Hello,
Okay, I've already searched the forum for information about back pressure, but I didn't find what I was looking for. I'd like to know how the back pressure is affected in a TDI (90 hp) 1Z engine (manufactured in 8/94) if I replace the original catalytic converter with an aftermarket exhaust system (63 mm diameter). Or, what if I use an MSD replacement pipe and then an aftermarket ESD exhaust? Does this damage the engine? And what about the sound? Can you get a sound similar to a gasoline engine?
Best regards,
Carsten
P.S.: This weekend, there's a BERU TOP 10 event in Oschersleben.

I'll go there and ask the Alfa Diesel people what kind of system they have installed. And I'll listen to how it sounds. It's just a JTD, but the sound should be roughly the same.
