clamp that the hammer type head of the bolts hooks into is a bit warped and disfigured. It still has plenty to hold on to but it doesn't look like it would as new.
I'm thinking the indexing on the y-pipe to turbo connection is just as important as over the overall alignment. Especially when it comes to the lifespan of the flex pipe. If your tilt your turbo up a bit from the mount to get the flanges to line up and tighten the clamp down at that point, it would probably put a bit of a torsion on the flex that could cause it to fail prematurely (if there is such a thing on that flex section.) I'm going to try to find the ammount of clamping pretty that will hold the sections together evenly but loose enough to allow the mating surfaces to rotate within eachother enough to relieve any torsion. Is that going to be possible or am I just going to have to take what I can get.
I had a leak and a noise in mine when I did the turbo the 2nd time. (I had reused the same v-band clamp.) You really can't index the pipe. Just loosen up your turbo bolts, and downpipe clamp, (I forgot to mention that earlier.), and install the new v-band clamp. Tighten the "y" pipe, the downpipe and then tighten the turbo bolts. Should be good to go.
