• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

G.P.R. Motorcycle exhausts - I'm working for you

So is there a single pipe/muffler on the left side and a open space to put something where the right side pipe was ?? Does it come with removable DB killer or spark arrester. Is there a bung to screw in the lambda sensor ?

make a manifold for single pipe. on this manifold may be mounted either the original exhaust that what they produce. will also produce the pair of silencers you see in the picture. if you buy the pair of discharges and later want to switch to just buy the single exhaust manifold and remove one of the two drains.
produce a storage compartment to mount in place of the discharge of the right.
produce other accessories that in this moment I do not know what they are.
unfortunately today to go for holidays, will reopen in early September. And everything will be ready by mid-September. In mid-September I'm going to get my bike and everything they produced. For the sake of our beloved TR650 I'll be more than a month without a bike, but it will be worth it! for overseas delivery will inform you when I go to pick it up. I think they are resting in an outside vendor

faranno un collettore per tubo singolo. su questo collettore si potrà montare sia lo scarico originale che quello da loro prodotto. produrranno anche la coppia di scarichi che vedete in foto. se comprerete la coppia di scarichi e più avanti vorrete passare allo scarico singolo basterà comprare il collettore e togliere uno dei due scarichi.
produrranno un vano portaoggetti da montare al posto dello scarico di destra.
produrranno altri accessori che in questo momento non so cosa siano.
purtroppo oggi andranno in ferie, riapriranno all'inizio di settembre. E tutto sarà pronto per metà settembre. A metà settembre andrò a riprendermi la moto e tutto quello che hanno prodotto. Per il bene della nostra amata tr650 starò più di un mese senza moto, ma ne sarà valsa la pena!!! per la distribuzione all'estero vi informerò quando andrò a ritirarla. credo che loro si appoggino a un venditore esterno.
 
So, they are going to make a head pipe and a dual exhaust system, a single exhaust as well as a few other products. The head pipe will accommodate their exhaust or the OEM exhaust. They will also be producing a few optional storage containers to be mounted in place of the second exhaust mount if you go with single.

Ciao Mega,
Vorrei ringraziarti per il sacrificio personale rimanendo senza moto per 5-6 settimane. Sono anziozissimo (e immagino altri qua sul Forum) di vedere e comperare il prodotto finale. Ho ordinato Mercoledi' il mio Dynojet power commander 5. Avro' certamente bisogno di un scarico piu' aperto. Addesso incomincio a fare richerca per un filtro d' aria che la fara' respirare un po' di piu'. Non so' se hanno la possibilita' li dalla GPR, ma un serbatoio di plastica tipo Serbatoio Safari sarrebbe un sogno. Un idea tra altre belle idee. A presto Mega e grazio di nuovo.

Ciao Mega,
Thanks again for the personal sacrifice of being without a bike for 5-6 weeks. I am very anxious (as are others on the Forum) to see and buy the final product. I ordered my Dynojet powercomander 5 Wednesday and I will certainly have a need for a more free flowing exhaust. Looking into a more free flowing air filter as well. Not sure if GPR has the resourses, but a plastic (Safari tank type) fuel cell in place of the deleted exhaust would be a dream. Just an idea among ideas. Talk to you soon and thanks again.

Any updates yet? Many of us would love to hear a sound clip of it starting, idleing, and reving!

Semi local to you Bills (BMP) in salem Oregon posted one and might have them for sale, not sure. Looked and sounded great.
 
Would love to hear it...know the potential weight savings if any (with 1 can) and what a PC might add to the overall TR experience.

I've spent way too much on fake promises in my years...but I'd be all over it if a couple of you guys go first and give a thumbs up. I wear ear plugs but my neighbors don't so I don't want it too bothersome. I'm not on the HD bandwangon or it'd be ok to be loud and block the road...but then I'd have to wear that pirate outfit and that's where I draw the line!
 
sorry for my absence but I was (still am) on vacation and I have not contacted anyone to date. So I am waiting for their response, but I think now it is really a week at most two. As soon as I 'definitive news I'll tell you right away. Thanks hello to all

scusate la mia assenza ma ero (sono ancora) in ferie e non ho più contattato nessuno fino ad oggi. Sto quindi aspettando una loro risposta ma credo che ormai si tratti veramente di una settimana al massimo due. Appena avro' notizie definitive ve lo dirò subito. Grazie ciao a tutti
 
Is GPR actually tuning this pipe and muffler system or just making some thing for aesthetics? I would be interested in a tuned pipe but personally if it is just a remade pipe fit a slip on muffler I do not see the point in changing. Would be cheaper to make your own single pipe and slip on any muffler. Although if it is tuned to correct length and back pressure would definitely be interested in a single and add a storage on the left for rain gear, gloves etc. Then I would not have to have a rear luggage box or back pack. Also with the pcv and auto tune I will be getting it would help. I read the different reviews and if the exhaust was tuned right do you think it would be at 100% duty cycle. Also could you change the injector to a bigger one?
 
Tuned would be certainly good and I imagine given their presence in the exhaust industry, that that would be the case. Having said that, I would personally still buy if not tuned just to shed the weight of the stock cans if nothing else.
 
Any pipe that divides into two with one bit shorter than the other is going to be "tuned"... er.....interestingly. Harmonics don't work that way. The return pulses from one side will be different from the other AND there will be a return from the junction of the two pipes because they suddenly get larger in cross-section then narrow again which would produce another reflection. Not impossible, but seriously problematic.
Any single pipe ( within reason) to the muffler, with proper mufflers, will be tuned better than the divided pipe ( The std mufflers are not proper mufflers . They are cats and chokes)
 
I have my Strada running good right now. Running a BP..stock otherwise. I have looked at the PC and may go that route ....IF a decent exhaust becomes available ...(fingers crossed)

I have a old supertrap that I thought about trying to fab something up for...it's a pretty big..(heavy) muffler that I actually used on a rotary engine car..way back when...on a 1980 Mazda RX7. I think it'd be too big & heavy.
 
When they make the single can available I promise to myself to get one, along with a PCV, and have the whole shebang dyno tuned to make sure all is good! Love the black can!
 
It is pretty damn sexy right!? I just hope there is a US distributor... Shipping direct from them was CRAZY $$$$$$
 
CIao Mega,
Ben tornato. Spero che hai fatto buone ferie. Siamo anziosi di sapere il progresso dello scarico. A presto!


Hello Mega,
Welcome back. Hope you had a good holiday. We are anxious to here progress on exhaust. Talk to you soon!
