do you need the cat converter for an 88 na supra and is 2 1/2 big enough pipe

I think all cars need the cat converter and all so that you can meet U.S. emission standards.

In wisconsin if your car is 20 years or old you can register it as a classic and then you never have to do emissions again. I'd maybe explore that.

If you live in IL, I would look into emissions because Im pretty sure that it is if your car is 95 and older(or unless it has the OBD II computer found is some 94 and 95 cars) computer then Im pretty sure that you take it one more time and that is the last time. I also need to look into this because I saw a article on it awhile back this year. I think it started feb 1, 2007.

About the cats. You can get a high flow cat and still pass emissions and not loose HP or you can get a test pipe. I have one cat in my turbo supra and one test pipe but soon Im changing the DP so I will have no cats but im also be running premium gas.
