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!
