Thanks for putting in the work so we all can have accurate info and can make informed decisions.

 

thanks for the info

 

Updated a few more!

 

Thank you Joey!

You rock!

 

Updated with rpm header

 

Updated with AA header

 

WHICH HEADER IS BEST? I SHOW YOU IN A POLARIS RZR PRO R FULL HEADER COMPARISON

 

Great info. Love to see you guys test some of the muffler options next.

 

Updated with 3" muffler and various header combos
WHICH HEADER IS BEST? I SHOW YOU IN A POLARIS RZR PRO R FULL HEADER COMPARISON WITH 3 INCH MUFFLER

 

I think I’ll just put a better muffler on the factory header. Looks like the best power gains overall.

 

Looks like the stock header with a free flowing muffler would be the way to go for trail riding...and the RPM header and free flowing muffler would be good for WFO dune riding.

Is that what you guys are seeing?

I think you pretty much nailed it!!

Looks like I'll be leaving the stock header on and probably doing the RPM muffler.

 

mine has never been over 7000 or 40 mph I’ll keep mine stock until somebody make a QUIET muffler.

 

Thank you Joey for all of your hard work to bring us these tests!

 

We do make a pretty nice muffler that is not ear piercing and has a nice throaty tone too.

It’s a little late but it would have been interesting to put a db meter in the dyno room for each set up. that would be a number I would be interested in seeing.

 

Will there be a muffler comparison with the stock header? A lot more mufflers out there than headers. If you do please put a db meter in the room. Even if its just a cell phone app. I know it wont correspond to outdoor sound levels but it should at least give a comparison one vs another.

 

Yes I did a muffler comparison for Free flowing 3", stock and evol

 

Great information and good to see how the various brands of headers stack up - Polaris OEM being pretty impressive. Seems a 3" flow through muffler on OEM headers with a tune, is the best value proposition - then add Bikeman cams and you have an amazing package, with a big power improvement for $3k. Keep the $100 per hp coming Joey! Typically when dealing with NA motors, that formula ($100/hp) is not going to work.

Looking forward to adding more power this summer.

 

Fantastic information Joey! Just what I was looking for. Really appreciate the unbiased testing and hard numbers in an apples-to-apples environment. Question, that lag on the bottom end with the aftermarket headers, can that be tuned out or is it just the way it is with the flow of the header? It seems the bigger the gain on the top end, the bigger the dip on the low end.

 

A well made header will make about the same power but by changing the primary tube length you can shift the rpm efficiency window around.
