I'll soon be offering new designs of the GT-Rx® exhaust systems for the Griso 11/12 per below. This includes the connector and new style trapezoidal muffler as shown, to replace your (often cracked stock) Y-pipe and muffler. Available in Ti/Carbon as shown, or full Carbon/carbon.
Connector pipes are in stainless (only). Price will be $859.95 for the Ti/carbon (as opposed to separately: Y-pipe $369.95 + muffler = ~$1000-1200) --OR-- Carbon/Carbon for $959.95.
The GT-Rx right side (shown below) with long Ti/Carbon muffler is $1099.95 (short muffler or long), and $1199.95 for either in carbon/carbon.
Fuel modifications are highly recommended, and the NEW Right-side* exit under body (below) is mandatory for my GT-Rx ECU re-flash (only). Full 2-1 system coming in a few months.
Comments/questions? Contact me direct e-mail; Todd at GuzziTech.com if you're interested in ordering, or I'll get them onto the Store (tab above) when they are in stock.

w/db killer: ~89db @idle, 96db @3k RPM .
w/o db-killer: ~93db @idle, 100db @3k RPM.

Right side Underbody (GT-Rx ECU re-flash only/mandatory) - $859.95 (+$100 as shown below):

Re: New Griso GT-Rx™ Offering

I'm interested for my G12 but with a question. Any expected differences in bike tune given exhaust pressure requirements for the 8V? Not forgetting I'm running the full GT-Rx ECU/PC-V. I'm not after more power, just want my bike to run well.

Mark, this system would come with a db-killer for the quoted price, and I suspect will run well on the G8V with my full kit. I'll try to slip it on an 8V with my fueling mods and give a report if you are interested enough to put a deposit on it.
 
Re: New Griso GT-Rx™ Exhaust Offering

Wow that looks nice . . . similar to the shorty double Termi for the Ducati Diavel. I hope it goes into production.

Indeed, and $2600 cheaper!

This one is available for sale (one of one in the world), and next up is a full system, under the trans version, exiting right side.
 
Re: New Griso GT-Rx™ Exhaust Offering

Damn you Todd...just when I thought I was done spending money on my Griso ;) .
Was contemplating this weekend how good a short trapezoidal exhaust would look on the Griso after "admiring" the Akrapovic system on a friend's BMW. I am definitely interested. May be a fire sale on used GT RX exhausts if this goes into production :lol:
 
Re: New Griso GT-Rx™ Exhaust Offering

Nice pipe - looks like I was a few months too early. Do you have the dB at idle and 3k rpm for the existing right side?

If you drop that new one down to 94db @3k rpm it would be at least noise legal over here.
 
Re: New Griso GT-Rx™ Exhaust Offering

That looks really nice. I think, I'll go for this one. Have to wait until after Christmas though.
 
Re: New Griso GT-Rx™ Exhaust Offering

Looks great; would you be able to post a photo that shows the whole bike?

Thanks!
 
Re: New Griso GT-Rx™ Exhaust Offering

A very nice looking exhaust. I have just started talking to Todd about my 8V Griso. If anyone out there wishes they had or could get one of these new exhausts but need to sell their used GT-Rx system I might be interested but I am in the UK if that causes a problem.

Thanks Eddie.
 
Re: New Griso GT-Rx™ Exhaust Offering

I received the prototype system from Todd on Friday and was finally able to install it yesterday evening. As with the original GT-RX exhaust, the quality is top notch. As expected, the fit is perfect.
Since I eliminated my passenger peg brackets, I fabricated a simple mounting bracket that has the same "contour" as the backside of the passenger bracket.
I am very happy with the way the system looks, but more importantly LOVE the way this system sounds :woohoo: .
I am currently running it sans db killer. The original GT-RX pipe sounds great, but in my opinion, this set up is even better. Louder - but not intolerably so - if I get to the point that it seems too loud, I'll put the db killer back in. The tone is deeper with a stronger "growl". This set - up, pure and simple, makes the bike sound amazing :shock: .
Not sure how much lighter this system is than the previous set up (stock y-pipe with GT-RX slip on), I'm guessing another couple of pounds shaved. I'm sure Todd can provide the exact weights for the different set ups. But compared to the stock monstrosity, the weight savings are huge.
Before Todd shipped it to me, he made a jig for production. When that "officially" begins, I HIGHLY recommend this system!
Thanks again Todd!!!!!

My pleasure Kevin, thanks again for stepping up and your patience in getting it to you. I should be able to have a few of these for immediate sale/delivery here in the next few weeks.

Bike looks awesome Kevin. I'm jealous.
 
Re: New Griso GT-Rx™ Exhaust Offering

Thanks Davis!
Got some extended riding time in yesterday and as an unexpected bonus, I am convinced the bike is running even better with this exhaust system! And it was running great before.
I am a very happy Griso owner right now :D
 
Re: New Griso GT-Rx™ Exhaust Offering

I have the s/s gtrx right side exhaust, and wonder if this stubby would be compatible with my rightside y-pipe. Wonder if the sound will have more grunt ? Will it be offered in full s/s , instead of s/s-carbon ? Any reasons why not ? rguzz.

I missed this until now. The stubby muffler is not compatible with the right side, no. I hope to get some dyno numbers on all of the systems this year. Are you asking if I'll make my S/S GT-Rx meg in this fashion? Your question is unclear.
 
Re: New Griso GT-Rx™ Exhaust Offering

The stubby muffler is shown in Stainless Steel with Carbon fiber ends, as well as a full carbon version. I think he was asking if there is a Stainless Steel only version.
I would think you could make an adapter (in essence an elbow) to adapt the stubby to the right side pipe. I don't see a lot of demand for that so I am not sure it would be worth it, but I don't think it would take much to make it work.

The metal version is titanium. It's only offered in Ti or carbon. I would have to have the connector and meg/muffler back, as each one is hand made in order to make a connector from the Y-pipe to the right side. Additionally, it would likely need a new bracket/hanger. At this point, I don't have the time in the schedule to take on such a project, but perhaps later this year if he's really interested.
 
Re: New Griso GT-Rx™ Exhaust Offering

Yes would be interested in right side Stubby Exhaust made in s/s or ti, to clamp on to my existing gtrx r/s Y pipe, which in turn is clamped on to standard headers. Would like removable db killer, to adjust for good volume. Please let me know.
