Secondary Cat delete only?
Has anybody done just a secondary cat delete? I've seen a few videos with resonator deletes, but none with just a cat delete. I'm sure there won't be much HP gain if any, but what does it do the sound?

Fabspeed X-pipe. I would like to actually hear it under load, as revving in neutral is not always indicative of exhaust tone. |

i actually just got my car back from the exhaust shop today with a secondary cat delete and resonator delete with the stock cans on...sounds great! quiet during normal driving, but sporty when you get on it!

i'm running 3" tubing off the primary cats with an H-pipe on the center section. no sound clips right now, but i'll get some this weekend when it dries out a little. we've had heavy rain all week. it sounds great though, good bang for the buck.

You might as well replace everything. If a primary cat goes (it was common on the E46), you're looking at:

Because if at some point you plan to sell the car without spending some time making license plates....you are kinda going to need the original emission control system on it - no?

The no was directed at the strange comment about buying a new OEM system. I'm confused to why one might have to do this, and why it would have any impact on selling the car?
