Who\'s put 2000 headers on their 96-99 Viper ??

I'm going to install 2000 factory headers on my '96 GTS tomorrow and I want to know if there's going to be any surprises.
Is it a direct swap and bolt-in ?? I'd just like to know before I get into it, and bring anything needed to make this hassle free as possible.

Thanks !!!!

FYI...You're gonna need shorter bolts...Yours are too long...Don't forget those bellville washers too...Just order 2000 bolts and washers from the dealer, if you wanna be sure...Order 10 bolts that DON'T have the heat shield extension thingy on them...will look cleaner than mine, until I change them out...

Hey JH, I just did the swap out, among other things in the past two weeks, so it's all fresh on my mind, lucky you...

If you do not have a 98+ flex pipe section (one piece section per side that attaches to the headers at one end, including the cat and then bolts to the rear resonator section) then your in trouble. I have heard you can chop off off your OEM section and weld in a flange that will line up to the newer header but have not seen it nor talked to anyone that has done it. Would be all sorts of fittment issues as a flush fit is a must obviously.

If you don't have the section I recommend getting them, bottom line. Other than that the OEM heat shields will transfer over to the new header with some bending and prodding.

Make sure to use new header gaskets (Tators for me), and the OEM header bolts will not fit, too long. El cheapo fix is too triple washer them out. Correct fix is 98+ header bolts (or SRT), maybe 1/2 inch shorter. If running heat shields make sure to get six of the shorter style (98+), or just triple washer out the six heat shield bolts.

Any Q's shoot me an email, or call, it is a little work, the fit is tight to say the least, ,I didn't pull my valve covers as some do to avoid scratches but did pull quite a bit of engine goodies and it was still a tight poke to get them in.

take care,
Ryan

So what you're telling me is to wait until I have the newer header bolts from the dealer, and find a pair of flex pipes from a '98+ Viper before digging into this project ?? Where might I find a pair of flex pipes without going new ?? Most people sell the entire exhaust system if they get rid of anything.

What about POWER , did it help ? Or is it just a weight savings.

Sounds like too much work for stock headers IMO. Time to just pick up a good set of aftermarket headers.

Hey Gang,

It's not that big of a deal, I yanked OEM end to end with my brother not knowing what I was doing in 90 minutes, headers to tails.

Install was about the same, trick is having all that you need and not hanging on parts!!

As for power, my VCA dyno day is next weekend, I will let you know the gain from my baseline dyno at the same facility last year.

Personally I think there is some power there, Janni and Henri Cone hit 450/500 on a stock 96 GTS with 98+ headers and cats, and a catback. That seems a little high considering, strong car, or did the headers help, both?

Time will tell, I was 421 SAE last year, will post the new numbers good or bad.

If in the next few weeks if the OEM rear muffler sounds too tame for my liking, it's history with a X pipe and then have that section jethot coated as well, at that point my ENTIRE exhaust will be coated from header to tailpipes. Should help with EGT temps and side sill heat, etc.

If that happens, (and from early garage runs it looks like the muffler is going to go, not much louder at all with the headers and Roe Ovals over my OEM garbage), I'll go dyno again to lay to rest the rumors of 2 horse gain from rear muffler delete up to around 12 I think was the highest I read on the morgue. My only regret will be both header upgrade and cats at the same time, so I will not be able to confirm the gain independantly.

Just came in from a few hours of putzing, snapped a SS band clamp on a 1/4" drive with one hand, not good. Much as I'd like to think it's my latest gym fad, I don't think that's the case.

JH on your threads about exhaust your post states your looking for the resonator section. In my book that is the section AFT of the one your looking for. The resonator section connects just aft of the cat, and includes the resonator and then curves into the middle of the car, connecting to the rear muffler. Making sure we are on the same page as you would find the resonator section more easily from any catback upgrader (ie Corsa) as they come with their own versions.

Take care,
Ryan

I too installed a set of '98 tubular manifolds in place of the cast iron units on my '97. On the '97, the headpipe connects to the manifold with a bell connection beld by two bolts. The '98 manifolds have utilize a band type clamp that wraps around the manifold. I got the manifolds & headpipes very cheap (barely) used, that's why I did it. Don't know about power gains. I have read that it's only 5 hp.
