Single Shot questions - 3000GT/Stealth International Message Center

Hi I was wondering if the single shot will bolt up to the cat (race pipe in my case) or does it replace those and go directly to the downpipe?

Thanks.

It will bolt up to the cat. Hence catback

One more thing will I pass emissions with this and a test pipe? How about if I take the test pipe off and put my old cat back on will I pass then?

do you still have pre-cats, and are they gutted? If you just have a test pipe then no you probably will NOT pass emissions. If you put your main cat back on and drive it around and get it heated up so the fibers expand in it(if you have gutted or no pre-cats) then you should be fine, just make sure you drive it for 20-30min pretty hard before you get it tested.

What do you mean by precats? I know theres a cat on the front of my downpipe thats attatched and no I didn't gut any cats.

That would be your precat. As long as your cats are in place and fuctioning the cat back wont make you fail emissions.

Like they already said it's just from the cat or testpipe back. Chances are you won't pass emissions for testpipes but most people keep their stock cat and swap it back on when that time of year rolls around.
