Anyone running CPI Racing Pipe

[sledhead ut]

Wondering if anyone has a CPI Pipe on their sled? Claims to have a 8-9hp gain with a 5 lb. loss. Sounds too good to be true. Let's here your thoughts and comparisons.

i've been riding my 163 xp with a cpi single and can for over a month....total loss in weight was just over 15 lbs....cpi is being modest about the 8-9 hp....the dyno sheet for the pipe, can and two flo-rites in the air box was 12 hp....it pulls real strong across the entire power curve...i use 500 main jets and shim the needle with the purple shim from the kits that you see advertised in the mags...kicks the stocker i ride with every where, especially in acceleratiion uphill in the deep.....clutch to pull at 8100-8200....the d8's don't have a chance

I'm already runing HPS can, milled heads and 2 Florites in the box. Have you done any clutching? I was planning on clickin to a 4 this weekend just to see the difference. OH and I forgot I have a HOTDOGGER.
