2008 question around performance mods

On top of that you need to get the Mopar Venom controller

With the headers, it's when, not if they will throw a CEL. Before going to emissions testing you'll need to, swap out the controller to the stock one, then clear the codes, then do the correct driving cycle so that the emission system reads "ready". You must drive the car with high RPM's and don't lug the engine or you'll trip a CEL Good luck!! Mike

 

I have been able to get these cars to pass the emissions monitors with the stock controller. The upstream O2 sensors need to be relocated to collector, a CA approved or secondary production catalyst used and the downstream sensors mounted behind the catalyst with proper shielding.

 

Hi drasch21, I recently put on a full Belanger exhaust on my stock 08 with stock controller. I have about 500 miles on the car without throwing any CEL/MIL.

I would be happy to discuss the project.

 

Go to see Steve Hemann at Hemann Automotive. He's on Jeffco, north of Richardson by the train tracks and Arnold police station. He has three Vipers himself and takes care of lot of the StL Viper people. He will tell you what is needed in Jefferson County.

 

The cars later in the 2008 model year run did better with those mods.
