Looks exactly like the Hp plus slip ons from khromewerks in my pic above. Dog balls, Huh? Nice.
Interesting because Khromewerks has had a patent on that baffle for a long time.

From their website. The dog balls baffle as they call it says patented too.


Here's the HP Plus again. Took that just before I installed them.

As far as dyno numbers, I can't speak for their 2in1 but the Khromewerks slip ons have great low and midrange torque. Sound good too. Nice deep rumble.

They do make this. 2in1 Torque Booster Conversion Kit

The exhaust that do better up top have a broader torque curve with less midrange torque. Mine has a steeper curve with great midrange. I've contemplated experimenting with cutting some dog balls off to broaden the torque curve just a little.
I see none of the exhausts with the broader torque even hit 80ft.lbs., more like mid to upper 70s wiith similar builds, where mine peaks at 88ft.lbs. around 4500rpm gradually dropping to 68 at 6500rpm.
Ideally I'd like to broaden it a bit more up top but still peak in the low to mid 80s. I don't want to lose the great midrange.
So if I were to cut a dog ball or 2 off, which dog balls would be best to cut? I know it's always been keep the balls closest to the end of the pipe.
Or maybe cut half a dog ball off at one end or the other or both making for a bigger opening/exit?

Since you're dealing with dyno numbers you've "adjusted" to what you think they "should be" why not just make up new numbers?

Your jealousy creeps it's ugly head once again most likely because you never 70ft.lbs. with your girly cams and lost compression. Explains why you never produce one yet make wild, unsubstantiated claims of no loss of low end with great power up to 7000rpm which we all no is total bs. Put up or stfd. Motorcycle mechanic my ass. Tire and lube tech maybe.
You can clearly see my first dino when the printer worked was 87ftlbs. Excuse me, 86.8. So if you think another ft.lb or 2 is b.s. after fixing a breather issue that had my head gaskets weeping oil on the dino, rejetting, and timing is bs sobeit. You're the last person i have anything to prove to. I challenged you to a pull off on the dino. I knew you wouldn't show. You'd be chomping at the bit to prove your bs claims if they were true. My offer still stands son.

You can clearly see my first dino when the printer worked was 87ftlbs.
Actually I have 76 HP, 72 ft/lbs. That's with the stock 1200 top end, cams just "dropped in", 185 psi cranking pressure, Rush slip-ons with 1 3/4" baffles, Hammer Impact air cleaner assy.

61 ft/lbs at 2,000 rpm and 60 ft/lbs, 76 hp at 6,600 rpm. Rev limiter was set at 6,700. Pulled smoothly on the dyno from 2,000 rpm. 70+ ft lbs from 4,000 to 5,200 rpm. No big humps or dips. Nice 13.0:1 AFR. It just runs nice.

Now you won't have to make up what numbers mine makes to sooth your delicate ego.

A 1275 kit with 10.5:1 compression with proper squish clearances and cleaned up ports is next. I have switched to 2" baffles since the dyno baseline.

And that's with a 2-5 hp advantage with EFI. More than offsets my small increase in displacement to a 1250. So now we're cam/exhaust for cam/exhaust.
Even on my first dino, the one that printed, 77ft.lbs @ 2300rpm and doesn't drop below 75ft.lbs til 5800rpm but peaks @ 86.5 @ 4300rpm. 65ft.lbs. @ 6500rpm(81hp) where my rev limiter is set at.

Went back a few weeks later after discovering my breathing issue and fixing it with the krankvent, rejetted main, dropped my needle to 2nd groove, replaced my y6 needle jet with y8, tweaked timing mostly low rpm, low map and ran without my AC. From 4300rpm to 6500rpm my torque was 1-3ft.lbs higher. HP peaked at 87(86.8) @ 5700rpm dropping to just under 85(84.9) @ 6500rpm.

You do your 1275 and clean up your heads. I'll tweak my exhaust and clean up my heads. We'll meet on the dyno come summer.
