I have a master powers gt45 and a 3 inch downpipe, both with the vband clamp and both measure 4" dia. When I go to put the clamp on and tighten it down the downpipe is loose no matter how tight I can get the nut on. It looks like the turbo side has a shallower "backside" where the vband clamp actually rests onto. Has anyone ran into this problem and if so what was the fix? I'm trying to work on my car today and hope to get some shit done. I feel like I should know the answer to this one.

 

after looking around I think I came across my problem. I think that they are 2 different v-bands that I'm trying to match up (one came on the turbo, the other is from my BG turbo kit). This might be a tough thing to fix as I don't think you can purchase just the flanges. shit.

 

i have a single collar, i only needed 1/2 from a kit, but like you said you cant buy just one. if you need it send me a pm.
