2006 Coupe - I love this car! Just installed ARH stepped headers, a Roe Racing tune and throttle body, and Woodhouse Engine Mounts. I can't say enough on how quickly each of these vendors responded to my questions - and I asked a lot before bought anything, especially Sean at Roe - I'm sure he's cringing at the thought of my next round of questions. This is my first Viper and I'd have to say it is a true pleasure to work on. Maybe I just love the car but everything is accessible, removable and makes sense. The headers fit beautifully - Nick at ARH was a great help, parts arrived quickly after ordered. The car already had Corsa mufflers, but now Sounds awesome. I no longer miss my 440 Charger. That's it for mods this year, I want to drive! First dry Weds night I'm not working it's going to the track for a couple of passes.
