Interesting science JoeDoh

I always like to look at what the GM and Ford Engineers end up with. Both Companies have millions of dollars in R&D budgets to figure this stuff out. No Aftermarket company comes close to what the OEM Engineers can achieve. Take the New Mustang or New Corvette- Both sound Awesome! Stealthy at IDLE. Stomp it and they sing all the right notes. How did they route their exaust? What materials did they use? They are required to do this with Cats and still make it happen!!!

No Drone going on with these.

So I guess based everyone's experience here:

:If you end your exhaust under the vehicle- Expect to have some level of drone.
