Nope. Don't realize what he is talking about. It's probably because I wasnt even responding to his post.

That wouldn't surprise me at all, i'm thinking about welding in hi flow secondaries, unsure of whether to try fitting them into the Berk Midpipes or a single HFC prior to the muffler.

Sorry OP, but its on topic, I have carless dps and Vanguard catback which removes the secondary cats. Should I weld the secondary cats in? I do not mind the smell, it smells good actually lol.
