while the rpm range in question is and can be used during normal driving , how often do any of us have our foot to the floor , if we did our rear tires wouldnt last but a few months
if you block/limit your gas pedal to say only open 30% , 50% , 75% and dyno it that way , youll see alot lower readings from the dyno , which is my point
granted we all build our cars for different reasons , but we all do it for the fun and enjoyment , and random fun out of the country , so hopefully you understand my point , i wasnt trying to rain on the parade

Nah - no raining on any parades. This was a healthy exchange.
"......Block/limit gas pedal to 30%, 50%, 75% ...?" You kidding me? No way Jose! :-).
If I'm going to pass someone - or get on the on ramp - it's going to be with some internal combustion enthusiasm! :-)

when you're that modded yeah its a restriction, but for a bolt ons cars the muffler isnt your choke point.
neat to see the difference, and your car looks healthy

I'm in the middle of my cam/head install. But I have the vortex 3" in and out mufflers and a 3" xpipe sitting here. You might beat me on installing of the exhaust. If you get them on. Please let me know how they sound. Thanks

No idea my brother.... I would "surmise" there is additional flow there -- but no way to validate on my side.
