Hi,

I'm not sure I can disclose the pipe diameter yet.

Drone is not bad. You can hear the exhaust while cruising, but it's not bad. It's definitely louder than stock in the car. Borla wanted to make sure it didn't fall in the "why bother" category by not making it loud enough. Everyone at the 805 meet (as in area code 805) liked the sound and the looks of the tips.

It hasn't been dynoed yet, but my butt dyno tells me the aFe filter and Borla exhaust make the car quicker.

I'm sure I'll have more info for you after SEMA.

Bob
