Hello all,

I will be having Lee install a new exhaust system on my 12 shortly. As money comes in of course. My first thought here is to go with a brocks. Absolutely loved it on my zrx.

Does anyone here have any experience with hp/trq numbers for a Brocks on the ZX12R? Or does anyone have comparable numbers on any other suggested full systems? Any comments are appreciated.

You just missed a full exhuast and PC on the other board. I haven't checked it in a day or 2 but may still be there.

I have been super happy with my Arata... but I don't think you can get them anymore. When I put it on in 2007 I took it to a highly known tuner who has a quite conservative dyno and I made more HP than any other 12 that he had done to date of 12's that had only exhaust, PC III and filters. Now I have a fresh 1290 and the Arata still does well. Made peak power starting at 10,400 and it goes flat to the limiter at 12,200. So it makes peak HP for nearly 2000 rpm. My .02.

And for those wondering, the SP5 pull is an oxygenated fuel. Think along the lines of MR9/12. Very strong numbers. I have a Brock's for my 1287 12R....will get back to that project this winter! :)
