What is the QUIETEST Exhaust/Downpipe Combination?

[BlueBomber]

Hey all,

So here's my dilemma.

I want to enhance performance with a better flowing exhaust and downpipe. What exhaust and downpipe combination is the quietest possible or closest to stock sound levels?

What's the best option for this purpose?

I am thinking a catted downpipe and a resonated exhaust of some sort, but am not sure what type yet.

Other than Milltek, Levels and a few overseas companies, are there much options for downpipes?

What diameter? Seems all the 2.5 exhausts including Magnaflow are pretty quiet.

FSwerks is pretty quiet. Their video is with a catted COBB dp, and its not loud by any stretch of the imagination

Sooooo...how did they get a COBB DP? I feel like they're holding out bigtime. It's like dangling a carrot in front of a horse.

Good question...how did they get a Cobb downpipe? Or why?

I'm sure they are in cahoots with each other. "you scratch our back we'll.scratch yours"
Plus I'm.fairly certain cobb just recently got their own R&D fiesta
