Duke Tuning and Performance

Garrett G25-660 clones.

High flow manifolds for the DTP S8. Cerakote by Stealth Hydrographics.

New Corsa extreme exhaust on this Viper ACR Extreme. Corsa doesn’t make an exhaust for the ACR Extreme so Brian Smith did some welding for us to fit the stock tips. OEM exhaust was 2-1/2” with 3” tips. The OEM mufflers also did a lot to quiet the big v10 down. Who wants a quiet v10? The new Corsa exhaust and high flow cats are 3” all the way. And they are resonators not mufflers. Sounds amazing! Now we need some good weather. Can’t wait to hear some full throttle under load sounds!

Final product looks great! Have to wait for some better roads and hotter temps to really see the results but I’m sure it will perform well.
