    For the rest of the exhaust, is it Corsa cat-back or nothing? Since you decided to spend your allocated funds on headers and tune, which I would've done, you could have the whole package for just a couple hundred more (less if you weld it in yourself) if you went with a more affordable muffler. Unless the Corsa cat-back is a different size of pipe or if you want that brand for bragging rights, I don't see any benefit in replacing the stock piping and there are plenty of cheaper muffler options that give a quiet but noticeable sound with no drone. You could get one of the Magnaflows that are always mentioned here and whatever dual exit tip you want and have it welded to the stock piping. The Magnaflow 12589 is the most comparable to the stock sound. There are copies made by AP Exhaust that are virtually identical but without the Magnaflow logo stamped in the case for about half the cost. I got AP's copy of the Magnaflow 12259, which is one step more aggressive than the Magnaflow 12589 (18"L by 8"W body versus 22"L by 11"W body) on sale on Amazon for $31. No drone when cruising and has a deep but mellow tone when accelerating. Next to a retaining wall or under an overpass with the passenger side windows down, it sounds pretty wild at WOT. I think it's the best of both worlds and at a bargain price. I understand that there are good and not-so-good qualities of exhaust system materials and builds. But, it's just hot gasses- it doesn't care what name is stamped on the pipe it's going through. The stock exhaust is perfectly adequate in size and quality for you at this level and a packed fiberglass muffler is pretty hard to screw up, popular brand name or not.

    It would pretty much be Corsa or nothing but it certainly isn’t for bragging rights. I don’t do anything to impress other people. I like the sound of Corsa, no drone, and I love the angled twin side exit tip. I’ve never liked the sound of Magnaflow on any LS engine (I did like it on the I6 Trailblazer I had). I like Borla’s sound but they’re usually a bit droney. I’ve also like Billy Boat on Corvettes but the drone was pretty terrible on those. That being said, I’m hoping the stock catback sounds fine and I can just leave it.

    Sounds good. I'm looking forward to seeing the ARH LTs. I was leaning in the Speed Engineering direction for a long time but after some thought and quite a few reviews, I'm looking elsewhere.
    Are you doing the work yourself?

    Another small cat option is Magnaflow spun metallic cats. You can cut them down and modify them to your liking. I bought a 59956 2.5" in/out cat and turned it down to be a 3" in/out. Made it super short to fit in tight spaces. Just a thought.

    I've heard the same about Kooks.
    What model LTs did you get from ARH?
