Over the weekend I installed new exhaust on my Viper. I’ve been wanting to do it for years but I had to wait until I finished paying off the car to be able to afford it. After making the last car payment in January, I splurged and went for it.
It’s hard to capture the sound and especially how loud it is, but here’s a video that my friend made to give you an idea:
The old exhaust had 4 catalytic converters, 2 per side. I replaced them with a pair of higher flowing ones and that had 3″ pipes instead of 2.5″. They’re made by Random Technology.
My friend Jim was kind enough to offer both his lift and a helping hand to get it installed. Installation wasn’t too terrible but there were a pair of hard to reach bolts to remove the side sills and one of the cats was a pain to get on due to fitment issues, but overall it went fairly smoothly!
It all fit in my trunk!

Access to the catalytic converters is easy!

My dad swung by Cars & Coffee this morning with his late 1960’s Triumph TR250. I grew up riding around in it and he recently got it running again and restored. It was fun having both of our very different cars sitting next to each other, especially since his is one of the things that got me into cars in the first place! 🙂
I put my Viper on a dyno today to see what kind of horsepower and torque it was making at the wheels. It supposedly makes 600 horsepower at the crank and I’ve heard reports of 530 to 560 horsepower at the wheels, so I was curious to see what mine actually makes. Turns out it’s 533 horsepower and 504 lb-ft of torque. Considering it was a little warm out and decently humid, that’s not bad!
