Ultimate Racing Test & Downpipe Review

Parts arrived quickly from Darryl @ Ultimate Racing, were packaged nicely.
I went with the resonated testpipe and downpipe w/ wideband bung.



Welds are awesome, the craftsmanship looks top notch. And also they are much lighter then the stock pieces.

Pre-install (2 weeks ago) I installed my ETS Dual Exhaust. It is loud, deep and mean.
Now that it is mated with the 3" downpipe and resonated test pipe it is much deeper, and isn't quite as loud on the high end. The rumble of the exhaust can be felt from the driver seat.

If you look at the UR testpipe you will notice an angled O2 bung, there solution to a CEL. So far, I have not gotten a CEL.

Installation

To remove the Downpipe, you must remove the stock cross brace under the car, two 12mm bolts, and two 14mm bolts.

Now getting to the spring bolts of the downpipe are a nightmare!
I used a half inch rachet, with a swivel, 4" extender and 8" extender. The bolt on the driverside was quite easy, you can see it and can aim the rachet in and get to it. The passenger side proved to be quite a pain. I found it helpful to have an extra set of hands working above holding the socket in place.

Removal of the 02 sensors on the stock cat and downpipe required quite a bit of elbow grease to get out.

Testpipe was straight forward.

Parts cost $458 shipped, and are well worth the price{thumbup}

 

This is one of the few mods I have on my X.
