Just picked up a blown viper er. Has CPR pipes. Also came with stock exhaust so I'm thinking of swapping back to stock. Anyone ever run these pipes?
Good pipes. Make great power.

They are awesome and get your attention. Your arms tend to get longer during the season HAHA!. They do cut your MPG way down to about 10mpg and require you to run at least the opticool headgasket and rear cooler. Head mod is best but can be run and very reliable. Highest octane fuel will help also. I loved mine and miss them, wish i still had them.

I have them, ran one season on the trail, last season my sled was retired to the weekend bush bomber. The pipes make ridiculous power. Sound absolutely amazing. Jetted to the air box I found to be not super sensitive to temperature. I am running a rear cooler. Completely stock 9000 mile engine. Pulling sled lengths on sleds priced 4-5x much as mine. I'd keep them.
A couple of bucks

Here's your chance. He's putting the stocker back on and you have first dibs on the CPRs.
Really great pipes and you can still call CPR for info if needed.
