NY Emissions, Highflow DP's, Exhaust and Tunes?

Hi All,

Thinking I'd like to go for a sound that's a little more refined and it would be nice to pass NYS Emissions anyways.

Anyone have experience running high flow cats? Any specific ones out there that will pass an emissions inspection? Do they eliminate waste gate rattle? Do they eliminate drone? Will I no longer get dirty looks from older folks when driving by?

Currently have Project Gamma catless pipes, full miesterschaft 102mm and DME S2. The car is mean but I live in the middle of nowhere and am tired of getting dirty looks from country club goers.

Tempted to go with a highflown cat and Bootmod. Bummed about losing the DME performance but I like the idea of being able to turn on and off coldstart along with changing different maps. If DME had these capabilities I'd never change.

Any advice appreciated, very unfamiliar with high flow cats.
