Leo Vince or BOS, 2019 XT

Hi everyone,

It's time to give Athena (my XT) some more bark. Anyone have experience with either the Leo Vince Nero or the BOS Desert Fox slip-on for a 17-19 model? My choices are limited here in Germany, to avoid potential expenses, headaches and penalties it has to be an option from the short list of TÜV-approved parts, these two are both good quality parts that qualify.

I have Leo Vince EVO's on my RC51 and they sound great & work well with the otherwise stock machine, and the Nero is also listed as specifically designed to work with an otherwise stock system.

One question about the Leo is, how loud is it with the dB killer removed? The EVOs on my RC are literally painfully loud when the dB killers are out, I like a bellowing exhaust as much as anyone but these are truly excessive.

BOS is a big name in exhausts in Germany, also known for building well-designed systems that work with stock machines, and their info sheet also states that their exhaust offers a small measurable performance improvement.

Thanks, everyone.

The problem with Youtube videos is that the true oomph of the exhaust is rarely represented. I tried that back when I was looking for an exhaust for my RC51, and fortunately I didn't go with the one that sounded best on Youtube cuz I've heard it since then in person and I don't like it.

I went with the Leo, I found some feedback on some local forums and I already have a set on the RC that sound great and for the price you can't beat it (looks pretty sharp, too). It arrives this week, I'll install it friday or saturday and report back.

I had originally looked at the Delkevic 3/4 system as it was priced right and the options of how long or short
you wanted the muffler made the loud factor able to be tailored to what the customer wants. With dyno
results videos right on the company website. Many on here complained they were still too loud.

So searching a little more I found the Yoshimura exhaust (Very well known company for many years )
They have an exhaust that is the real deal nice throaty sound not harsh - and a power gain to boot.
Company also offers a dyno results showing at least 5 lb ft of torque gain and 5 h.p and not all at the
top of the rpm band either. More mid range and upper range.

It's expensive around $600 but to me well worth the price on my wish list for next years mod.

2017 DL 650 , Shad 23 side bags, Givi crash bars, 32 watt LED driving lights ,
Goldwing pegs, silver front fender, Lazer cut aluminum Chain guard, Madstad 20" windshield
light smoke tint , Blu/blk Driven Racing Billet bar ends, Stock exhaust for now.
Yoshimura 3/4 system in the oven.
