just finished making an underbody exhaust using a Dsection xr50 can, some GY6 header and the stock header. took about an hour to make with a total cost of $34. the tip of the can is angled so it blows the exhaust away from the tire. sounds great and no back fire.











sounds nasty

Looks cool man.

 

[daddysmut]

thx.

tomorrow my belly pan should be here so it's all gonna get tucked up in there

 

[ZombieGrom]

AHHH that will really sweeten it up. I couldn't get the vid to play, i'll have to try it later

 

[daddysmut]

i think it's my privacy settings...trying to figure it out now

not that i've noticed. it's almost 1am here so i don't want to rip it up thru my neighborhood. i'm going to do the airbox mod tomorrow and reset the ECM

Belly pan should make it look a lot cleaner. Good job on the diy exhaust.

Finally got the video clip to play on my computer, man that thing sounds mean and looks great. Great job. Did you do the air box mod? If so how is the throttle response?

 

[daddysmut]

"after making the exhaust last night i did the DIY airbox mod this morning and took it for a ride (also reset the ECM/EFI). definitely more torque, sounds delicious too!

so stock i would consistently hit 57mph sitting up and the occasional 59mph


after both mods, i'm consistently hitting 60mph and the occasional 62mph


i didn't get to do a full tuck test run yet but pre-mod i would hit 64mph consistently.


oh, i also had cargo shorts on that were blowing up like a parachute...doesn't sound like much but these little things matter on little bikes trying to go fast"

 

[wlorton]

Awesome!!!!

 

[BassOverflow]

Looks killer! I'm stealing this idea when I get mine!!!

I really wanna do this too, but I'm worried about it bottoming out. I don't intend on doing anything crazy with my Grom, but I've had cars with low hanging exhausts (doesn't help they were lowered) and it seemed like I couldn't go anywhere without scraping something.

I'd like to hear how you're doing with it after a few months of daily (or almost daily) driving.
