I traded it for a Smoothie Factory. I don't post much anymore....in fact have not even been on 6speed in a while because I am busy with the store. It was losing a lot of money when I took over, and I am trying to turn it around.

As a comparison:
...My bmw 328 is 100% stock and DB on my morning commute is 88 at 80 mph-very quiet - most of it tire noise- can't even hear the engine. On the 911 it is 90 db as of now..the only reason why it sounds "louder" on the 911 is because of drone. If our system works, it will only add 2 lbs of weight. and removal at anytime...and eliminate 95% of the drone. On the 2.5 tip section which will be hear next week. Hopefully reduce 2-4 db inside along with our new design after the x pipe, which will help with another 2-3 db and very little drone. Talk about the ultimate system : ) reversible in 5 minutes.

This exhaust on a Tip would not be recommended.
I agree. And I have made plenty of various ones to know... Even with 4 muffler and 2 cats and 3" tip it will be loud...

It seems that a 2.75" might be a better fit for most of the real world modified street cars?
Higher Velocity and less drone.
