XAT GS400 Lexus 1UZ VVTi test pipes

XAT GS400 Test Pipes GS430 UZS160 UZS161 Decat

Please note due to draconian laws, we are not able to ship these to a California address. Please support the RPM act.

In house custom made bolt on UZ test pipes! These are confirmed as bolt on replacement GS400/GS430 pipes, and very likely fit a number of other 98+ UZ cars as well, though we have only confirmed fitment on the GS400 and GS430. We will add confirmed fitment to this listing as we confirm what other cars these replace. Price includes both sides for installation on 1 car.

  • 3" stainless steel
  • Stainless flanges
  • Both pipes included
  • 100% bolt on!

These are for off-road use only and are not meant for any on-road vehicles. Buyer is responsible for obeying all laws, local and federal.

You may get a check engine light/MIL/CEL code with these. Gaskets/hardware not included. We strongly recommend using something like permatex ultra copper to provide a better seal, rather than going through a number of aftermarket poor quality gaskets without luck. This is what we do with all of our own vehicles, and we have found the seal to be much better that way!
