Now the 3 inch catback will do no good or better? Will at least adding XR1 borla mufflers sound better than the pfyc borla mufflers (assuming you have some idea of what they sound like :/) Not trying to sound v8 just trying to sound clean with a bit of volume and intimidation at a v6 level. Current setup sounds only slightly better than probably stock mustangs... idk
Want more flow.. Get rid of the plog/Dp and go with a set of headers. With your current setup there's no way your out flowing what you currently have.

The only mufflers from Borla that I've heard on the 3800 are the XS pro (that's what I ran stock and what I still run on my 3" setup). It's slightly louder but that's a giving going from the stock 2.25 to 3" exhaust but I'm also running a large 32" resonator that quiets it down. Only reason I went with 3" over 2.5" is because I got a hell of a deal on the piping and was way cheaper then what the 2.5 piping was selling for.
