This week end I had the opportunity record three different mufflers connected to 2.0 heat exchangers.
Stock - Scart Sport - Scart Super Sound
The big bumpered 914 is a 1.8 and had the cat removed and was converted to 1973-1974 2.0 heat exchangers
The green one is a stock 2.0
The last yellow one is a german 2.0 sold with no options at all... Not even retractable seat belts. The fist time I see that on a 2.0.
Enjoy
