Which header to install with stock muffler?

The only thing I'm not keen on about the Versys 650 engine is that it just gives up past 8500 rpm with 2000 rpm left on the tach. I like winding out my bikes when the mood strikes so it would be great to get more top end out of it.

After searching all the performance mods it appears changing to an aftermarket header like arrow pipes would open up the upper rev range of the Versys 650 and that it fits with the stock muffler.

I'd like to find the best quality header for the bike even if it makes a bit less power than the arrow pipes. I don't want the pipes falling apart 10k miles after install. Ideally, I'd like to just bolt on the new pipes without needing dyno tuning or ECU changes.

Is the arrow header a quality part? Will it achieve my goal?
Or is there a better header out there?

Thanks!

Even then, the Versys engine is just not meant to breathe up high. You'll make more power swapping in a Ninja 650 engine and ECU than with a full system + power commander, and the fist option is probably cheaper too.

BTW, I'm assuming, from your signature, that you have a 2014. The 2015 has the same engine as the Ninja 650.

With my Muzzy header and custom Magnaflow silencer with Yoshimura outlet, my 2007 pulls strong up to the 10,700 rpm rev limiter... That's without any aftermarket fuel management system.

You'd do better with just a good silencer, than with a performance header and stock muffler/catalytic converter.

I am grateful for the replies invader and Susser Tod. You are correct. My bike is a California smog equipped 2014 Versys 650.

It looks like I need to think about this a bit more. One consequence that concerns me is that my wife would be unhappy riding with me if the Versys was much louder. We ride together most weekends which is more important to me than increasing performance. I also like to ride for 3 or 4 hours at a time and remember being unappy with supertrapp "silencer" on a Yamaha XT600 I owned many years ago. I'd get headaches after >2 hours listening to that raspy nasty sound.

Invader, how loud is your mangaflow setup? I had a mustang with mangaflow exhaust and it wasn't what you'd call quiet. I had to upgrade the stereo to hear anything but the engine when driving. No hands free phone option worked over that level of noise.

Thanks again!

When I got my Muzzy full exhaust system with megaphone silencer, it was ridiculously loud and brash, even with a custom baffle which helped a lot... The Muzzy header's collector diameter is much larger than stock. I used a 2" in/out, 14" long Magnaflow with 2.5" core. It sounds great, and is not too loud at all. I'll try to get some audio clip.

By the way, make sure your air filter is clean and not over-oiled.

Pre-welded Magnaflow with the outlet cut down to the 2.5" core, and Yoshimura 1-5/16" quiet insert:

IF you want your V to 'work' better at higher RPM, try a Ninja 650 header - they do NOT have the 'balance' pipe between the sides (which is there to lower the range where the torque is), so that should 'move' your power higher in the revs.

I have thought it over and it sure seems easier to be happy with the bike as is -> at least until the warranty expires. I do see that changing the upper end performance is not a simple bolt one part on and you're done proposition. The bike is about 3 months old and I admit that taking it apart is the last thing on my mind right now. Riding it is pretty much all I think about.

I do like the mangaflow setup invader has shown us in previous posts. From a web search, it seems that the Muzzys header isn't available for Versys on their web site anymore. Also strange is how all the headers I have found for the Versys 650 list '08 to '13 or just the '15 model year for compatibility. It would appear my '14 Versys 650 is unlike all other years in some way that I can't identify. I remember reading that the '14 had a bump up in power along with the ABS but now I can't find any evidence of the engine or exhaust being unique to 2014 anywhere.

There's been a lot of great info posted on this thread and I will keep it in mind should I ever feel bored with my bike and in the mood to wrench on it.

Putting a 1st gen Ninja 650 intake cam in your head would help too, along with moving the Versys intake over to the exhaust side. Then replace your stock head gasket with a Cometic for more compression. The cams will allow for some more breathing to complement the extra exhaust flow. Then you'll have the top end the original Ninja 650 had.
