I would appreciate any experiances people have had with Arrow and Marving exhaust systems, make and model of bike doesn't really matter since I'm mostly interested in the quality, fit and cost.

Thanks in advance.

Bump bump

Hello, I realise this is a thread resurrection but I wanted to post my thoughts on the Marving (AMACAL) exhaust. I couldn't find much when I searched.

My bike is a 1999 Yamaha XT600. I needed to replace an old Leo Vince X3 that was too loud for me, and past its best.

I considered the Arrow and the Marving. There seems to be more people who have the Arrow but the 'not for road use' element put me off. Also many reviewers state that it is quite loud.

Purchase
I ordered the exhaust from wemoto.com on Monday and it arrived on Tuesday. The cost was £175 or so and delivery was free on UK mainland.

In the box
In the box was the exhaust all nicely bubble wrapped and a Marving logo plate that you can stick on if you want. There is a clamp for securing the exhaust to the downpipes. There are no fitting instructions - not that any are really necessary. I was really pleased with the quality of construction. Nice welds, nice chrome and an aluminium plate for the visible part of the can. Better than I expected. There are no bolts in the box so I had to head to a well known hardware shop to pick up a couple of M10 bolts and an M8 bolt, plus washers.

Fitting
The Marving is a single piece whereas the Leo Vince that it was replacing was 2 piece. This made maneuvering the exhaust onto the downpipes a bit more fiddly, but not a problem. I had the Yamaha graphite gasket, but the inner diameter of the Marving pipe didn't seem designed for it. I just used some exhaust paste.

The Marving has a captive nut for attaching the pipe to the frame of the bike just behind where it attaches to the downpipe. It has 2 mounts for attaching to the frame at the can. These allow for horizontal adjustment but not vertical. After a couple of trial fits it was clear to me that these mounts would not quite fit the frame on my bike, so I had to file each one out to allow for a little vertical adjustment, only by a couple of mm. After that it fitted well.

Sound
Thankfully the bike is now quieter than it was with the Leo Vince (I never had the sound deadening thing for it). I can't compare it directly with the stock exhaust because the bike had the LV on when I bought it. However I also own a TT250 with a stock exhaust, and the Marving has a more heavier tone that this and a bit louder.
On hard acceleration you still get a good roar, on shutting the throttle I still get some audible burble (and the odd pop, my bike may be running a bit lean). On coasting and constant throttle the noise is not intrusive.

Performance
I can't tell a difference. However now that it doesn't deafen me and all around, I am more prepared to give it the full beans. So in that respect the bike is a lot faster


One other thing I noticed is the frame on the rear of the bike now 'seems' a bit stiffer. It must be due to the new exhaust being a single piece. The evidence is totally empirical: I have a top box on my bike with a chain in it. I used to hear the chain bouncing around all of the time, now not so much.

It is a bit smaller than the LV in length and diameter (it is round, not oval). You can see more of the rear wheel from the side now, which is better aesthetically.

All in all its a significant cost for the value of the bike but has been worth it for me, as I'll use the bike more.

Cheers

I'm doing a complete overhaul/rebuild on my '86 XT600 Tenere. Having looked at all sorts of alternatives I think I'm going to go for the black chrome Marving. I want a big single sound without being so loud as to make the traffic cops ***** up their ears as I ride by. The black Marving I think will look best for the gutsy no nonsense look I'm trying to achieve. Anyone got any opinions on this ?
Thanks

I've had a Marving from Wemoto on my bike now for about 2 months. I'm fixing to do a trip across the states with it and have done other mods to the bike, one of them being a K&N filter in the airbox, so I can clean it on the road and continue without having to find or carry more air filters. The thing is, the bike runs almost the same as standard, and all the carb settings are standard, but I get a pop sometimes when I'm decelerating from speed or a small pop as I change gears, ie at the second of change when I snap the throttle off before engaging the next gear. I think it needs a little bit bigger pilot jet to rectify the situation. Has anyone else had any experience with this?

I get the odd pop as well but the bike runs so much better with the Marving as opposed to the stock exhaust on my 1998 XT600 so I wont be faffing about with jets.

I have an Arrow on my TT600 which is far too loud, even with the baffle thing attached. I prefer the Marving. I had to fiddle about with files to make it fit but I'm happy with it.

Reviving an old thread again but does the MARVING silencer save a bit of weight on the stock exhaust?

I heard people saying changing the stock exhaust for an arrow saves a bit of weight for example.

Just bumping this question (bike is xt600e)

I fit the arrow.
Went on super easy!
Louder but not Too loud.
A lot light lighter than the stock one.
Excellent build quality.
Happy to recommend

Not sure if anyone cares after literally 10 years... but I just received the Marving AMACAL and weighed it at 3.5KG.
I also still have the original, weighed at 5.1KG.

That said, my original exhaust is quite crusty with some holes in it. I wouldn't be surprised if it is 5.5KG originally.

I think the Arrow should be around 3KG, if I'm not mistaken.
