    Which O/R pipe with flowmasters?

    Looking into getting either a O/R h or x pipe and wanted to know which sounds best with flowmaster mufflers.

    DO NOT BUY BBK OFF ROAD X PIPE WITH FLOWMASTERS!!!!
    I made that mistake, it sounded like crap. The combo of 40 series
    muffers and the wierd X design don't work well together.
    It crackled and popped on decel REALLY bad.
    I added 2 hi flow cats and it sounded great. The UPR and similar designs
    sound great without cats, with flowmasters.

    X1000. I have a BBK H paired with original 40's and it sounds amazing. I find the Prochamber has a nice tone as well but way too quiet for an offroad pipe.

    BBK H with chambered mufflers. With 2 chamber Flows, it sounds like an old-school musclecar.

    General rule of thumb for me. With a chambered muffler the h always sounds better. With a straight through muffler the x will sound better. Hope this helps!

    The only problem is that I don't know if I have two chamber or straight through mufflers. I bought the car already with flowmaster mufflers installed and I have no idea what kind or series or anything

    Look at the muffler case and see what the muffler looks like im pretty sure they're gonna be your generic flowmaster 40s. If youre lucky youll have super 44s (better sound IMO)

    Get a mac h pipe or a bbk h pipe.

    Then enjoy classic sound.

    I have a UPR O/R X and Flows and my car crackles and pops pretty hard. I dont mind it.

    The drone at 70mph with 4.10's is something different altogether though. Ha.

    Okay, this is my last question. Would the bbk O/R h pipe for the 96-96 mustang gt (from american muscle) also fit the cobra, or should I get one specific for the 4V?
