Modern Vespa

Requesting your opinions as to the lowest-tone aftermarket exhaust system out there? Would just like to get a little deeper sound...

Thanks

Easier to get in the US and not a zillion dollars: Leo Vince 4 road.

More of a PITA to get here,but doable, I got one: PM tuning pipe.

Ah, thank you, Maestro! Where can one get the PITA PM tuner? What kind of frogskins we talkin' here? $400? Do it sound deep?

The PM was more like $800+ with the "awesome" exchange rate and shipping. PM will not sell directly to the USA, so you have to find it from a european supplier like SIP. Either of the two pipes I listed are much more "throaty" than the stock aomeba-wineskin-space bladder.
The PM is louder than the LeoV. I would describe the PM as "deeper" and the LeoV as having more growl.
Earplugs and a FF helmet = deep sounding exhaust.
Even the seat latch sounds tougher...

removal of the baffle on the LV and it's quite loud, comparable to a dirt bike

800 skins.

Well. B'lieve I'll give Leo a shot.
and a bafflectomy, you say; maybe a partial bafflectomy...

Thanks again

Why, just got to hear the LV4road over on YouTube - by gum, that did sound nice when that fella throttled-on...yassss....

Ask Jess about the sound of a "partial bafflectomy." His seemed to perform such on itself slowly across many miles, and got louder and louder... but in a cool way. More throaty, for sure.

No pipe on the market is loader than the LV sans baffle

Other than mine when the down pipe cracked in 2



Plus it did that in France , only 10 miles from the ferry though, so made it on and and off and called the AA in Dover.

noisiest debarkation since 1066, I reckon...

Ouch. Yeah, I rode quite some miles with a busted exhaust stud and then a busted downtube. SO loud. Christ, that was really loud and annoying at stoplights... backfiring like crazy, also.
True about the LV being the loudest without the baffles. It also doesnt sound as cool that way though, IMHO. LV should have the baffles in, and then it has less of a leaf blower sound to it. Ask Glasseye about the sound of his Chucky bike. That thing has/had an LV on it and it sounded SUPER burly, and most of the sound was from the air intake modifications.

air intake mod!? is there a k&n that'll work? a scoop, perhaps!?

where's dat 'soich' button...

EDIT: got it......yasss...

Try getting on and off a ferry with a load of Ewan & Charley wannabes looking at you on their BMWs

The Prima is way throaty.

I've never heard an LV with the baffles out, but for $269 (if the special is still on) it's a smokin' deal for anyone who likes a deep loud pipe.

It's so deep it pulsate's the tarmac you are parked on, it must be something to do with the size of the muffler chamber, you feel it through your feet within a 4ft radius of the scooter when it's idling on the center stand.

My 4 year old daughter burst into tears the other morning because she thought daddy had left without kissing her goodbye, I hadn't, it was the Harley from up the road went past.... (true)

edit: it's on special.

Huhhh...ground rumbling, you say; like distant artillery fire...hmm...YouTube search time...Prima...

Well, the most relevant I found has a guy on a Buddy 125 - a pink Buddy 125 -ripping up and down between storage spaces faced with metal doors that increase the reasonance...damned loud and deep...

Yeah, like that, but the GTS sounds like that without the need for the echo-ing roll-a-doors (twice the c.c's I guess) and the GTS revs way higher (mine does with the J.Costa anyways).

It also has a burbling back-off note that's just killer

It's true. The engine on my '08 GTS seems to run hotter than any of the other bikes on Cannonball, as evidenced by the intense browning of my whole LV pipe. That, coupled with Cannonball miles being somewhat akin to dog years, and my baffle broke somewhere between day 5 and day 6 (not sure exactly) and continued to rattle around inside the pipe for the remainder of the race. I haven't yet taken the time to attempt to weld it back together, and am using the stock exhaust for now.

I miss the LV pipe, though...

"...Cannonball miles being somewhat akin to dog years..."

Hah! Well-said you; love ride-it-hard-til-it-blows trips, febrile with coffee and wind burn...

PM, everything else is for girls

How does one fiddle with the 4Road baffles? is it just a simple as removing those two hex screws at the ass end and removing the plate? ???

My LV pipe is slowly getting louder as time goes on. I wasn't really expecting it to do that since the contents are ceramic I think?

Then theres the issue of the PM Pipe clearance....
and the stiff-ass springs.....Maver? or is it suit scoot who has the SP4U springs?

Interesting comment from someone whos into teabags. Tea Time yet?

I will have a PM on my new GTS soon.
I will letcha know if there are any clearance issues... I like the fact that the header length is actually tuned properly. The LeoV just used the stock downtube, and that seems to love to break. I will be glad to get that off of my scoot, and keep it somewhere for if (when) I break the PM somehow...

it should be here tomorrow. I am glad about it.

...when you install it incorrectly.

The packing wears out, it's essentially fiberglass insulation. They need replenishment from time to time. From Leo Vince's own website:
The products of the SBK range are internally fitted with highly thermally and mechanically resistant fibreglass
wool, but due to the very nature and function of the silencer itself, they are liable to wear.
As described in paragraph 3.00 of the General Guarantee conditions in the booklet accompanying every LeoVince
article, regular maintenance must be undertaken on the product.
On those bikes of standard configuration in terms of engine and carburetion, it is necessary to undertake checks on
the state of the actual sound deadening material according to the frequency indicated in the respective user and
maintenance manuals of the other exhaust system components. The average duration of a silencer obviously varies
according to the load applied and the conditions of the roads run.
Should the deadening material be found to have deteriorated, it should be replaced before this deterioration
actually affects its heat insulation potential towards the exterior of the silencer, which will in time risk damaging
the carbon mounting brackets and /or the original plastic protections.
NOTE: the replacement of the deadening material must be undertaken exclusively using original LeoVince spare
parts and following the assembly instructions as provided in the pack.

I removed my LV just to replace my tire, and a not small quantity of fine white dust poured out the inlet end....spent insulation. When they get louder and louder, it's as that wool packing deteriorates. They speak of the SBK Range here, but it's the same for pretty much all of them....

+1 for Leo Vince! has a nice deep growl that makes people turn and look at you. Love it.

Theoretically yes, but you may have some difficulty with it. Did you have an aftermarket exhaust on it?

How much does this cost to replace (sans warranty)?

Wow, lots of info on it, thanks Mattgordon!

But I did the install with YOU!!!

Aren't the new LeoV's one piece from the downtube back?
Mine was a 2 piece type situation, and it took a beating and still kept up the goodness.
