GPR Exhaust

[Joe Mana]

Sounds like I am going a hell of a lot faster

I'll second that Dan.

It sounds like you have a nice group of riders out there in Jersey. I'm a Jersey/Philly boy myself, transplanted to the West Coast. Ride safely!

I put both baffles in at install. Rode 80 miles today. I love the sound. It is very low and mellow until you grab the throttle hard, then it roars like a beast.. I'm afraid to take either baffle out for fear of loving it even more. Seriously it is is perfect for cruising with no droning, and perfect for blasting through the city.

jcolbyc - So you got the pipe for $439 with both baffles, who did you get it from? I want one!

[jcolbyc]

Yep I bought it from motochepassionesrl on ebay. I bought the Titanium version of the one pictured above on Joe Mana's post. It does have a carbon fiber end cap that look really great and is probably a little lighter than stainless. I mainly bought the Ti one because that is what I had installed on the Scarabeo before I got the Mana. When I purchased I also bought one for my wife's Honda Sh150i. so I just sent them a message in ebay and asked if they could throw int he baffles and they said sure.

Hi guys,

Im thinking of replacing the stock exhaust - I have never done it myself before and am not too technically minded but can do the basics. is it something that can be done fairly simply or should I take it to the shop to fit?

thanks for any info

If memory serves, it is just 5 or so bolts and the O2 sensor to remove the old stuff and three bolts and O2 sensor to install the new. Very easy. I could have done it much faster, but just took my time.

Good luck.

Unplug the sensor's electrical connector first. Then it takes only an hour or so to install the GPR.

Do you know if the exhaust is the "permanent type" or if it needs repacking from time to time?

It eliminates the cat right?

[jcolbyc]

It eliminates the cat.

So I just got a stainless steel GPR, it looks just like kame's the OP. Surprising how heavy the stock unit is, a 10 to11lb. savings, and the titanium version saves another pound. Install pretty easy, I took the header pipe off the front cylinder to make it easier. Directions said to take the gaskets out of the stock unit and install in the GPR, but they didn't seem to fit so I left them out. The bike runs great, no signs of any air leaks.

I took it out for a test ride with both DB killers and I like it. I was concerned it would be too loud, but at cruising speeds, in touring mode, below 60mph you barely hear it, but it rumbles when you accelerate. On the highway at 80mph you can hear it, but it's not bothersome. I guess you pick up about 4hp, and the bike seems a bit more lively, or maybe it just sounds like it is.

OK, maybe I am an idiot but, I laid on the ground next to the Mana, trying to figure out how to remove the stock exhaust. From what I can see there are two pipes going into the exhaust can. It seems to me that you'd have to remove the whole thing at the cylinders. What part does come off exactly? And where is the lambda sensor? I searched and did not see anything even resembling a sensor. I am sre I am not looking in the right location. Thanks for the help.

As stated, there are 5 bolts. The ''exhaust can'' under the bike is the catalytic converter. If you follow the front pipe you'll see that it has a clamp under the motor, a few inches in front of the converter, that needs to be loosened up. The rear pipe has one too, it's in front of the swing arm and can be accessed from just below the swing arm on the left side. The converter has 2 bolts, one on each side below the footpegs, that are unthreaded on the ends, and fit into rubber supports on the converter. The 5th bolt is the one supporting the exhaust pipe. I took off the front header pipe as well, it made it easier. The O2 sensor is on the right side of the converter, the wire runs to a connector near the front sprocket, unplug this first. When you get the stock pipe assembly off, unscrew the sensor and screw it onto the new pipe.

Hallo i am new here in this forum and i am from Greece. I want your help because i order from ebay the same exhaust like yours(titanium with carbon end) with 439 dollars + 20 dollars for shipping (a very good price i think). I stay in a town here in Greece and i want to ask you if i will have a problem without the 2 DB killers how loud it will be without them? Also i want to ask you if it will be easy to installed it alone or is it better to go to someone specialist?

Thanks a lot

e.g. My english it's not very good sorry

Hi, I've just read all this post and thought I'd have a look for the pipe on eBay uk, and found this warning

QUOTE: 'THIS IS A ROAD LEGAL EXHAUST FITTED WITH A REMOVABLE DB RESTRICTOR AND REMOVABLE BAFFLE. PLEASE BE CAREFUL WHEN BUYING GPR ON EBAY. IF THE LISTING SAYS "FULL POWER" IT MEANS IT IS NOT UK ROAD LEGAL AND WILL BE STAMPED NOT ROAD USE AND WILL NOT HAVE A REMOVABLE BAFFLE OR DB RESTRICTOR. THEY MAY ALSO HAVE A DIFFERENT INTERNAL DESIGN. THESE VERSIONS ARE CHEAPER BUT IN MANY CASES THEY WILL CAUSE POOR RUNNING AT LOW REVS. IF NOT SURE PLEASE CALL US FOR ADVICE. UN-QUOTE

This only caught my eye because a few of you have said you didn't get baffles or DB killers supplied when you purchased your pipe.
