honestly, the AR DPs with race cats mellowed out the sometimes drone and tinny sound of the Eisenmann race exhaust of our car - seriously, it made the sound much better than it was with just the Eisenmann; even my sweet wife commented on the improved sound quality
I was worried about the sound getting worse but that improved significantly as did the POWER!!! |

Thought I'd bump this thread. Starting to think seriously about some mods for the Z and am toying with the idea of just putting catless DPs on and keeping the remainder of the exhaust stock.
How significantly do they affect the tone/volume/drone? |

Yea but only when I ran the original stage 1 tune, which throws code for catalytic converter efficiency below threshold, to be expected really with the catless.
After the Stage 2 tune I've been running for 2 week without issue/code. Thanks Vintage!

AR design has a couple of sound clips on youtube with the AR catless. anything with n54 stock exhaust should sound pretty similar. Cold start sounds much louder than this video. I think the car is warmed up in this vid. I'm running Cobb tuning Access port, Stage 2 tune.
