I don't like the M4 system due to the muffler/silencer. Anyone know anything about Dominator? GSX-S 1000 / F 2015 - 2020 Low Level Full Exhaust System HP8 BLACK DOMINATOR 5906726949393 | eBay Their site says 5 year warranty and made in Poland. It sure would be nice to find something not made in China too. I may be going with this system. Appears I could possibly fit a Lextek slip on if I don't like theirs.

Don't know anything about how it performs but it looks like it has a real silencer on it compared to the M4. Looks like it has longer secondaries than stock so that is a plus. I am familiar with the company. They sold a bunch of cat delete pipes for our bikes and those who bought it said quality was good.

I'll probably order one when I get back from vacay the week after next. Kind of tired of waiting for the "others". I know Karns Performance installs a Delkevic header and Lextek slip on with his own fabbed connection pipe to keep it a low mount, but I'm 6 plus hours from him and don't see that happening.

Pretty impressed with these guys. They have responded to me quickly and their plant is quite impressive.

Two negatives after talking to them and watching they dyno review. Only their muffler/silencer works with this system. They dyno was done with the much louder slash cut style system, not the HP8 muffler/silencer. I do believe I will keep waiting for Lextek or another brand to release a low mount that can use multiple slip ons.

Not much incentive to develop something for competitor to use their product with imo

Yea but Arrow, Delkevic, Black Widow, Lextek all sell their headers separately. If you buy one that doesn’t, you’re stuck with that sound and look. I want some flexibility.

I mean there's always a Sawzall...

Yea, I just want the necessary hardware and bracket to install it properly. Lextek has made a system as their guy Paul has it on his bike. He’s on the FB page. For some reason, they are dragging along with releasing it. I would say there is a supply issue as many of their slip ons are not available.

I found another one from Brazil called Jeskap that looks very promising. They are also in Portugal. I stumbled on it by searching youtube. A guy was showing it off on his new 22-23 GSX-S1000 naked. I've emailed them asking for details and if they can ship to the US and pricing.
Worst case scenario, if this Dominator system has a worthwhile header design (I'm far from an expert judge on these), I have a friend who does high performance custom ATV work and I could have him cut the muffler off if I need to replace it.

You can do what I did originally and install a Lextek header. Any slip-on that will work with the factory exhaust will work with the Lextek header, so it gives you nearly unlimited options as far as trying different slip-ons. I've gone through five or six different ones and finally settled on an Arrow header with an Akrapovic titanium slip-on. I did have to modify the Akra in order to fit it to the Arrow header, but that wasn't an issue with the Lextek. And there was nothing wrong with the Lextek header. It performed great for the price, I just preferred the Arrow. That said, the Lextek is a very close copy of the Arrow. I posted pics here somewhere of both headers off the bike and it's quite obvious that Lextek based their design off the Arrow design.

This is what I ended up settling on (Arrow header/Akra slip-on). I believe it sits low enough to allow room for your bags.

Thanks! Hindle has a nice system that I like the looks and sound of, but it’s a bit pricey and no dyno numbers that I have seen.
