    Do more mods increase the need for a CBE?

    I know that just getting a full TBE does little for these cars or my model ('12), BUT if I have many other mods such as the TMIC, DP, FP,3 port, CAI, does the amount of power a CBE will produce increase? Anyone ever done this mod as one of their last ones? What if ELH are also added before a CBE?

    Yes.. the more power you're making the more of a restriction the CBE will be. At stock your gains will be nill, at 500whp you're looking at 20whp or more difference.

    Ahhh ok, well with my current mods and then adding ELH, tumbler and injectors I don't think i'd be pushing more than what? 330 whp? I don't know how much the CBE would help at that point. Really don't want to spend the added money on it tbh.

    Meh, I'd hold off then until you want to =). Not hurting much in the mean time.

    I think KillerB was looking to do some dyno experimentation with their new catback in development vs a few others. They were pretty set on the fact that it makes a larger difference than most believe. I'll let you know if I see any updates on the matter - I wouldn't expect them anytime soon though.

    The newer dual-tip exhausts flow better than the previous exhausts. I believe there is LESS of a need for an uprated catback, but it can't hurt.

    I don't have a choice but to hold off, I can't afford any of those expensive CB's and most of them are quite expensive it seems. Oh well, i'm not to worried about it if it's not that much of a power difference.

    No need to press yourself financially for it. Look for used ones in the mean time - never know when you'll find a decent deal pop up.

    Yeah I know, the other thing is I don't really want much of a sound change... like not louder and have cops bugging me all the time.

    The quite cbe's arent going to be much better on horsepower and are the more expensive ones it would seem.
    If you dont want to spend the money, dont care about the extra <20Hp-ish that you gain, and dont want a sound change; then I would stick with stock.
