Perhaps you could consider buying a 3" turbo back dump and having a local exhaust shop do the rest or just have the whole thing custom. Some local shops are quite competitive.
Im after a cat back system / turbo back system as i already have the custom dump pipe. Im finding the NON DPF systems hard to come across for the non DPF D40's
I dont mind having to buy a turbo back system if i have to. But isnt there a difference between NON DPF and WITH DPF systems? Or are the only differences the dump pipes????
