Going to be running PI centre dump pipes on a 700 sx. Anyone else running these. Should be a good trail pipes run at low rpm, lots of torque, quiet. I hear they are down in power from all the others, but running low rpm should have good clutch efficency compared to pipes running at 9000 rpm.Would like feedback from others who are running these pipes.

I have a set they sound nice I was told puts you bout 140 HP with most low end torque generated from any other gyt setups made for them
 
I know that they don't put out anywhere near 140hp, probably closer to 125, from what I've seen on dyno tests that I can find, SLP is the highest at around 132hp, real hp readings. My thinking is if they run at 8100 then they should actually get better mileage than a stocker run between 8300 and 8500.
