I'm running with the Perrin, and would recommend it. It does require the simple installation of a relay to trick the O2 sensor. If I would have known about the UR, I would have gone with that. Why wire another device into your system if you don't have to? The Perrin will fit almost any setup. I don't know about the UR, but that sounds like the way to go! My only question would be whether the UR comes in a 3" diameter or is only offered in a 2.5"?

 

Just get a test pipe that is 3" and straight..... Then run a Auto zone special O2 sim. Basically it's 2 Anti Foul plugs with 1 of them drilled out. Look in the search and you will find what it is. Very easy works great and dirt cheap. Can't beat that.

 

ok a couple questions, Any one use the UR 3" tp and dp if so any cel light?......i too am going to get the greddy Ti and was wondering are there any full ti dp's and tp's....id like to have a full Ti turbo back 3" system.....?

 

Yep, I've got the 3" UR test pipe. It fits up nicely to my 3" downpipe and 3" catback.

 

DjRiice,

Helix makes a Ti test pipe. Haven't seen any Ti DPs yet.

 

Sweet. In that case, why not go with the UR? It beats doing the extra work of installing the O2 Simulator.

 

The WORKS one is resonated to cut down on all the extra noise that comes with removing your cat. It will through a CEL if you don't do one of the tricks above.

 

I have both the UR test pipe and downpipe and wouldnt trade them for anything. The DP fit well and comes with a flex section.The TP is great quality as well. NO CEL and I have been using them for 20K. I highly recommend these products Go get em' and have no worries. Daryl at UR will take care of you on customer support as well.

 

UR 2.5", great stuff.

 

I have the Perrin Test Pipe, great quality and fitment. Also have the perrin downpipe which is an awesome piece, I also have it jet coating, nice.

 

I have a full 3" UR turbo back w/ there high flow cat and I get a CEL all the time .

 

Have you contacted Daryl about this at UR? I am sure he would want to know and would do what it takes to fix the problem. This exhaust ROCKS!! I have the full TB as well.

 

jj08 - hav you scanned the ecu to see what code you are getting?

 

I get the P0420 cat not working code. Don't get me wrong, I love the exhaust. IMHO, it is one of the best on the market.

I just haven't had time to call Adam@Z1 or Darryl.

 

I got the UR 2.5" tp, looks ugly but doesnt matter. Havent installed it yet, but I might today.
