Cats or no Cats
Getting ready to buy a set of Melrose headers and x pipe. I'll be running them with the stock mufflers, but was wondering if anyone else out there has ditched the cats? I live in Ohio, and they stopped emissions testing last year, so I'm thinking why not just leave the cats off? Does this create any other issues? I would think the flow would be better without them, plus they just add a few hundred bucks to the price. Feedback?

I've got Corsa Sport and KOOKS with the offroad x-pipe with my setup. Very loud but the downside is the odor is nasty as the result of no cats. Someday I may convert back to high flow cats, but not any time soon.

To cats, or not to cats: that is the question:
Whether 'tis nobler in the mind to suffer
The slings and arrows of the EPA,
Or to take arms against a sea of tuners,
And by opposing end them? To gut: to have increased performance;
No more; and by performance to say we end
The ego-ache and the thousand natural modifications
That fiberglass and aluminum is heir to, 'tis a consummation
Devoutly to be wish'd. To gut: to have increased performance;
To perform: perchance to pass another vette, ay, there's the rub;
For in that passing on the straight what dreams may come
When we have gutted off this mortal obstruction
Must give us acceleration: there's the respect
That makes quickly of so long an otherwise pass
For who would bear the waves and cheers of fellow vette-owners,
The government’s wrong, the proud man's contumely,
The pangs of despised modification addiction, the law's of lateral acceleration
The impatience of hesitation and the fumes
That patient merit of the worthy secret mod,
When he himself might in noisiness make
With a bare exhaust? who would fardels fear,
To grunt and sweat harnessing a terrifying flame,
But that they dread of something coming up after
The undiscover'd fuel economy from whose purchase
No gasoline buyer is ever rebated, puzzles the will
And makes us rather bear those middle east profiteers we conceive
Than fly past others that know not of our secret?
Thus conscience does make stronger to defy the will of governmental dogma;
And thus the native hue of the vette owner resolution
Thou competitors are sicklied o'er with the pale cast of thought,
And enterprises of great flow and moment of inertia
With this regard their currents high turns awry,
And gain the name of action. - Winner are you now!
The fair Corvette! Nymph, in thy orisons
Be all my modifications remember'd.

Psilocybin/Psilocin Mushrooms
At low doses, psilocybin causes simple feelings of relaxation, physical heaviness or lightness, and some perceptual distortions (especially visual). At higher doses, more physical sensations occur, including lightheadedness, numbness of the tongue, lips, or mouth, shivering, or sweating nausea, and anxiety. The symptoms may appear 30 to 60 minutes after the mushrooms are eaten and can last about four to six hours with a several hours long "afterglow".

To the OP - my .02 is to keep the cats. Never know when you might end up suffering the slings and tasers of LEOs in a state that DOES have emissions.

For those who post that high flow cats only cost 3 to 5 HP. Is this from actual experience with the LS2, headers w/with out cats? Or are you just relating something somebody else said?
Reason I ask is because on my last Corvette, a heads/cam LS1, when I replaced the stock cats with 3" off road pipes, I gained 15 hp and 12 ft lbs of torque. Now on my Z06, I added the American Racing Headers with high flow cats.
