catted DP? Either way itll be pretty loud but I would keep a cat IMO. A muffler too personally, just get a high flow one. I am running high flow magnaflow mufflers with resonator delete in my infiniti and it sounds good. I would assume a dynomax vt muffler, if they have the right size, would have no problem- idk what the stock muffler size is, or what kind of muffler that is so sorry I can't be of much help. But update us!
Keeping the stock downpipe for now so it'll still have one cat, removing the rest for 2.5" piping, the dynomax vt has a valve in it that opens under throttle to be louder but quiets down on idle and cruising
Thought I'd put up an update, got the 2.5" piping and tip put on Monday, a lot louder than I thought it would be, so I think I might put the stock cat back on to quiet it back down some, I will say it doesn't sound bad, it's very deep, just worried about getting pulled over for it since my tint is also illegal
I straight piped my cruze from the 2nd cat back and threw a Borla S-Type Muffler in place of the resonator. It's not too loud, a little drone inside at like 80 mph. Definitely a deep, smooth tone though. 2.5 inch trubendz.
I'll try to post pictures of underneath on Sunday or Monday when I'm off work, also going through my muffler options since I need to use a bullet style underneath because my tip takes up the whole length in the back, I went for the longer 3.5" truck tip to try and add a deeper tone and so I can't see the exhaust pipe from the side
