    Hi I Got an aftermarket exhaust and I did the DIY air box mod. I know when you change the exhaust and put a different air intake like a Chimera Intake you need a reflashed ECU or something like a Boosterplug. Now I am a bit lost cause I don't know/can't find if the DIY mod does enough to get...

    I have not posted my build here so I figured I would throw it out there for everyone to see, Ask questions and make fun of my purpleness :). I have learned a lot in the progress of my grom build and wasted a lot of money to the point where now I could build an engine blindfolded. I knew nothing...

    Hi everyone, I wanna change the exhaust on my 2018 grom but I'm finding it hard to find a street legal exhaust. The only one I have found is a black widow 300mm exhaust which in my opinion looks too big for the grom. Anyone got any ideas?

  12. Grom How-To's and Guides
    I recently installed the AR Mini Exhaust on my 2018 Grom. I'm very impressed didn't expect to even notice a power difference but being a small guy I guess it helped. One problem I ran into which pretty much every one has with the Aodonly Racing Exhaust is that it's really loud even with the...

    So I just bought a 2018 Honda Grom and I have began modding. First things first I wanted to get a high-mount FMF exhaust and a Chimera Intake. I will most likely end up getting the Aracer RC Mini Plus2 ECU. My question is, should I buy the FMF from steady garage and have them weld the O2 sensor...
