Jay, as J.Fro says, the design helps to quell the drone you so loved in your GHL and Mille Miglia.

Drone, Drone, Drone! I know. This has got to be terrible for perfomance. The engine is fighting itself to move the exhaust gasses out. The Crios mod will give some rumble at idle and low rmps but after that the flow will just over take itself and run its natural coarse. I think PSE may be the way to go. PSE routes exhaust directly out the tips from the motor with no BS in the way.

Interestingly enough, however, Porsche doesn't claim ANY hp increase in their PSE exhausts. Also, Jake has been saying most aftermarket flow thru exhausts don't provide any power gains over the stock system. Maybe the car needs some backpressure to make its optimal power?

Compare it to a gt3, or just a 996 stock exhaust. There more flow through and def. make more power. The exhaust for my motor was never slammed into each other forcing it back to the motor Just saying I think I have some more power to gain with a more open exhaust. I just hate drone....

I don't think it's as restrictive as it may appear. They may initially point at each other, but there are gaps in addition to all the perferations and holes that allow gas flow. The 996/GT3 cars would have to have different exhaust in any event due to engine placement. I do think the PSE or Pse ( Pedro ) mod. are the best options.

I have a 996 engine.. 3.4ltr. That is why I am messing with this topic.

Understood, but it's installed in a Boxter correct? The chassis dictates the exhaust as much as the engine.
