well i added an HKS SMF intakeand i gutted out my cats. but i also took out my Y pipe..

would it be running from just the headers and lose all back pressure and low end torque? is there another way i gain more power w/o sacrificing my low endtorque? and more info on engine tweaks?

 

What is this low-end torque you speak of? If you mean "low torque" then your car came from the factory with that already installed.

lol

Back presure isn't a consideration on rotory engines unless its N/A and needed for the 6 port activation. Search and you shall receive more engine tweaks than you can shake a stick at.
