    Intake & Catback

    I has my EGR setup removed when I changed intakes so the EGR holes on the headers had to be capped. My new headers are a smooth race setup without any air or egr plugs just the o2 fitting.
    Fast is larger and flows more air but is more expensive. I have seen cars with over 500rwhp runnung ls6 intakes at one the shops I got to. Also I'm not a fan of the Borla, they have a distinct sound that i don't really care for personally. I didn't even know I would like my SLP power-flo since I have only heard LM1 and LM2 kits, but love it and it was $600 shipped. I have only seen 2 Camaro's and 1 Formula with Borla kits. Most people I know have Magnaflow or Corsa and I know 1 person with the GMMG chambered catback. It sounds great if you want loud.

    I'm not really looking for something like a SLP loudmouth. To me that is cheap and sounds annoying. I just want a deep, aggressive sound that is not overwhelming. I'm probably going to end up going with borla or corsa.

    Then go for the Chambered Exhaust by GMMG if you have the money.

    Otherwise, Magnaflow is about the best for the F-body.

    That's what I planned on doing too.

    Isn't it pointless to say that one catback is the "best"? Depends on what you're looking for I guess...

    Exhaust

    Mine is actually a LM2 race muffler with 2 polished power-flo mufflers(glasspacked), loud when you step on it quite when your cruising and no raspy sound since I have and ORY and headers. Also A great fit and finish, didn't need adjustment like some catbacks I have installed.

    My dilemma is finding the right combination to produce a fairly loud, deep, aggressive sound without rasp or a lot of popping. I don't like that.
