Hi guys

i just want to get an opinion about X or H pipes

im having a 370z with Legamax HKS Cats with H pipe + FI LTH + Stillen 3rd G CAI

well i feel that im losing power, i mean before installing the stillen and FI, it was faster than now (old mods was HKS legamax, test pipes and takeeda short arm CAI )...

so if i changed the H pipe to X pipe will it differs ?

please HELP

Have you tuned the car? With all those breather mods the car will feel much slower light to light because you lost a lot of your low end torque.

a tune will help a lot. i picked up 22lbs tq at 4k after my tune.

Not sure what kind of dyno was used, but its in the ball park. You need to get a tune as everyone above said. A 10 to 15whp jump is generally realized.
