I have just finished custom headers + system for my BMW650 (twin).
Have dyno sheets from tuning afterwards. 18% more torque, 13% more power. Polished 304 stainless. Sound whilst cruising nice, wide open throttle has really nice bark. Better fuel economy. Have pictures will post when learn how (new to forums...) Saves 4.5 kgs in weight.

Sound clips would be most excellent!
..... Pictures too
