Nice write up! I also agree with you that the 14 inch is about a 7 or 8 as far as loudness goes. I've had the 14 inch on for about 2 months now and its gotten a little louder, but IMO its perfect. I've got the dual out exhaust with 3.92's and the only time I hear any drone is when going up a slight hill with MDS. I'm definitely glad I went with the 14 and not the 18.

 

Video is great for comparison value for sure. Lotsa time and gas, but appreciated by all in here.

 

The size comparisons really aren't the same between the single and dual outs. The 14" single is probably on par with the 18" dual. Also remember sound is loudest when you are inline with the tailpipe. In the case of the single side out, this points the sound as far away from the driver as possible, so it sounds quieter than it really is.

 

Thanks. I put a lot of time and effort making the video and comments like this make it all worth it.
