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.

If you are expecting something dramatic, don't waste your money. You'll get a small bump in power, but 5-8hp is going to be negligible if noticable at all to most people's "butt dyno".
No, it absolutely does not sound "tons" better. It does increase the sound a little and I liked the changed, but it isn't dramatic unless you put it in combo with other exhaust mods.
I was very pleased with my bypass pipes, but I had pretty limited expectations of what they would do for my car. I agree with Boxtaboy that the lost weight of the factory cats may very well be the best part of this modification.
After following a few of your posts related to this I fear you will end up disappointed with these if you don't add them in combination with some other items.
Good luck
