The ATAKs are loud as hell and IMO don't even sound good with long tubes and no cats. There's a guy in town here with that setup and it's just all rasp. If you want something loud, I'd recommend the S-types with LTs/off-road setups. Honestly I think they're just about as loud as the ATAKs with that kind of setup, but have some sort of tone, not quite as raspy. Here's a clip of my car just idling....you can hear it a mile away when you get into it.
Thanks.....I had bought S types and didn't like the sound or think it was loud enough. I did just add cams so have to see what it sounds like now. I don't mind it being loud I like it. But I do want some sound that goes with it other than just loudness if that makes sense.
