Default Agency Power - 2nd Muffler By Pass
Has anybody installed the 2nd muffler by pass (leaving the OEM center muffler)? http://www.suncoastparts.com/product/AP991172.html

I'm assuming you wont see much in power increases but lose some weight. Curious as to the sound improvements with and without PSE on, if any. Thanks!

To add, I'm considering these for my 911 GTS MT with a Cobb stage 1 tune..

The car in dyno video looks like it has non PSE exhaust. Not sure how the PSE on the GTS would work with the pipes.
