thanks for all your help, i'm still confused about this because of all the options but i'll have to look at my car when i get home and see. But does anybody have a corksport cat back with any other exhaust mods? I wonder if it would still be street legal being as loud as it would be with a header, high flow cat.

I use a custom made presilencer (no it's not a muffler) similar to the RB unit. I borrow a buddies high flow CAT to pass e-test when necessary.

If anything the CAT is a smidge quieter than the silencer.
