For some reason I was going to install this and never got around to it. It's new in the box, I opened it only to check to make sure it had the gaskets and hardware. PM me your offers.... thanks
Some info from on the testpipe originally posted by Jeff:
Power Source Innovations Test Pipe
The PSi Test Pipe Includes:
-Fully Polished 304 Stainless Steel Test Pipe
-High Quality Stainless Steel Nuts and Bolts
-Test Pipe-to-Downpipe Gasket
-Downpipe-to-Turbo Gasket (Other manufactures do NOT include this piece)
Q: What are the differences between the PSI testpipe and other testpipes on the market (if any)?
A: The PSi testpipe is a superior value for several reasons. It is constructed entirely of stainless steel. Stainless steel resists corrosion and rust. Stainless steel also retains more exhaust energy than mild steel resulting in better performance. The pipe is properly matched internally to avoid power robbing flow restrictions that other testpipes overlook. The PSi testpipes are welded inside and out resulting in reliable product. The precision welds inside the pipe are made flush to further reduce turbulence and maximize exhaust flow velocity. The pipe is finely polished for an attractive finish. Skilled fabrication, high quality materials and attention to detail allows PSi to guarantee their testpipe against manufacturer defects.**
Q: What kind of gains should I expect with a test pipe?
A: A testpipe is a flanged pipe designed to conveniently bolt on and replace a catalytic converter section in racing applications. A testpipe removes the exhaust system backpressure caused by the catalyst increasing the efficiency of the turbocharger. It is this increase in efficiency that results in power gains. A vehicle with a testpipe will make more power at the same boost pressure as well as allow for higher sustained boost pressure and faster response than a vehicle equipped with a catalytic converter.
Q: What is the diameter of the PSi testpipe and how much power does it support?
A: The PSi TP uses a 2.5" I.D. (inside diameter) pipe which will provide sufficient flow for up to 450bhp (brake horse power). Our testpipes were designed with the common application in mind (K03, K04, and the GTRS+ Series). Users with larger turbos will expect to see higher gains up to 400-450bhp.
Q: So I have a testpipe on my car now. Will I be able to smog the car?
A: A testpipe replaces the catalytic converter in the exhaust system thus causing your car to fail smog. It is designed for off-road racing applications and thus is generally not allowed for use on a public road. This is enforced by local emissions inspections in some areas. Please check with your local regulations.
Q: Will this testpipe give me a MIL/CEL (Check Engine) light?
A: The installation of a testpipe will result in a check engine light that will indicated catalytic converter failure. This is because the engine computer is seeing no activity from the catalyst since it has been removed. The check engine light will not affect vehicle performance, reliability or longevity. Some of the earlier OBD-II MY models can bypass their MIL/CEL with a use of a spacer and/or resistor tapped at the secondary O² sensor, which will keep the light off. Later models have their own Readiness tests embedded in the ECU, that will pass or fail smog internally, thus throwing a MIL/CEL regardless. There are some software companies that give you the ability to disable the MIL/CEL. Due to many legality issues, many US-based software/tuning companies will NOT tamper with the MIL/CEL. Check with your local tuner. Otherwise, the MIL/CEL should not and will not affect any tuning done in your car.
