Exhaust, tuner, ai filter mods. Good power?

Has anyone done all of the mods and does it add enough power to be noticeable or would it be a waste of my money. I know I could use the money as a down payment on a more powerful machine, but I like my teryx!

Tag. Done the tuner VFJ. Not much hp gain but limits removed a big deal to me. I would do full $1000 exhaust if I knew 100% it made large change. I am considering clutching for responsiveness. VFJ older dyno runs with full muzzy did show large improvements but I need more, seat of pants testimony.

A tuner or ECM reprogram is nice because it gets rid of the speed limiter and raises the RPM limiter. I would recommend skipping the exhaust and instead use the money for a clutch kit.

I plan to do a clutch upgrade after few thousand miles and I dig into belt. It is a bit of work tearing down. What I don't like about exhaust is more possible noise? Where is the hush quiet core type system?

Muzzy used to have the quiet core available for their exhaust systems, unfortunately they are no longer in business. They were quieter than the wide open exhaust, but still pretty loud at WFO. It was music to my old ears, but it can be annoying to the machines behind you in a group trail ride situation. The last full exhaust we put on a vehicle was a Trinity, and I think it was louder than the Muzzys.

from somebody that has done all three, by far the biggest "seat of the pants" performance improvement is a full VFJ clutch. a tuner really didn't do much for me other than the raising of the limiters tho a slight low end improvement is there. the tuner improvement outside of the raised speed limit is so small that after I drowned mine I left it off and am back to running stock ecu tuning.


my friend and I have basically identical machines and anything I do to mine he does to his, all except for the exhaust which he couldn't find due to MUZZY going out of business. same clutching, snorkel setup, tuners, etc on both machines and mine will just barely pull on him while accelerating, and I mean BARELY. for proof outside the seat of pants-o-meter with tuners on his machine tops out at a hard 64-65mph and mine is a hard 65-66 and will bump 67 occasionally but usually sits at 66 for no longer than I care to run WFO which isn't that long.


FWIW I like my MUZZY but they do get a little loud when youre trying to be quiet and if they go under water and get wet on the inside they are extremely loud, comparable to an HMF IMO

Clutching will be the most noticeable change you can make. Exhaust will just sound better lol and maybe make you feel like its quicker haha. The only limiter I want to delete is the DIFF LOCK 15 mph crap, every time I hammer a mud hole or get steam for a long gnarly hill climb my machine just bounces off the diff lock and it pisses me off

The rules for the Teryx V-twin is the same as any internal combustion engine, it is an air pump, the more air that goes through it = more H.P. A full dual exhaust system is going to flow more air, and the addition of a controller allows you to adjust for an optimal timing and Air/fuel ratio, along with raising the rev. and diff. lock limiters.
