17 FX450 Slip On and Remap from Tokyo Mods

For anyone who is looking to get an exhaust for their 250, 350 or 450, take a hard look at going through Tokyo Mods. The stock exhaust is extremely restrictive (and sounds like an XR50). Putting a new exhaust, as has been noted all over the internet, makes these bikes run super lean as they already come from the factory a little lean to begin with. I was going to adjust the TPS after installing a slip on, but that is a bandaid fix. I looked into Tokyo Mods based off of a few recommendations from some of the bros on this forum. Incidentally, they were offering a deal I couldn't resist.

They are currently running a deal with their exhaust sales in which they will do a free remap with purchase. I bought an FMF Ti slip on and had my ECU remapped for $399 shipped. That's a pretty good deal considering that RMATV sells the same exhaust for $450 and a remap on its own would cost another $100.

I had them map for just the slip on and a 50/50 mix of pump gas and VP 110. The difference in throttle response and low end is astonishing. I haven't gotten to open it up too much yet as everything came in the mail last night, but I will go ride tomorrow and give a more detailed report. I am pleased so far. The bike seems to start a little easier as well. The icing on the cake is the FMF slip on is half the weight of the stocker.

The customer service from Tokyo Mods was excellent. I highly recommend them.
