I'm looking at buying a 911 muffler (Dansk) for my six conversion but just curious if the outlet is in the same spot as a stock '73 rear valence. I want to be able to utilize my stock rear valence without modification. If not I might just buy one that has dual outlets like the GT style.

Also, is there any benefit to using a dual outlet versus a single outlet? Would the single outlet be restrictive? My engine is a 3.0, J&E pistons, webcam GE60 and PMO carbs.

The bad ass 3.6 and 3.8 would require it but anything less really doesn't though people think in their minds they do .. Think back to the days of American muscle cars just because a person would go to an open airfilter element didn't mean it went faster it just got louder..

Think about a 3.2 in a 911. The stock exhaust seems less then impressive.. To change to a ssi or something similar improves throttle response but not much else. You will see torque improve a touch.. But most cases they still run a 2in 1out becuase there is nothing to gain with dual outlet but noise..

Keep in mind I am not just speculating as I sold thousands of mufflers with real data points when I owned m&k.

Interesting. I have a M&K 2in / 2 out. The standard version where you can plug up one side and make it a single out. It felt like it gained hp when I un-capped the second port, but your saying its all in my mind? I'm running a carbed/cammed 3.2, about ~280hp at the crank.

You have a really hot engine. 280 is a lot for a 3.2. I bet your car rips.
