Thanks for the explanation.

May explain why Car Bone opted to not crossover their muffler flow...

There are SO MANY muffler options nowadays, including valved / active configurations. It's an embarrassment of riches. Oh how I'd love to dyno them all back to back to back to...

For street use where sound quality & quantity is likely to be far more important than the last few hp the best muffler I've ever had is the Fabspeed RSR, no highs, quite enough to hear the cooling fan, nice basso burble everywhere, no resonance.

I haven't dynoed mine yet but the car is far livelier, not really an apple to apple comparison as I also resealed the engine.
