do you think it is kind of stupid to tune without a cat delete? cause i dont want the car any louder, even hfcs plus xpipe can kinda add sound and drone, i know some dont but still....all i have is pulleys, envy intake, catback.
I was in the same boat - so I went with Turner Test Pipes, which just delete the primary cats but retain the rest of the factory OEM system. Basically sounds the same expect more aggressive under WOT.

Check out my review here -

The primary cat delete definitely makes a difference, but even the tune without the primary cat delete is worth it...
