^^ Turbo Diesel is a whole other kettle of fish...
Turbo Petrol youre running afrs of 10:1 at Max power, Turbo DI Diesel make that 18:1 to be extra clean burning... That's 80% more air in and out at the same RPMs... When you consider you're doing that at 4000rpm, you need massive pipes to get the air in and out at lower velocities without restriction...
Precisely why a 90hp diesel has a better flowing exhaust system than a 167hp petrol...
