    LT's and a catted Y. I wouldn't suggest the ORY unless you plan on using one of the restrictive plates or plan on getting a cam. It can really get loud since its almost like a cutout.

    None.
    GMMG IS an expensive catback like Borla.



    I still stand by Magnaflow. Same gains as any other catback. And to me....Magnaflow has a much cleaner, tame sound to it.

    Oh no here we go again about the loudmouth LOL. Some love it while others hate it. I loved mine b4 LTs then I started hating the drone, and the dumptruck raspy sound.

    Not to jack the thread I'm going to vote borla. A bit pricey though

    I have a Borla and LT pacesetters... I'm also thinking about nick naming my car the "Neck Bender" because everyone always looks my direction when I pass by.
    I love the sound of Borla

    I have put FlowMasters in all my trucks and a couple of cars that I've had..will never even think about trying anything else....by far for me the best sounding mufflers and performance bar none! Especially for GM vehicles!

    Sadly...flowmaster has a terrible reputation with the F-Body crowd.
    Their cat-back is one of the worst flowing systems available for our cars.

    First off I mean no disrespect with what I say.....I have to disagree with ya there....not sure how ya came up with that...If you can prove it to me I will believe ya but I have no problems with mine for my F-Body or my silverado2500 or my Ram1500..so your gonna have a hard time convincing me! "Their cat-back is one of the worst flowing systems available for our cars" In essence what your saying is it would work better for say a mustang than an F-Body camaro? So I guess I'm an exception to the F-Body crowd....

    I am obviously not going to be able to change your mind.....
    But the proof is in the pudding.
    You shouldn't have a problem with any catback though. Most go with what they like for sound...so by all means, if you like flowmaster...stick with it.

    The flowchart says it all. They really don't flow as well as others. I've previously used my butt-dyno to assume they don't flow very well, now I can confirm it.

    What needs to be specified here is what series muffler for Flowmaster... The 80 series crossflow has been the one that is dogged for F-bods.

    On the other hand the Super 40's have been Praised!
