Pipes?

[570MC]

Just wondering what single pipe is best to run on a carbed king. Just thinking about putting one on and also if i would have to re-jet or anything like that

most guys around here run speedwerx, they seem to work well, you have to usually go up 2 jets sizes from stock

ive ran both the speed works and the slp. Power on the two feel the same, but the slp fit much better. although i think the slp can is a pos.

I had serious issues with the slp single. In fact my sled ran like $h!t with it on!! Went back to stock and am much happier. I would vote for the speedwerx.

Was it efi or carb?

Speedwerx and get the Y pipe too, it ran much better then the SLP I had... especially after I did this to it

So far I'm really loving my CPI Racing 900 Single and Cutler can combo. My only problem is it's loud as hell... but not as loud as Jaws.

ran the speedwerx had no bottom to it. The SLP is a more aggressive pipe and runs a bit hotter. It hits more on the bottom but also really opens up at the top. I switched to SLP from a speedwerx pipe which seemed to be more EFI friendly, my dad liked it on his sled. I also ran the speedwerx Y pipe and an MBRP can...I went to twins so I have the whole set up for sale. In all reality the stock AC pipes aren't a bad pipe to begin with.

As far as jetting goes, I dropped the neddle down one, added 4 sizes for the pipe and another 1 or 2 for the manifold. I ran at 7-10k and didn't have a problem.

I had the same experience with the Speedwerx single. I have been running a ceramic coated stock pipe with better consistency than the Speedwerx and no drop in top end.

So then a modded Bikeman stocker might be the way to go? You can have it ceramichromed and dump the cat shield and insulation? Or just leave it be? I would hate to have nothing to go back to if it turned out to be a flop!

Thanks

04 king, D&D y-pipe, stock pipe, SLP can modified for front dump, 360 mains,50 pilot,#4 needle, 4000-7000ft. I'm happy Power claw and front post were the best mods.

I have a 01 with the 1010 kit on it and i run a speedwerx Y pipe, fat daddy pipe, and their can and it runs awsome and very consistant for me, but i run 0-3000 ft.

I am not familiar with the Bikeman mod but I had a local shop coat my stocker and ran it without the shield with great results. I just picked up a D&D pipe to try but only for weight loss. I was very happy with the coated stocker and will go back to it in a heartbeat if I don't like the D&D.

The only thing I don't like with the aftermarket pipes is you have to jet up! What kind of mileage do they return over the stocker? if a pipe is tuned for a higher RPM I would assume the same?

I had an slp sing. on my 03 could never get it to run right. I took it off and put slp twins with slp porting and bored carbs and it runns great no messing with jets after i set it up.
