you will lose power... DO NOT DO

the exhaust won't flow well at all... if you think about it... the gasses will actually tumble from all the extra volumein the pipes...

so 2 1/2 will suffice

i guess it might, but it will run like ****.

If you want to be loud just pull the cats and get a loud muffler.

Yeah I've heard that you really only need like one inch diameter per 50 horsepower or something like that, 3.5 inch exhaust wouldn't do any good, only bad.

you could find a private inspector...

You remove them cats and have a non legal CA emmissions vehicle... take it to a private inspector... fork over some $$$ and get that stinkin sticker...

Or get high flow cats... they are the same thing but the holes in the catalic material are larger...

Or... do whatever you want... but save your stock stuff... so when you go to inspections you can swap back to stock...
