My LeoVince slip-on has been shipped and I should get it next Wednesday. That's 3 weeks sooner than promised.

Here's the info sheet on it:

I'll be doing a youtube video on the before and after sound. I'll also add a K&N to complement the lower exhaust restriction.

Anxious to see and hear.

BigBird,
Any chance there is a dynotune (the makers of Power Commander) test center near you. A dyno comparison before and after would really quantify the results.

Dan

I did that for the full LV system, and the malossi variator, and the PC.

Bigbird, where did you order the LV from?
does it use the OEM pipes and headers?

OK, LeoVince 8552 slip-on installed, tested, and I'm very happy. I've posted some pics in my album, and in the next couple of days I'll complete the youtube video and post the link for it here.

Impressions:

1) It's LIGHT, way lighter than the stock muffler.
2) It is not overly loud, in fact at steady throttle openings at highway speed I can't tell the difference between it and the stocker. There is absolutely no highway droning.
3) Under heavy throttle application, it has a nice bit of bark to it. Nothing like an HD V-Twin with shotguns, thank goodness, but a bit of a bark nonetheless. It makes the engine sound more like an internal combustion engine, not a sewing machine.
4) On throttle let off, as when rolling to a stop, the stock muffler used to "pop" due to leanness as air was injected into the exhaust port from the PAIR valve. The LeoVince emits something between a "cackle" and "burble".
5) I'm extremely pleased with this mod. I have nothing negative to say about it. Construction of the muffler and parts is first rate, with excellent machining and welding of the stainless steel.

More to follow.

Thanks for the report. I am interested in this mod for mine (2009).
Did it come drilled and tapped for O2 sensor for US model 600's?

Thanks
Bob

Thanks!

In addition, I can't wait to hear if there was a performance increase. Tell us you weights and did you install a different cluth yet?

Thanks
Bob

Here's the URL for my youtube video of the new muffler:

Sweet! Does the angle of the can follow the body better than the previous one?

Yep, looks like it still tips up, but not as bad as the previous.
Btw the Yosh rep called me, wondering why i didn't show up at Hallet last weekend. said when he was at HQ, they had a silverwing on the test bed doing R&D!

The Yoshi buzz. Very familiar!

Excellent report Terry. LeoVince should use it for marketing.

Awesome video and commentary, Terry.
No questions left unanswered.
I agree with "Hi Yo".

Thanks, guys.
I suppose it's the teacher in me that makes me want to share. If someone asks, I try to help.

Thanks for the video. A nice tone without being loud. When I put the LV slips ons on my VFR, I too left in the db killer. I immediately notice the bike seemed to rev more freely and the weight loss made it more "flickable" in the twisties.
Do you notice those affects or is it too early to tell? Not that I consider my SW "flickable" but I am a nut for weight reduction.

Thanks
Bob

One more thought. After riding tonight around town in 26C stop and go traffic for 25 km the thing I noticed most was how much cooler the LV runs than the stock muffler. After pulling in to my driveway, with the radiator fan going on and off intermittently, I could almost touch the muffler. Try that on a stock Swing muffler after a ride. Of course the reason is that there is no cat converter inside the LV.
My saddlebags were much happier with no oven cooking below them on the right side.
That alone is worth the muffler change for me.
On the other hand, my wife was not too pleased. She likes the quiet stock muffler much better. She said the LV was too loud. Maybe because she's sitting further back she gets more noise. To me, it's not loud at all. The Yoshimura exhaust on my SH150i was way worse. It barked and droned annoyingly. I told her next time to wear earplugs. She wasn't too impressed with that.

After all the posts on here about noisy pipes, and you had a noisy Yoshimura exhaust on a 150cc 15bhp commuter scooter?

You should encourage Mrs bigbird to wear earplugs when on the scooter with you, it's part of ALGATT.

Here's the followup video of the new muffler with the dB killer removed.
Those who don't like performance bits need not apply

Performance difference?
