Has anyone or know anyone who has these on their Viper? My buddy is wanting to put Triples on his Viper and he was looking at these but we were looking for opinions on them or if there were better ones out their.

Thanks
 

IMHO aaens are the best...easiest to tune....least peaky and one of the quietest for sure...I have a nice set for $425.00....also...have a set of mega power heads....very recommended for any piped viper...much more cooling....they sold for 500 originally and arent made any longer...will sell for $325.00....then all he would need is a rear cooler.
 
Well the reason we were looking at Simons is because they don't lay over the mag side cylinder creating excess heat. We looked at PSI and Aaen's, I'm sure they would work but Aaens only lists for 02-04 and his is an 06.
 
I have a buddie thats has them and i was very impressed. when i first heard the sled i new it wasn't stock, (because of the sound of the sled) and it wasn't loud at all, I have an SRX with a bender can and it is a louder than his. If you ride in a place that requires you to have stock pipes you could get away with these and when you open the hood man it's pretty. My 2 cents :yrules:
 
How do you like your bender? I have MBRP on both of my SRX's and I love the sound on my 02 but because of porting diferences from 98 to 02 my 98 doesn't sound as aggressive. Thanks for the input so far guys, buy the way you wouldn't happen to have a sound clip with the CPR's would you? He is woundering what it would sound like. The only Viper I've heard with pipes were SLP's.
 
I've had both CPR's and Aaens. CPR's seam to produce a little more power and are a little louder than the Aaens. Installation of the Aaens is MUCH easier...the only change you have to make is to relocate the right side hood strap. With the CPR's you need to remove one of the tunnel braces and reshape it to allow clearence for one of the pipes (pain in the A$$). I'm sure the Aaens will work on an 06' mountain Viper.

Viper wasnt made in 2006. The last one produced was in 2004! I know about simons/aaen pipes. Your right that the aaen is laying over mag side sylinder but this doesnt cause any problem! You will have more problems with the simons! You will provbebly burn some exhaust valve wires and the simons also have crack problems..

You will loose bottom end with tripple pipes and the engine will be very sensitive temprature is changing..

You will also notice a terrible fuel/milage with tripple pipes.

I recomend you to leave it stock!

You might want to double check that statement. I know this because 1 my dad has an 04 Mounain Viper, and in 05 the put the same ski's thats on the 05 RX-1 Mounain and 2 I've seen the registration and it says 06 Yamaha.
 
I got cpr Hauck pipes om my Viper -02. The sound is very good, not screaming like other pipes. 31 hp also, and thats moore than with the Aeen pipes.

If you look around and see Dyno-test for yamaha snowmobiles, you see that Aeen always has low HP on yamaha.

I think that SLP and Hauck is the best pipes, then comes Bender.

Sorry I also should have mentioned it's a Mountain Viper.

I know I'm new to the site and I'm not looking to make enemys but if you would have read you would have seen that I forgot to mention it was MV and yes the last year for the VIPER was 04 but we are talking about the Mountain viper please try and read everything before you start making statements and not knowing all the facts about the thread.
 
I have run aaen's and simons. The simons to me feel a bit more peaky than the aaens. Simons are harder to install and are heavier. Aaen's are very light (thin walled) so it is important to keep good coating on them or they will rust/wear through. Aaen's are probably a bit easier to tune. Both are WAY better than stock.
 
I ran CPR/Hauck pipes and loved them! Highly recomend aftermarket heads or the CPR head mod, also a rear heat exchanger would be a nice addition with anybody's pipes. Even a stock Viper IMO is undercooled.

If you choose CPR's you will have to modify your left hand front bumper brace, I actually have one already done if you want it simply cover shipping and it is yours.

Thanks
 
also your mileage will be somewhat lower...it's more based on the accuracy of your clutching ,type of riding and how you use your happy finger...Aaens are much easier to tune with a broad torque band , sacrificing a few ponies at peak...but thereby making them less temperature tempermental....as to the debate stock or not...here's the dyno results on a 2002 stock with only carbon reed petals...119.5 at 8500 hp vs an average of 146 hp from 8500 to 9250 rpms = a 750 rpm tuning range and broad useable torque (with a 148 hp peak at 8750)
I have ran Aaen pipes for over 10 years on about dozen sleds and have never had a failure...(knock on wood) to my knowledge he was the first to build aftermarket expansion chamber pipes for snowmobiles....he doesnt sell you Sh*t you dont need or inflate...he's a straight guy...rare with performance stuff
 
also...there is a greater reason for mag failure....when the ventlines are dropped and the fuel pump fix (on 2002's ) is done...IMHO there's still a inherant design flaw with them water rail into the mag head( adding a larger rear cooler helps with more coolant....not better flow to this head)and the ability for the coolant to "turn" into the mag head...maybe it's cavatation or a "quiet" spot at that bend,but it's easily fixed
by welding a small about 1/2" piece of aluminum into the water rail to direct more coolant into the mag cylinder...
 
as to the dyno who's low and who's high in horsepower is interesting...
I'm sure we could hear from a few guys that have extensive experience with dyno's and the results......from the little I know...it's very easy to do "cold shot's" and tweak the results cause after all...we are all pay "x" dollars for each horsepower right...so if one guy is giving you realistic numbers and another gives either unrealistic or peaky
figures...you'd focus on the number...not a dyno graph...which can be tweaked as well.......it's the integrity and honesty of the person you deal with that matters with this Sh*t....at least that's been my experience....and IMHO he is tops in that!
I think it would make an interesting ty poll....who's the most fair, honest aftermarket tuners? that might be a good way for them to know they have a score to uphold...kinda like a feedback...what ya think?
