There still has been no proof from any of these company's to the gains their parts have.You would think one company could give some rel results or maybe there's no proof because of very little to no gains.Just saying

Seems plausible. Maybe part of the reason there is still no dyno results for the 16s.

I don't believe any one can feel a 2 to 6 Hp increase riding unless they can feel a pea  under their mattress.

I guess it just sounds faster.May as well chrome it and put some monster stickers on it while your at it.

Most of the guys here with 1200s who have them running strong, have all had to go with the full setup to get them that way. While any single part of the full setup might not make alot of HP on its own, it seems that all the parts together bring the power/speed up for the 4tec.

 

Many guys have radar and gps numbers to prove it. I think that is why dyno numbers on the header alone are not impressive, and even moreso on the XS 4tec, as it needs a reflash to get the proper fueling when adding a header......just too lean to make anything but heat it seems with the stock map.

Looks the same as the previous headers, ran one last year, not a stepped design again, good wide open header, the stepped headers are reported to respond better for trail riding. It was hard for me to notice any difference over a mbrp because it was on a different machine and not both on my 16

A lot of these speed gains could also be credited to a more aggressive clutching.If someone with the mods ran stock clutching how were the results?This would be a interesting test.

With clutching and the header, mine barely ran faster than stock. It wasn't until the ecu flash that I really saw the gains.

That's what I was saying....If you can only tell by radar and gps then is it really worth it unless you are racing and 10'ths of a second count?I know some want every hp possible but where is the dyno proof of where the rpm's  are for the 2 hp increase?At 5500  or 8500.It may make less at a higher rpm and slow you down.  Seat of the pants corner to corner trail riding I need at least 10-15 hp to "feel it" which means at the very least starting with good traction first,a  reflash and clutching.

I have the XR so it may be a bit different, but judging by how it feels and how it compares to a stock 1200 and up against 800etecs, I would say if you do all the mods, it’s an honest 20hp increase. I’ve never had it on a dyno, and I don’t need to. It’s noticeable the first mile you ride mine compared to stock. I’m not a drag racer, I did the mods for corner to corner speed trail riding, the wins when lining it up are just a bonus! It has more power at every rpm range and is a blast to ride now. An added bonus is I still get the exact same mileage as the other 4 1200s in my group.

Nickski what did you do to your XR? I have a 2014 1200 Renegade and your results are exactly what I am looking for.

Nickski what did you do to your XR? I have a 2014 1200 Renegade and your results are exactly what I am looking for.

 

First stage:
MBRP header
PB-80
Cudney clutching, CR9 helix

 

This was only slightly faster in a straight line, but much better clutching for the trails.

 

Stage 2:
ECU flash, 9000 rpm limiter, clutched to 87-8800
Muffler mod
Went from 96 to 120 studs

 

This made a world of difference! Much faster than before, but still needed more traction.

 

Last year tweaks:
Dupont slides
144 studs
More venting on the clutch side.

 

Hooks up better, clutch is cooler, but still hot.

 

This year:
Wrapped the header and sealed with silicone spray
Adjusted the play in the throttle cable
Added ½ puck weight to the PB-80.

 

I’m hoping to pull the same RPM with the little extra weight, clutching should be much cooler with the header wrapped. My hope is the combination of cooler intake temps, cooler clutch temps, and throttle opening a bit more will result in a bit better performance. It’s already to a point where I’m very happy, but minor tweaks can add up.

Thanks Nickski greatly appreciated. I have been in contact with Cudney and trying to decide if the Pb80 and secondary kit are worth it if I don't do the header. Basically don't want to be disappointed with little to no change by spending 800 or so when an extra 400 could make all the difference. Budget is always an issue is there a minimum you would suggest doing to see noticeable results? Thanks again.

Clutching first and try to get your rpms to 8400. I wouldn't spend the money for a header unless you plan on doing the ecu as well.
