Well, I am not a great specialist in the domain of car exhausts actually. However, my brother owns a 8th gen. Well that car is tuned up as ****. I do not really know how he done it, but the car is having 541 horsepower right now. He has also changed the whole Exhaust Setup and the car is lound as ****. When i heard that it for the first time, i thought it was akrapovic or something like that. However, he has actually found a certain article about exhaust systems on
Atfulldrive. Basically it is the basic exhaust, it is modified.
