Final Exhaust Mod with Youtube clip.

[BRatigan]

I finally finished my exhaust mod to my XB12X Uly. I have a thread from two years ago when I modded an existing Special OPS pipe that was super loud by repiping the interior with 2 inch pipe. That worked well but I had a flat spot at 3500-4000. I think the pulses were fighting one another. I since added another outlet similar to the race pipe "concept". I also removed the packing from the from bullnose of the pipe. There was a ton in there. I finally bypassed the exhaust valve by rubber hosing the cable under the airbox after disconnecting from the servo.
Throttle response is now immediate and the rumble is awesome. Here is a link or video whichever takes.
