Overall I'm impressed with the quality of the pipes. There was a little bit of welding slag on the inside of the pipes that I thought could have been cleaned up a little neater (spend all that time with the complex fabrication, and leave the easy stuff?). But since its back of the turbo, I wasn't that concerned. If we were talking about the exhaust manifold, different story!
The fitment was nearly perfect. There could have been a tiny bit of misalignment around the turbo fitting, but not anything that the clamp connections couldn't handle.
Its too early early to tell if there will be long-term implications of not having a flex fitting near the turbo joint (like the OEM DP's), as others have pointed out on other threads. I really do think that would have make sense at the cost of a couple horsepower perhaps? Lots of temperature gradients down there meaning lots of metal wanting to deform...
BTW: I've owned a previous Ultimate Racing product before (turbo kit for S2K), and all their fabricated parts for that never gave me any issues over 3 years of installation.
There is a thread out there (with pictures) of someone who needed their UR pipes cut and rewelded because of fitment issues, but I don't think root cause was determined (bad manufacturing v. bad install)
Hope that helps!
