850 twin pipes

RMK-King · Sep 6, 2018

Here is something we haven't seen from the aftermarket in awhile! It sounds like the 850 responds well to twin pipes. There is a few companies that tested out twins for the 800/800HO but the gains were not worth the price. It will be interesting to see what the single and twin pipe HP gains on the 850 will be.

May not be an 850 but makes some noise

Agreed, all my edge chassis sleds had twins. Just never ponied up for twins in the pro, NPP single was just easier. I did a fair bit of tuning on it so maybe I should have done twins anyways lol. Hindsight.

Yeah, and scavenging.
That comes with the tune in the shape of the expansion chamber and restriction in the exit tube.

So yeah, but you want them to flow well.

Love the ad...order now because they're limited. No HP claims or price. Well they did say incredible HP increases.

I had the comp glasspacks on my edge, too loud! Had NPP build me some bigger ones, perfect! Nice sound but not obnoxious loud and kept the great sound of twins all the way through.

Just thought i would throw that out there for anyone, NPP is great.

My PSI quiet stingers were great back in the day.
Not to loud, but lighter in weight.

BILTIT · Sep 7, 2018

Might be the 910 that made mine louder too.

Slp replied to a question on there face book page about the hp of these twin pipes. They said double of what there single pipe would make. Slp axys 800 single pipe is 9hp. If the 850 single makes the same 9hp, the twins would be 18hp. If slp can get 18hp out of twin pipes for the 850 they would sell like hot cakes.

I'm fearful of the name "outlaw"......what about noise?

I know, I know....I'm lame... but if you had to sit through the USFS meetings that I have been sitting through, you might feel the same.

I also work in the motorcycle roadracing world championships (WSBK) as a crew chief where the bikes hit 100dB--- so I'm not TOTALLY lame.....

How about Cousins? That's how I got my handle.

Edit: Not mine you idiots.

Spaarky and DD.....

I’m more concerned with the fact that “twins” doesn’t establish gender of said twins....

neither of you clarified FEMALE twins....?
