You'll learn over time how to control the low-speed lunging. It takes a delicate touch and minute adjustments. And you can always just push in the clutch to stop it before it gets too obvious and makes you look like an idiot.
If you install the 3.55 gears, you'll never have skip shift interfere with your driving again. In the meantime, and in the future, simply go up to a higher rmp before shifting. You should anyway. It's a common problem with newbies that they shift too soon. We've all been there. I don’t think you’ll need the skip ship eliminator, but if you do, JonB at
www.partsrack.com sells them as cheap as they come, and everything else Viper for that matter. When I was a newbie, JonB talked me out of the skip shift eliminator for the reasons stated above. He was right.
Your dealership Viper tech may not have time or a lot of experience installing aftermarket exhausts, given that most of their work is warranty or stock parts work. (There are of course exceptions, like my tech.) If you don't want to do the work yourself and if your tech isn't one of the exceptions, I would think a Viper tuner would be the best bet (if you have one close), since he'll have experience installing Corsa on Vipers. My next pick would be a tuner for another performance line, like a Porsche tuner. Finally, a reputable and skilled muffler shop might work too, so long as it's not just a chop shop. The side sills on the GEN III are a real pain to get on and off, even for the experienced, and getting the Corsa tips lined up just right in the side sill exhaust holes has proven to be a real pain as well. I wouldn't trust this job to just anyone with muffler experience.
