Any one run or know of any one running a 4 bolt turbo on a TTA? I was all set on switching to a 4 bolt exhaust housing on my T63E. The problem is it looks like I'll have serious down pipe issues I would have to overcome. 
The no brainer thing to do would be to forget about the idea. The more I look at the ATR down pipe the more F'd up it looks. That is one sharp bend the exhaust has to make right there at the turbine exit. This makes me more determined to come up with a better set up.
