"you got an elbow gutted out ?"
Nope, the TMS downpipe has the O2 housing built into it. The TMS downpipe bolts directly to the turbine housing, eliminating the stock elbow. Suprastore advertises a 20hp gain with an HKS dp and the HKS doesn't replace the o2 housing, you must use the stock one with it, so the TMS is obviously better. Plus the TMS is 3" mandrel bent stainless steel. I love stainless.
Kuban, remember turbo oil pipe nuts should only be torqued to 9 ft/lbs. And make sure the mating surfaces don't have any old gasket material left over, which is very hard to do since the studs get in the way of cleaning the surface.
