Honestly it's not worth spending more than $100 on. I bought a berk because of the price and the cel fix. Just make sure you keep your cat. because if you ever need to sell your car or move or what not you will deff need it.

Here's one of the other big differences in the way our test pipe is designed vs. the way the rest of them are designed.
The stock location of the O2 sensor is fine when it is in a stock cat or when you are not using a mechanical O2 simulator. The O2 sensor does not hang dangerously low and it is tucked up high enough not to hit anything.
When you put a mechanical O2 simulator on those test pipes with the stock O2 sensor location, the O2 sensor is pushed further out and the entire sensor assembly is actually pointed towards the ground. There have been a few isolated cases of people who's O2 sensor's were ripped out because they hit something or their O2 sensor caught on something. One guy was unluckly enough that he happended to have a titantium exhaust and his O2 was ripped out. Good luck getting that one repaired.....
What we do different......
The position of our O2 sensor is positioned in a way that does not effect the ground clearance of the O2 sensor. Our O2 bung location is actually placed higher than stock so that the O2 sensor is not pointed downwards. Which leads me into the second point.
We made several prototype test pipes with heat sheild brackets but it is impossible to do unless you keep the O2 bung in the stock location. You cannot "rotate" the heat shields because once you do, they begin to interfere with the OEM spring bolts and/or the 3 rear bolts of the flange. The only way to get the heat shields to fit properly AND have proper ground clearance is to trim the heat shield. This was deemed unacceptable for us to require that you modify a stock part in order to install one of our parts.
So in the end we opted to go with no heatshield tabs vs. an O2 sensor hanging dangerously low to the ground.
Hope that all makes sense.
