Any love for Delkevic slip on exhaust?

[Ant]

They seem to have a good reputation and very reasonably priced ($1100 for an Akrapovic? No Thanks)

I see on the website there's varies sizes, 8" to 18", can I guess that the smaller the length the louder it is?

Thoughts?

Delkevic make great quality products, and try to tend to use 1 piece where they can for headers and link pipes to avoid having a dozen springs holding a dozen pieces together, though their styling is a bit dated. They look amazing on a 90s fireblade, on a modern bike like the XR? not so much. Their only "modern" ish looking offering at the moment is their titanium silencer, which is priced so you might as well go with another brand like arrow or scorpion.

As for sound, having spoken to both delkevic and black widow, the shorter it is the louder it is, about they recommended around 350mm for street, anything above for tracks with noise limits, below is just asking for ear bleed.
Carbon also makes noise bassier and less high pitched therefore less painful to the ears. triangle and hexagon designs further make the sound slightly deeper and bassier. I've had my eyes on a 350mm carbon trioval from black widow or their 300mm carbon hexagon, but I'm worried that'll be too loud. I have no personal baseline so I can't tell.

The titanium Delkevic over $300 cheaper than the Arrow, that and all the positive reviews is what gave me that tingly gizzard feeling that one gets when browsing motorcycle accessories.

Oh wow they dropped the price, last I checked it was close to 400 quid and arrows could be had for 450. That is indeed a very good deal. I do recommend you check out Black widow aswell though. Delkevic is definitely up there in quality with the big boys, I know at least half a dozen people who have delkevics and not a single bad comment. Black widow had a few bad eggs years ago but their quality is close to the same  as Delkevic now and I think they have some nicer endcan options.

I'll give Black Widow a peek thanks.

About time there's affordable and quality slip ons

Got the B/W 350 tri on mine, with std headers, noise isn't much different to stock with baffle out. looks decent when B/W sticker removed (wasn't even on square) but not overly impressed with quality of fitment. Personally I wouldn't buy B/W again. Rather spend more on an Arrow or similar.

I had a full black widow system in my ER6 it needed a bit of wiggling but once in place no issues at all. The sticker on the 300mm tri oval did peel on mine too but they started using metallic logo plaques a while back which are said to hold up much better

My can was new couple years ago and had the sticker. like I said, wasn't even on square so not great quality control. If you want half decent looking but cheap they're ok, but if you want good quality go for something better

By a while back I meant last 2 years or so. I got mine on my ER6 about 4 years ago and much the same story. The fitment is largely down to how all pieces are slid together and springs holding them instead of being a 1 piece, it's the same story on the XR's black widow headers, but those there was absolutely 0 fitment issues.

Here is how it looked brand new VS after about 2 years. Most of the peeling happened when i accidentally went over the exhaust with a jet wash real close. (Excuse the dirty bike)

How does titanium fit in the sound spectrum?

I'm confused at their descriptions as to what they mean about 'stuby'.

I have my list narrowed down to just 5
