It idles at 850rpm, and the exhaust is a full TTI with step headers and 3" tubing with an H pipe. It does have a set of 12" ovalized megaphone tips. They really sweeten up the sound. Same concept as horns and musical instruments take advantage of.

I am a strong advocate of well-built 200R4 automatic overdrives with lock-up, high stall torque converters. Its the best transmission I've ever driven, and feel/acts like a 5 speed automatic.
