Hiya,

Well, I finally got my bike back after having had cams (s&s MR103 easy starts), pipes and and RSD AC installed. My engine tuner did a pretty good job working with the sub standard pipe I supplied him with. Straight out of the box, the V&H Hi-output full stainless system cost me 30 lbs/ft of torque. I really stuffed up here. I was going with the usual route with a set of Power Duals, but changed my mind at the last minute after viewing a couple of YouTube vids. Should've done more research.

These pipes would suit a 120R with 640 lift cams. They have next to no back pressure.

As you will see from the dyno chart below, we ended up getting almost identical peak figures to the factory chart. Brian had some custom full length baffles made, which are also packed in fiberglass. We also installed a set of torque cones. Not ideal, but far better than the loss of torque it had at the start.

I'm pretty happy with the way it goes. Has quite a bark when I'm on it, nice and quiet at constant throttle.

Also had a set of Ohlins fitted to the rear. Man, what an improvement over stock! I never noticed how much the front end clunks before. Should have that cured next week when the premium ride front for inserts go in, along with the chrome fork legs.

Those pipes sure look cool. It's too bad that they lack in performance so badly. If V&H built a set of those pipes in a better performing configuration and I'd be running them.

I don't know what the difference is between the stainless version and the chrome but I am getting great performance out of mine on my 110". I'll do some research and see if it is a more free flowing system than the Black or chrome. My dealer here sells a lot of this set up and gets great performance out of them.

Those pipes are designed for 110 engines or larger and we're never intended to be on a smaller cubic inch engine like the 103 or 96". Also there website also states this fact that "these pipes are designed for larger cubic inch engines"
Dealers don't read up on what they are selling and sell whatever will make them money!

The difference is the stainless version has a stepped header that goes from 1 3/4" to 2" at the mufflers, and the very open baffle in the mufflers is stepped as well, from 3" to 2 1/2". This results in a system with very little back pressure that is way too loud. My tuner says it was louder that a set of short shots.

So are you referring to the stainless version? Several of my riding buds have the chrome or Black version on their 103's stage I and their bikes run great. I know a lot of people like to hate on the dealerships but I know the one I use does a great job. Well I will say there are at least a couple of mechs that do anyway and I am sure there are some exceptions.

Ok I just went to the website. Now I understand as this is a completely different setup than the Blk/chrome Power Duals with HO pipes. Cost reflects it too!

They are a stunningly good looking set of pipes. Very well made. I'm as pleased with the outcome as I am annoyed at myself for making a last minute decision on these without reading the manufacturers notes.

My dealer was going to fit these for me with an SE tuner and a downloaded map. I'm glad I chose to go with an indy tuner that put the extra work in to make a set of custom baffles to get the most out of these pipes. After The extra work cost me $400, which seems more than reasonable since he did dyno runs with the new baffle bare, with minimal packing, with much more packing, and with torque cones. For each run he put time into the tune to get the best test result. Ended up with a fair bit of packing and the torque cones.

It's still down a bit of torque around 2,000rpm, but a little better around 3000rpm.

V & H Stainless High Output

My buddy runs them on his 13 CVO RG and it puts out 118 lbs of torgue. Performs real well on the 110.

Sounds like big bore kit and heads might be a big help!!
At least you have a great Indy guy who helped you out.
Good luck
