Yoshimura RS3 Exhaust Can install and review

[Frulk_imp]

I've mentioned before that I picked up the used RS3 off a member more as an aesthetic experiment than the need for a more pronounced sound signature out of an exhaust.

When this one came up for $115 or $125 I decided to jump on it and see how the pipe, the red side covers, the RC2 and brown café seat would look together. A bonus was that that a sound baffle came with the purchase that, if I liked the look but found the can to be too loud, could be inserted to quiet it down some.

I was extremely surprised that I had to search high and low on the internet to get an accurate weight on the can. Near as I can tell the Yoshimura RS3 CARBON can alone weighs between 9.85-10 pounds even.

Once the pipe arrived I went to install it. When you remove the OEM can there is a center stand stop welded to it.

OEM Pipe with welded Tab:



There is a small heavy duty rubber disc cushion on a tab on the center stand that rests against it. This prevents the center stand from going further up and eventually hitting the chain.

Rubber washer bumper (NOTE: once the Yosh bracket is installed this bumper becomes redundant and is no longer in use)



Once I realized I didn't have the center stand stop from Yoshimura I called their Customer Service department and ordered the required parts for $78. Tech on the other end was top notch and very technically astute.

Once the parts arrived I was surprised to see how HEAVY this center stand stop bracket was. I'm guessing the entire thing weighs at or on around 2 pounds +/-. It's nothing if not heavy duty.

Here's the bracket and parts



Here's the bracket and all associated parts correctly oriented and put together for FYI. Imagine sitting on the bike and looking down and that would be how it would be oriented/installed.



Installing this bracket is best done with FOUR HANDS. Without the extra set you're just setting yourself up from some prolonged frustration.

Start by removing the original OEM muffler by loosening the clamp at the front and removing the mounting bolt at the rear. That gives you access to the area you will be installing the bracket in.

Here is the trick to the whole install off the bracket. In the pic above on the right side of the bracket is a thick sliver washer. That washer goes between the bike and the bracket and it's difficult to align it just right if you have to worry about also aligning the other side. That's where the 4 hands come in handy.

After removing the OEM muffler remove this screw from the right hand side. It's NOT reused. You use the screw shown on the bracket on the right side.



Install the bracket. I used heavy grease to hold the washer in place on the right side as my daughter worked the smaller washer in place on the left. I used a rubber mallet to tap the bracket into alignment and then placed the screws and tightened them down.

Slide the extension pipe that comes with the RS3 in place snuggly and tighten down the clamp at the proximal motor end.

Slide the muffler into the hanger and loosely mount it to the bike with the rear bolt. Then put the 2 springs into place.

Snug down the rear bolt to ensure the muffler hanger is tight (don't forget the rubber liner for the hanger).



The RS3 comes with a baffle



Exhaust end without baffle, basically straight through exhaust channel. Notice the screw. There are 2 in place so I have them available should I want to put in the baffle.

My Opinions on the look and sound.

Opinions are like elbows. most people have at least one or two.

The look: It's growing on me. It's a full sized can, not a stubby and somewhat traditionally shaped. It doesn't add to the classic retro look of the bike but offsets it.

The sound: Definitely gives it a low end bass GROWL. Not oppressively loud at all, just more throaty. At 75+ mph it's noticeable and if I was doing an 3-4 day extended weekend ride I'd more than likely insert the baffle.

For sure the motor now lets me know if I'm asking it abruptly to do more work I find myself frequently blipping the throttle somewhat uncontrollably to get that response.

NOTES:

1) Yoshimura customer service is top notch

2) Revzilla no longer stocks the RS3 Carbon. not sure if that means that Yoshimura is eliminating it from their line up.

3) The can is supposed to be repacked at about 7K miles. After watching a video on it I'd rather pay the nominal fee Yoshimura charges for this process as its a mess to do at home. Repacking supposedly brings sound signature down by 2-3 DB's.

4). My seat of the pants dyno can’t tell if there has been any performance improvement.

5) There is absolutely no popping on deceleration whatsoever.

very good rundown. i'm shocked to learn that it weighs that much. the "carbon" must just be for looks. a Similar Delkevic carbon fiber can weighs around 4.5 lbs., and a titanium can from a comparable japanese manufacturer weighs about as much. 9.85 seems just as heavy as a standard steel can.

[Frulk_imp]

Well. That bracket is heavy. So adding that would put the can, pipe extension and hardware somewhere around the 13 pound mark.

Good write up Frulk.

Love the glamour shot.
