Certainly nobody could complain about a lack of parts interchangeability with the 240. One area that Volvo did flip flop back and forth was the was the spin and solid flanges on the downpipe and converter. I changed out my brother in laws spin type converter yesterday and actually perfered it over the solid type. If I ever had to replace both the downpipe and converter think I would go with this style. Just curious to what others perfer and think the reason for Volvo having both styles.
