undertunnel exhaust

[TurboMatt]

I am going to be putting a undertunnel exhaust on an Apex that I will be picking up shortly. Can it be run without ECU mods? What about out west 8,000-10,000 ft.?

I also have an Excell Mtn Lite under tunnel. I like it. It's a little bit loud, and the install was a pain because I had to fabricate a cover for the muffler hole (there's lots of pictures on TY). I also have the small miss in the mid-range, but I vented my airbox and it's a little better. I ride between 9000 and 12,000 feet.

I have a Performance Lite, by TJ’s Sports. I get an occasional miss around 7000 RPM. Looking at an RB3 control module to fix it and add a few more HP.

chuckr, no worries, none have it and no one checks, unlike on Dirt bikes in CA

Yes you dont get them with one but you will not need it for a sled up here.
Good idea to run a pc3 with it as you most likey get a miss.
