Later this week probably Thursday night. But, we are aiming to get it all done in one shot. In the following order:

1) Stock (Baseline)
2) TDX cat back
3) TDX cat back w/ high flow cats
4) TDX cat back w/ resonated test pipes
5) Possibly- stock cat back w/ high flow cats
6) Possibly- stock cat back w/ resonated test pipes

We will get 3-4 runs with each configuration and take the average of each one. Not low stock and high cat back, that is inaccurate and it is false!

It is a Dynojet and it will be set in SAE all the way through.
The only change we will make will be the component we are testing. I will take video and sound clips as well.

I welded a wideband bung in to the stock exhaust to show all of you what the A/F numbers will be stock. I will also have A/F readings in every other configuration to show you if it leans out and how much.

Stay tuned...
