Today I had a customer with a nice shiny new 2012 CVO UC roll in today with our outside temps well past the 100 mark. After a few base line runs, I installed 2.0 cores in his stock mufflers
and bolted on our New Sportpipe. Rolled it back in the dyno room and did a couple of VTune runs, and a dozen wide open pulls to get the AFR straight. Stock ECM was
accessed with TTS Mastertune. Results showed very early TQ crossing 100 FT pounds by 2400 and peaking almost 1000 RPM earlier than stock. Our afternoon temps peaked at 106 today.
Not the best conditions for dyno testing, but we still managed to make some decent power from a very economical build.

Special thanks to Bob Watson of Tucson Arizona for braving the heat and riding with a Fullsac!

Thats a pretty nice gain. 

Do you have the Sportpipes in stock, or is there a waiting list?

Thanks

We get a surge in inventory every Thursday as our coater delivers X Pipes and Sportpipes once a week. All the product seems to disapear by Monday.
Call Alice to see whats available. Sportpipes are a week out at the most. There may be one available today.

Thanks for your interest!

Do you have maps for the Dynojet Powervision or do you just deal with TTS maps??

Sorry, I only program with TTS Mastertune.

Steve, do you have a chart for the same setup but with a B or C x pipe?

Thanks

Sorry, I don't have a back to back comparison between the XPipe/Sportpipe done on the same bike other than the shops 103.
On the individual stage I CVO builds we have done, the X Pipe and Sportpipe are consistently making very similar numbers
among the different bikes. On the builds with cams, the "C" Xpipe is still the heavy hitter.

Steve... What is the difference between the B and C pipe? I looked on your web site there is no mention of it there.

My apologies for the outdated website, the new one is getting closer.
The B and C XPipes are very similar in design and performance. The B Pipe is stepped from 1.625 to 1.750. The C Pipe is all 1.75 primary's. One of the most critical areas
of any header is the size and angle of the collector. The B, C and new "Sportpipe" share identical collectors. Your splitting hairs between the B and C Xpipe at the 100 HP level.
The smaller 96 and 103 stage I builds in the low 80HP area will make earlier TQ with the B. Above 100HP the C Xpipe will start to show a slight advantage.
We have independent dyno charts with the B Pipe making 128 HP on a 120R and 125HP with 141TQ on a 124" build. These are the motors that would see a nice gain
switching to a C Pipe. If your running a B Pipe on the typical CVO 110 with cams making around 105 HP, your not going to feel the difference switching from a B to a C XPipe.
We are flattered that others have seen substantial gains with the C Pipe over the B. Our in house testing hasn't been quite as generous, or possibly our combination
of parts hasn't shown the gap in performance that others have experienced.

Thanks for your interest!

What kind of gain are you talking about? Do you have any data to compare the same motor using a B pipe vs. a C pipe?

The B Pipe has a smaller inlet flange than the exhaust port on the 120R. That's why we made the C Pipe with a larger flange and primary to match the huge exhaust port.
It stands to reason you could gain a few HP or more on a 120R with the C Pipe over the B. Other are claiming this on the 110 motors already.
I don't have any in house back to back dyno data on the big cube motors done in my shop to confirm this. Just me speculating that running a huge exhaust port
into a smaller hole may be less than optimal.

Yeah, ran into that reversion aspect on a SB Chevy I built using 1 5/8" headers. About all I could do at the time was radius the edge of the header pipe but then I wasn't really hogging out the ports. More of a port gasket match deal. C pipe sounds good on the big inch mills. 

[Depdog]

So on a 103 with a stage 1 (better high flow A/C, Slip ons, TTS) the Sportpipe is within a hp or two of the B or C?

I'm sorry if I am being redundant, just trying to make sure because for me the header is the last bit I need and a big chunk of change to make the wrong choice.  Unlike some of other folks, my budget is T I G H T right now and mama won't take much more before she pops her cork

Do you maybe have a chart of the Sportpipe and B pipe on the same 103 motor? In a perfect world it would be a stage 1 modified 103.

Steve, thanks a ton for you time on here and the phone in regards to my questions.
