SIG's 2021 YFZ 450R Special Edition in for upgrades! 

This PC5 is using one of our Dyno tune files. PEP is a good option if the customer can wait on shipping but if they want to keep upgrading over time the PC5 or Vortex is a good option that I can tune inhouse.

Nah vortex is the only way to fix the quads bog and throttle response

Hey, we are located in Woodstock GA. Just message us on Instagram or Facebook @ Limitless Powersports

Most exhaust companies say you can get by with a full exhaust and no tune but for best results add some kind of programmer or tune. If you modify the air box at all like remove the lid, K&n style filter, or Fuel customs intake you for sure need a tune. I have PC5 in stock just message me on Facebook

if it's carbureted, yes you should re jet a little more richer. it's is fuel injected you'll need a tuner.

Can you re type this?

Unfortunately Empire did not accept out dealer application but here is a link to their website empireindustriesinc.com/product/empire-industries-gen-2-exhaust-2010-20-yamaha-yfz-450rx/

Sig will be back. I am sure of it! We will have stage 2 cams, FCI intake, and a New Limitless Dyno tune file waiting on him!

Hey, I have not heard the monster in person. As far as empire oval & dasa classic. I would say I like the dasa tone better. Loud and raspy if that is what you are looking for.

@@limitlesspowersports Thanks for the info, I'll take it into account.

@@limitlesspowersports It is that I have a yfz and I would like to install a pipe that sounds hard and gives power to the machine. One question, which computer is better Vortex or Power Commander ?

@@tucubassfishingpr1056 Ether is fine. I will say with the PC5 you will need a custom file like we offer for $100. The files on the website I did try and did not like any of them for big 3. The Vortex is great if you have the budget It comes pre programed with 9 maps that are adjusted with dials by 2.5% per click. The vortex can also be dyno tuned like this PC5 it gives you a lot more control. Things like disabling roll over switch but your tuner must have the Vortex plug in and map.

@@limitlesspowersports Thanks for the information, I think I'm going to install dasa pipe with vortex computer and intake fuel custom's

Hey, which part?

Most aftermarket exhaust will pop like this when revving it at a stand still. This one is tuned as well

I used our inhouse dyno file we have for big3 set up. All of the Maps free online after testing I found do not eliminate the bottom end bog. We sell the map for $100 for PC5 just message me on Facebook if you are interested.

@@limitlesspowersports What do you mean by Bog

@@dylanwilliams4612 Yfz 450rs are known for having a bottom end hesitation from the factory. If you add a pipe this can be more pronounced. We tried the files on PC5 website but none did what we wanted to the low rpm performance so that is why we went to the dyno and made out own map that we sell to customer for $100

This is the Gen2 standard length by Empire

Yes, Auto Magic Red Hot is the degreaser. Check out our how to wash an Atv like a pro video.

450s top out around 76-80mph. Intake and exhaust like this get you to top speed faster not increase your top speed. To increase top speed you need to change your gearing
