Hepco Becker - got them from this STORE tab above as well.
Funny thing is that after a friend of mine rode my Guzzi with the new Megs he traded -in his Harley for a V7III Stone, and now he is ordering a black set of Megs for it. These pipes sell bikes!

Those are the nicest looking pipes I've seen, with the added benefit of making it easier to access the rear wheel.
Just put the very first set of polished GT-Rx® GP megs on a V7/50 Anniversario today along with corrected fueling. Sounds as good as it looks and runs.

Wow...I had almost convinced myself to go the brush. But Wow..that does look nice when polished!! So I may have to reconsider!

...And have pulled the trigger on the polished. Can't wait
One of my black GP production sets mounted on the RentAGuzzi Racer 820cc Mk III (stock high mount) shown below. 100% Made in house USA stainless steel.
They'll fit high or low mount V7 IIIs.

I got my GT-Rx SS Black V7III GP Megs yesterday. Amazing change - the sound and the looks hit you first. Then when you climb on the bike and pull off the driveway you instantly notice that the power delivery is more smooth and as you accelerate you just feel the torque at all gears and all RPMs. The ride was fun before but now it really is awesome. When you will finally get off the bike you will notice a huge grin on your face.

Hi all,
Had the GP Megs on for a little while now so about time I comment . When I look back at pics of my bike when I first got it compared to now, the original mufflers now just look so out of place. Can now walk around the bike in my shed when pottering without bashing into the mufflers that used to just stick out, they were massive! When swapping them out I couldn't believe the weight difference! The GP Megs suit the bike so much more. Plus they look so different to a lot of the other offerings by others for this bike, which all look very similar to each other. These GP Megs stand out, I think just look that much cooler when compared to those others. ... After getting the bike back after the first service, the service department manager mentioned the boys in the shop approved
Now the sound. I love the thumping idle. Makes me think of a hard rock drummer really giving his skins a good bashing. Love it. I also love the sound when decelerating at speed, not sure how to describe it, just that nice deep twin sound. And obviously there's an appropriate aggressive growl on throttle openings!!
These are probably the loudest pipes I've owned, so my initial thought was maybe a tad too loud. Having said that however, I thought my last bike wasn't loud enough! Now though, on the bike, hearing that thumping idle coupled with that Guzzi engine vibes at idle, can't help but think to myself "this is cool". The sounds suits the bike. It sounds like it should.
Here are some pics, hopefully give a good view from multiple angles...For more pics check out the newer ones in my flickr album:

Still on stock fueling...Have just ordered the ECU reflasher tool, just waiting for restocking before I can get my hands on it. In the meantime, I know there is a dyno graph on this site for V7 III with GP Megs and stock fueling, but are there any with GP Megs and after ECU remapping?
Cheers!

I didn't have time to do the dyno run... spent all the time mapping it. You'll simply see a smoother graph plot, with the dips filled in. That's likely about it.

Very nice pics! And thanks for the report. Would love to see/hear a video of the new pipes, if possible... thanks!
New owner, new exhaust, 1st post...
Purchased the Megs on a work trip out to LA a couple days back, installed them last night. They look and sound amazing, videos can't do them justice. The GT guys are awesome... Not to mention Todd, a very patient soul with all my questions.
For those installing themselves, I had a fitment issue on the left side. The factory system was canted slightly toward the right side of the bike. This made installing the clamp on the left side virtually impossible to fit between the exhaust and kickstand/frame section. With Todd's advice, this was easily resolved by loosening exhaust at the heads and cross pipe which allowed everything to "true up". For clarification, this was not an issue with the Megs but the OEM system.

What I want...
Todd - do you have any these you could post?
3 perfect ones would be:
1. Stock V7 III zero mods stock map
2. V7 III remap but still stock intake/exhaust
3. V7 III with exhaust mod and remap
On my V7 III Racer I am pretty impressed with the stock map & running. But I come from a world of Ducatis and KTMs that have had pretty bad running bikes (fueling map issues and somewhat light flywheels) ... like trying to maintain a steady 35 mph. So I'm sure the stock V7 III is lean, but it seems to run very well (no stumbles or hiccups, warms up quickly, etc).
I am planning for an exhaust and your remap after my first service ... but just curious how much the mapping would help a stock bike. Like would it be worth getting the mapping tool now, loading a better map in with the bike totally stock, then update the map again after getting a new exhaust on?
Thanks!

Most of your musings will be satisfied here on this thread.
I agree though, that those 3 charts would be of interest to me.
David, I suspect you might want to ride mine to see the difference. The stock setup is pretty good, for sure; better than the V7II from what I've heard, but I've never ridden one of those either stock or modified. However, there's just no comparison to how the remapped fueling works—either with just the stock mufflers and everything else completely stock, and especially with good after market mufflers. Really. 
(The 2017 Ducati Scrambler I owned for three months had absolutely the worst, most inconsistent and irritating, low speed throttle response of any motorcycle I've ever owned. And that included after I had gotten an ECU tool for it and had tried two different maps that everyone was raving about. It just sucked, was one of the reasons I got rid of that bike. Life's too short to fight with a machine like that...)
