i've read claims of 8hp and more torque - which some people could feel via the butt-dyno.... just curious if anyone here thinks that on a 2.7L car, this mod would actually make the car feel quicker?
I'm in CA - so I need to stay smog legal. Pelican parts website says the secondary cats are unnecessary, that it won't throw a CEL and that it will still pass smog. That true? why did Porsche put those cats there if we don't "need' them?
does it sound tons better once these cats are gone?
I'm also thinking of putting the Pedro techno-torque onto my car - wondering if the combo of that plus the bypass pipes might give the car a little more zip!
thanks.

Having two sets of cats is like having two more big toes ! They serve no purpose but to satisfy "Uncle Sugar" and his OBD II requirements. Get rid of them, and free up some excess weight and perhaps create a better flowing exhaust while retaining some needed back pressure.
