QUOTE(Kadett @ Dec 5, 2006 - 8:36 AM) [snapback]507915[/snapback] On UK forum it is said you would gain 15 BHP and 15lb/ft torque. + you save about 10 kgs of weight. Stock DP is about 12-13kgs compared to 2-3 for a Aussie DP  That is a XS/SS downpipe, just so you know!!!! Did its job for about 3 months before it tore apart. With BPU 2nd gen engine. did you use the support bracket on the bottom? -------------------- 15PSI - 30MPG - Megasquirt Tuned
