URD- Underdog Racing Development- Power extractor pipes/ rear o2 simulator

BE CAREFULL What happened to this company? This company is not what it used to be! Recently purchased the power extractor pipes and rear o2 simulator for my 2020 TRD off-road. Had a horrible experience getting tech support to answer my initial questions when purchasing these parts. Went ahead and purchased and installed the power extractor pipes on my new Tacoma. Fitment was good and install was clean. Started the truck tested for 4 weeks. Power was actually decreased! Truck sounded like crap. Check engine light came on as expected and disabled my cruise control and some other features of the truck. Finally got ahold of tech support and was told to order the rear o2 simulator to fix the problem. When it arrived I received 4 pages of instructions to install this part. I had a huge problem after reading instructions as they required cutting the factory wire harness and soldering in wires to make the rear o2 sim work. Returned the brand new unused part at got hit with almost a 20% RESTOCKING FEE on top of having to pay shipping both ways. I DO NOT RECCOMEND THIS COMPANY.

 

What did the dyno numbers show before and after?

 

Interesting. This is a mod I was hoping to do shortly. (No emissions testing in Canada)!

 

I recently met up with a person that had Doug Thorley headers. I flashed him with an OV Tune and took care of the CEL issue.

Maybe check around for local person that could do the same for you?

First post?

 

I don't know much but their return policy seems pretty standard for most retailers.
