Explaining to him how the biggest power restriction on his car are the primary catalytic converters, we introduced him to the newly released Evolve Automotive Test Pipes. These test pipes are a bit unique compared to the competition because it features a very nice slip-on flange. We chose this method for the sake of assuring no risk of exhaust leaks, loose connections, and ease of installation.
In addition to this, he expressed his concern with getting a CEL from the catalytic converter delete. He also really appreciated some of the neat features that we had with our tune. To really refine the power output from the Test Pipes, he decided to move forward with our Stage 2 Tune as well.

Raised RPM Limit to 8500RPM

There is no denying that the Evolve Test Pipes add a tremendous amount of power throughout the whole powerband. There are portions of the powerband with nearly 25whp/wtq gains! Not bad for a $450 piece of hardware. With Evolve's Stage 2 Tune, you can see how with the combination of fueling, ignition, and VANOS timing, the top end really comes to life.
In our opinion, this is the 'best for your buck' for the S65B40.

Definitely quite the difference in free flow.
Getting everything all lined up.
Perfect fitment right prior to bolting everything back in.
Strapped onto the dyno for some pulls.
