heres one for those of you who have the srx piped vipers or similar setups. my i dea is to use the 01 srx cdi box and a set of bender tripple pipes and silencers since i dont want to carve up the sled to make the stock srx pipes fit. anyone else think this would work ok? still get good power, reliable, and gas milage. ive heard about tripple pipe vipers being gas gusslers, but the srx piped and cdi box ones being ok. i thought maybee the bender pipes may be similar since they are designed for the stock rpms peak power range. any thoughts? thanks ahead of time

I would talk to Betheviper-- I believe he's done it and I think it is safer for pipes....not sure about better gas mileage, I think that comes with the SRX pipes.

the SRX box is a good idea to fix the timing issue the triple piped Vipers have, and you might not have to go to such a big main jet to cover up that problem, but dont take my word on it. It would be a lot easier putting the Bender pipes on, like you said, you dont have to cut up the sled to do it like the SRX pipes, guess its all a matter of what you can get away with, I went with the SRX pipes to avoid tickets for aftermarket exhaust.
If I had a Viper I would try exactly what you have suggested, but I don't and I have no knowledge of this setup but it sure makes sense to me!

i think im drifting into uncharted territory, guess ill just have to try it and run it against my cousins 01 srx, it was faster than my 00 srx that was really strong and usually didnt get beat. i also have a 06 nytro that runs prety close to it as it is stock right now so i will be able to compare to the 2 sleds to see how much gain i does. i also have a buddy with a viper that has v-force, bender pipes and little clutching to compare with, probably will be a while before i get to it though. guess ill have to let everyone know when snow flies,(maybee in the yard before hand) i may get impatient.
To set the record straight. I have used slp pipes, coated on my viper but only with the viper cdi box. I had underhood temp sensors on them, air box temp sensor, and after I burned it up, I bought a set of egts. I ran them for about 1000 mls and came to the assumption that, viper pipes, thought they work good , don't do what they should. I then after being told that srx pipes wont work, decided I would do whatever I had to do to prove them wrong. they fit and the key is the box. The box for trail riding is where your loosing fuel, using it to cool the piston. I purchased the slp pipes after talking to many who had run them on dynos and had acually compared them to other sleds, on timers, on dynos. They were also very quiet. I sold them, started on my quest. Looking back, I wish I had installed a srx box on my sled with the slp pipes and checked them out but I didn't.
The srx pipes worked great once I used the correct box(for an entire winter i had the viper box installed from racing and fogot to change it) and turned the EGTs off. Timing gives some weird readings when your changing timing that much. I believe the viper box has 7deg more timing at 8600 than a srx(please correct me if i got that wrong) that extra timing makes more heat in the motor and less in the pipe than the srx timing which makes your EGTs show in the 1500 range compared to the 1275 I was trying for with the slp pipes and viper box. Even when i changed out the box I still thought I had an issue. After checking everything, I turned it off and headed down the lake, checked the wash and was rich.
anyway, I have not tried the cdi box on slp pipes but I know from all my other testing what causes the fuel burning issue. that being said, you will not have the same power with the srx box. It is alot less timing and it will make alot less heat in the motor and less power. You will want to wrap those pipes, they loose alot of heat and this is what makes a motor more jetting friendly is when you can maintain all the temperatures.
You will save gas, you wont burn your sled down on decelleration (biggest problem with pipes running over peak timing curve) with a srx box.
If only those pipe makers were not looking at price, they would have sold pipes with a cdi box and pipe wrap, these two things would have made them the most popular pipe on the trail after the first year.
dont forget to install a srx base gasket when you go to pipes to even out the heat.

Let me know if you need another sled to compare it to, lol, I am about 45min-hr north of you, and if there's snow, I'll travel! lol.

maybe we can ride this year, im always lookin for snow, dont get much in my area im always traveling north towards arcade and on further your direction. your pic also brings up another part of that idea i have, the srx heads and coolant rail. rumor has it that that also helps with the cooling issues on modified vipers. anyone who has done it confirm if it does help and if it does anything powerwise? not sure how the chambers are, if it would do anything to compression or not. i wanna still run on pump gas, after all it will be a trail sled. especially with the shit gas were gettin these days.

Just put SLP'S with cut SRX heads(from BTV) on this summer and haven't tried them yet.... sounds nice though-- can't wait for snow. I used SLP jetting and also have an SRX base gasket and found a water rail like the Mega-Power rails. So I'll have to wait and see how she goes, and adjust clutching of course.

is anybody going to try this srx box on the viper this winter? i would also like to get my viper alittle bit more trail friendly also.

Can someone explain what the SRX base gasket does on the Viper? Thnx.

srx heads only need to be cut, if using a stock viper head gasket, and you don't have to cut viper cyl's to have o-ring grooves, as you can just use the stock viper head gasket, or super cool head gasket. even 1 layer of stock gasket works and then you just face .010" off the srx heads.

betheviper can prolly explain it better, but it evens out the cooling between all 3 cylinders, due to the coolant cutouts in the gasket.

correct, I cant remember why i figured they needed to be cut, my 2stroke engine building is a lil foggy from last season, I just figure might as well have all the components checked out and machined for maximum power per situation. I am also accustom to cutting the o-ring grooves from my wheeler build, we had a heck of a time getting the gasket to seal, so I use o-rings where ever I can for best seal. The sleds are a lot easier to seal.

weird. what wheeler you got? i've never had issues w/stock steel head gaskets sealing.

Raptor 700... bored out from 102mm to 105mm, 14:1 true compression, Cometic gaskets... SCE has came out with some better gaskets to solve the problem though, I just havent let go of the hatred towards headgaskets, lol.

ugh.....i HATE cometic gaskets. they have gone down in quality and really suck IMO. what piston you running in that raptor? you should have built yourself a stroker w/that thing.

yea, Cometic was the only company making 105mm gaskets up until a month ago, I blame the head gasket issues on cylinder prep (my own fault) but a gasket should make up for some ignorance, lol. And it is a stroker too, I just never mentioned it, lol, +5mm stroke
I have a CP piston in it, they are the only ones making shelf pistons that will clear the +2mm valves in the head
