I've been wanting a Viper for a few years now and this one just popped up at an odd time and had to jump on it. I'm the 4th owner of a 1999 RT/10 that had 29,400 miles on it.

Want to upgrade wheels, rear brakes, see if I can get the A/C working better (found some old threads about vacuum at WOT, and may need a proper recharge), and in the future get some performance work done (cams, heads, high flow exhaust, tune). This is my first viper and it's taking some getting use too but it's an exciting process thus far. Got it yesterday and have driven it close to 600 miles. I love driving this thing but it's so damn hot right now in South Texas I'm sweating before too long. Have yet to take the top off but some day I will, soon.

Congrats! You'll love driving with the top off. If it still has the stock cats in place, cut them out now. It will reduce the heat by 70-80%. I think only 549 RTs were built in 99, I got one too. Best year evar :D

Curious, just cutting the cats out wont yield engine codes or fail exhaust emissions? I'd like to reduce the heat but not if I'll end up failing emissions tests. This Viper actually failed an emissions test with the last owner but then subsequently passed a week or two later as I found out via carfax...perhaps that owner had the same idea? Thanks for the info though.

Not a great idea to cut the cats out, as the smell is not pleasant , but more and more it is getting to be an issue for trade in in many States. Get some high flows maybe, but enjoy your car and decide if it is even an issue first?

I would strongly recommend high flow cats rather than the stock cats. They are lighter and improve flow and the sills don't get as hot.

I am in Alabama, no need for nasty cats. Sounds obnoxious too. :D


High flow cats are a good compromise, but it will still retain some heat. Beautiful either way.
