Default Interesting Fact on Exhaust....

we have all seen the underbody shot of the PSE im sure...

but has anyone crawled underneath a non PSE "S" model yet?

today I did at the dealer and I noticed that the center exhaust still bypasses the side mufflers whilst the outside exhaust goes thru the side muffler.. (sort of like a partial gundo hack), i'm very curious to see the underside of a Base model as this really surprised me... the exhaust goes from the header to the center muffler, half goes out to side muffler and the other half goes thru the center mufflers..

did not get to drive the car to hear sound difference but this is a very different approach than the 997 where all the exhaust went through the side muffler unless you had PSE or a Hack on the vehicle.

if you look at this photo:



the sides are same without PSE but the middle muffler is all one piece, and the exhaust exits the same way... very curious to see how the Base model does it with only one exit.

fvd Brombacher is making an aftermarket muffler system for the 991 and this is what it looks like for the base model. They claim it saves 39 lbs. over stock.
