OK, I have read a lot on here in the short time I have owned my bike and the biggest thing I read was how big the stock pipe was. I agree, it is huge and in my opinion ugly. That is why I had to change it out and I went with the Yoshi R-77 carbon pipe and man am I glad I did. This bike sounds like a whole new machine and I love it. I was like a lot of people, I live in a neighborhood that would frown on a very loud bike especially since I leave to work early in the morning. This pipe has a great low rumble at about 3-4 grand so I just shift a lot to get out of the neighborhood then I open it up and just listen as I drive the rest of the way in.
The total change out time is about 30 minutes. It is very easy, 3 bolts to take the old one off and 2 bolts and one small hole to drill in the existing header to put the new one on. The sound and the look was way worth the money. I purchased mine off EBAY and had it in 4 days for a total cost of about $450.
If you are on the fence as to which one to get this is a great choice, also it does come with the DB killer if you decide it is too loud.

Nice!!

I agree. I also have the same pipe and I love the sound and it looks so much better without the bazooka.

Just thought of sharing a picture of my bike.

The TRC Carbon Fiber slip-on looks and sounds pretty nice as well...

I agree with you on it being worth the money. Here I have the two brothers system.

Nice exhaust guys !!! Did you find the need of having to drill a hole for the securing rivet? Also was disabling PAIR system necessary?i.e. if you get popping noise on deceleration? Thanks !

I have a Yoshi TRC CF pipe on my black 2008. Love it !! I drilled the small hole in the standard pipe when installing it, no big deal at all. You could probably get away without doing it, but I figured it was not going to cause any issues to do it and added about 10 seconds to the installation.

I haven't disabled the PAIR system... I do get some popping on deceleration. I might get around to it one day, not high on my list at the minute, I want to finish off a few other things on it first.

I installed the R-77 carbon slip on and am very pleased. I have noticed a definate improvement in the throttle response. Yes it will pop on hard deceleration without the db killer in. Any exhaust system will if you open it up. Don't try to fix it. I am a tech at a suzuki dealership. What you are doing in adding on this pipe is increaseing the volumetric efficiency of the engine to some degree. The PAIR SYSTEM acts simillar to the EGR valve on o car but it adds fresh air into the exhaust to reduce emmisions of NOX. The reed valve allows air into the cylinder head directly behind the exhaust valve. It doesn't lean out the air fuel mixture but it will have the added benefit of cooling your exhaust temperature and prolong valve life. My advise is DON'T DISSABLE IT! It is there for a very good reason. Eliminating it wont cure the exhaust noise on deceleration. If you dont like the noise put in the db killer or don't put the pip[e on.

Thanks so much for the info, never thought about it as enhanced cooling. My only concern is, the constant popping is going to damage to the packaging inside the exhaust (since it is excessive fuel burning in the exhaust) and I would likely to reduce the frequency of repacking if possible. A lot of people of disabled PAIR system or remove it on the forum which completely fixed the popping noise. Appreciate your advise

The R77 design has been borrowed by BMW they too had alarge ash can on one of the new fours, but after a year
designed one very close to the volume idea of YOSH. I too running the R77 with insert.

Hi hctseng i have some questions that i hope you can answere. You mentiion the PAR valves i agree with you
about leaving in place what i did not know it helps with exhaust valve cooling, does the "PARS" also help
in lowering the piston down stroke pumping pressure with the PVC valve?

And i and a few others have added the Bandet 1250 oil cooler, do you think Suzuki should have put on ?

The PCV cover is a vented cap on top of the engine directly under the throttle bodys. The PAIR consists of a ECU. controled solenoid and a reed valve that opens a port inside the haed the allows fresh air into the exhaust system directly behind the exhaust valve. The PAIR system function completely independent of the PCV

Thanks for your expert advise, do you know if the popping would cause damage in the packaging inside the exhaust i.e. Yoshi R77? I would like to reduce the frequency of having to repack if possible since it can be quite a pain. Thank in advance

cool
