Opinions on this exhaust

Better sound, save weight, looks great...and gain a few ponies, what more can you ask for.

How many ponies would have to be determined on a dyno.

The above answer from @Bumblebee is on the money for the question.
I haven’t had their cans, but have had both their 4>2 & 4>1 headers.
Well made, top welds. Great value for money.
I did drop hp/tq going from their 4>2 down to 4>1
Not a huge amount and nothing noticeable on the road.

Would I recommend them? For the price, hell yes.
Is my $2400 full Akro a better system, without question.
But if you’re after weight loss and a cleaner install for not a huge outlay, can’t beat them

The black widow slip ons and link pipe also fit their complete system, logic says that without a tune yes you may loose torque or hp but with a tune and cats removed I doubt that very much

When I had both systems, they had Yoshi cans on them. So BlackWidow 4>2 & 4>1 headers with Yoshi cans.
I had the bike fully dyno’d each time. My graphs and reports are buried here somewhere in the forum. But yes, the 4>2 gave the best hp/tq on the dyno

Ill call Black Widow monday and see how quick i can get cans and link pipes, at a later date Ill prob add the headers, thanks for the input guys

My Yoshimura full exhaust gained hp/tq on my bike (gen 2) and Chris Moore only uses Brock systems and he gains hp/tq with those systems as well...and seeing as they are rebadged Hindle systems, that would mean Hindle gains hp/tq too...

Chris Moore has lots of dyno videos of aftermarket pipes gaining power and no big holes in mid range.

??

MooreMafia uses and recommends other exhausts too.
My friend wanted a full Pentacarbon on his '18 gsxr1000R.
MM told him he could make the same power with a full M4...and it was alot cheaper.
He then flashed and dyno'd it, proving it with 187whp and 88trq.
Good business.

Gotcha, I generally only hear him promote Brock's stuff...

Never been to his shop personally...maybe one day...

Yeah, he does alot of Brocks stuff.
If you do ever head his way, he's 6 hours south of me.
Stop by for a ride!
