1 vs 2 muffler exhaust design

I recognize that photo; I shot it! Actually, our 3 inch True Dual Exhaust is designed specifically for the twin turbo charged VQ35/37 engine to achieve the greatest exhaust velocity for better mid-range boost response and high-RPM power. With turbo cars, the straightest exhaust path is the best way to allow the turbos to run at their maximum efficiency, which over course, helps the car produce more peak power. For N/A applications, the 3 inch turbo exhaust works well with supporting modifications(i.e. High Flow Cats/Test Pipes, ECU Flash/Tuning), however it does tend to shift the powerband to higher RPMs. We are in the process of developing a 2.5 inch true dual exhaust for the 370Z, and it will be very similar to our current 350Z 2.5 inch exhaust, shown here:




And hey OP, there is no such thing a stupid question! Ask away!

Great looking exhaust, I have a question though. I come from a muscle car background, particularly Mustangs and the difference between having a dual exhaust with a crossover vs without one is significant. You even find differences between different types of crossovers.

It doesnt look like you have a crossover in your system. Any particular reason why? Does this V6 engine family not react the same as a V8 engine with their exhaust pulses?

I think he mentioned this earlier but. The system in the pic is designed for a turbo application. V6 should still have some type of X-over in both NA and supercharged apps. In a turbo app. 0 back pressure is the goal thusly no x-over is really necessary.
