ZL1 A10 Fuse Pull + Cat Delete
I finally got around to the "51" fuse pull and secondary cat delete today. I have to say I finally have some exhaust sound in 9th and 10th gear (mostly thanks to the fuse pull). Before, I could feel the back-pressure of the closed valves when in auto mode when I slowly increased pressured on the gas pedal. It was completely silent until I hit 2K RPM. In manual mode, hitting the gas in 9th or 10th resulted in no exhaust sound whatsoever.
As for the secondary cat delete, I sense there's only a minor bump in sound, but only in higher RPMs. Hard to tell though. May be time to go with a Corsa Extreme axle-back to get the bump I need. |

I thought about that, but then I'd break the warranty for sure after tuning.
