Welcome, ssssnake!
I'm in Irvine, Southern Orange County.
I never knew how much I liked Vipers until I bought one.
Its such a radical, unique, outrageous car. It has been a very satisfying experience. At 9000 miles since new, it has been a blast.
Now that I am used to the power, all I want is MORE! Isn't that sick?
I would reccomend the Corsa cat back, it sounds great, and its a little louder, but in a "growly" kind of way. I don't hear the UPS truck "putter" now, or any where near as much. Lowers the typical stock exhaust interior resonance at lower rpms, too. (It does both at the same time, somehow) Corsa has those fat looking tips, too. Looks great, sounds great. Some people say the Borlas are just too loud, and make your head hurt. I dunno, I've never heard them. But I guess you would have to drive the car for a while, before you would really know about that.
A skip shift eliminator will eliminate wrestling with the ever-popular and endearing 1-4 skip shift feature. I used Northwinds', and it took me 15 minutes to install, very easy.
I'm tall, so I installed a Northwind seat lowering kit. I probably took twice as long as typical, maybe two hours or so, but I was just shuffling through it. Now I can see the traffic lights without ducking!
Next up will be maximum fun for the bucks, which is 3:45 gears.
Save your old gears, if you are gonna go wild mod on the car, 'cause later you will just spin and spin off the line, and you may wan't to put your 3:07s back in.
Next best fun/money ratio item is a lighter flywheel. you probably noticed by now that the Viper engine has a huge flywheel, that takes time to "spool up", (and down), which makes downshifting kind of, um, "lerchy". A lighter flywheel won't improve 1/4 mile times, I'm told, but makes the car easier to drive, and its less anoying than having this huge flywheel to spool up and down. (So I'm told, but this sounds likely, based on my "feel" for the car) Use the search button on "flywheel", and you will find a plethora of mostly vague uniformed questions, and a wide variety of opinionated answers and driving impressions. But that's just my take on it. Make your own determination.
The Viper techs are an indisposable resource, and the ones I know are Dan Cragin, and Dave Jenkins. Daves' number is 949-788-6335.
Hope to see you at the VCA events! Cheers!
