Same here, no problems at all, with SilMotor and spark midpipe!Jones said:I have a '06 S2r1K and have never experienced a surge. I'm running a Sparks full system and open airbox. When the motor was new and under 600 miles it would hunt for a smooth idle once in a while when the motor was cold. But that all cleared up after the first service.

I get a little popping on decel when the rpms drop below 4500 rpm, but that's from the O2 sensor leaning out the A/F mix in that range.
