I´m thinking.. for a start... trade the OEM exhaust system to a Ragazzon.
My doubt is with bigger diameter pipe and without any rear silencer.. will lose backpressure.. and be worse.. with it.
It would be interresting to have a before and after dyno test.
Now I will ask to my Alfa Dealer "Motor Village Lisbon" to check some parts to see if there is diference between 180hp and 210hp.
Like: Pistons, Head gasket, Cranks, Crankshaft, Head cilinder, Intercoolers, Turbo, Inlet manifold, injector... etc
eheheheheh not just "increase" debt in injector and "more" air... and be a "octopuss or cuttlefish" and spray some black smoke on the run.
Also with that system you still have your DPF which kills most of the sound and adds back pressure. So even if you don't have any rear silencer the car will still be quite as you also have a VNT turbo which also kills the sound.
Maybe we should consider removing the DPF with a pipe... better for the engine as well.
About the differences between the 180...210 will look deep into that one. already found some but need to look in the details
After some research I found that between the Diesel version 210hp and 180hp.
There is some difference. See Part-numbers
Turbo - 55278618 vs. 55279544
Intercooler - 50533819 vs. 50534301
Injectores - 55260836 (are the same in both cars)
Pistons - don´t have final info yet
Crank - 55277649 (are the same in both cars)
Crankshaft - 73503942 (are the same in both cars)
Headgasket - 55279536 (are the same in both cars)
Cilinder head - 73503854 vs. 71779388
Inlet manifold - 55281227 (are the same in both cars)
EGR - 55283264 (are the same in both cars)
