IMO, Borla is second to none.... for a gasser. Diesel I doubt they have a grip on yet.

Hushpower is a packed muffler...
Hushpower
you would probably see "slight hp increases" if you just put a length of 5" pipe in a 4" system
Borla is just an expensive, high quality, packed muffler... There's nothing to "grip" when it comes to diesel exhaust vs. gasser exhaust
