Yeah yeah yeah, and I'm killing the bunnies and taking the ice caps away from the polar bears. LOL. If I cared about that junk I'd drive a Volt or something (cause I sure ain't driving a Prius).
That Hytech unit looks legit! But I still wonder how long it will hold up.

I guess I'll try the stock cat then.
Honestly I'd rather lose 20whp than have my wife smelling like gas and cleaning by bumper with simple green twice a week.
Maybe I'll do a tune on a test pipe and stock cat and report my results.
Also, you can probably tune for a test pipe and put a cat on and be okay, but not the other way around. Going from the cat to a test pipe will change the volumetric efficiency of the engine and make it run lean. Depending on how lean the turner goes with the A/F, it could grenade your engine.
I had two catalytic converters on my 550+whp SHO for 9 years before I sold it. I never melted them or blew them out.

Yeah a little simple green on the rear, but honestly you have issues if your smelling fuel, or worse smelling on you after. A tp just isn't that bad with a properly running and tuned car. If your burning oil, well thats a seperate issue, you will smell it. But mostly at a stop, its everyone else behind you that gets the joy.

The stocker should get you there . I am sitting around 400whp with the stock exhaust/cat with a 12psi Vortech. No smell or soot on the bumper . I am however giving up some free power . Its all good though . I have been tempted to put on a test pipe for a quick dyno pull but i don't know if it's really worth it .

Get a good tune and a test pipe, and you should be fine. You may also want to check your injectors/fuel pump if you're smelling gas in the cabin.

My last s2000 has a turbo setup with test pipe. Smelled Bad.
My last car was a 996 turbo. Modded to 600whp/575wtq. No cats. Smelled bad and left marks on the bumpers.
I don't think I want to chance it again. Especially with the lack of good tuners up here in canada.
