Since we are on the topic , what is the best setup I can make on the rest of the exhaust?
I only have bought the manifolds from the M3 that wont fit the 25/28i exhaust.
Read a lot on the internet and searched for full exhaust system for the m3 from supersprint and some of them have a X-pipe others dont.
Any one with experience on what is best?
Here in my country its probably cheaper to make a full stainless steel exhaust hand made then to buy a M3 full exhaust system , so since Im going to make it I can do what is best for power and sound
