Hi flow cat?
Standard cat?
Test pipe?

Benefits of each.
Legality as far as NYSI.

Any experiences with certain products?

[DougFresh]

Or direct to me towards some literature on it.

Test Pipe: No Cat. Highest Performance. Loudest. Will not pass NYSI (aka illegal).

High Flow: Better performance* than standard. Louder. Will pass NYSI most of the time and therefore legal.

Standard: Lowest performance*.


*I've had a high flow cat on a 3" GHL downpipe and an oem one. I didn't feel any noticeable difference in performance. I would imagine you would only notice a difference without a cat. That high flow thing seems like a bunch of BS to me.

On test pipes can't you run an o2 sensor spacer to trick the emissions test?

[KurtCav337]

there's a way to cover up pretty much everything. I have no experience with that specific mod though.

Yes, but inspectors are "supposed to make sure" the cat is there...
