Thank you for your input. I'll look into the Borla ATAK. I think the biggest issue for me is that I'm so accustomed to the v8 sound and mostly associate the raspy v6 sound to the honda civics with the huge shopping cart wings, back in the early days of "fast and furious". I would be happy to find something that was quiet and deep sounding, but it doesn't sound like that exists. There's only so much you can do, so it makes sense. There's a video on youtube of a guy that just cut the mufflers off and it sounds like the more exotic sound of the Ford GT...that was interesting.
On a side note, what's the deal with the huge hp/tq differences of these tuners. For example, the Mountune package advertises ~40hp/80tq with exhaust, CAI, aftermarket intercooler, etc...but places like MPT, Five Star, and few others are advertising 100+hp with nothing but a tune. Being that it's a stock twin turbo with direct injection, that seems more reasonable...also closer to on-par with the diesel upgrades. Maybe they're just very conservative and the others are on the ragged edge of breaking?
