Wondering about the OBD1 vs. OBD2 midpipes on an S52 with ebay headers.
Appears that mounting the OBD1 is more straight forward - no double wall pipes where they meet the headers and the factory location for the o2 sensor can be utilized. Downside is the single pipe merge at the o2 sensor that could potentially cost a few hp, though without dyno testing I'm not convinced this is fact.
Based on a search I believe the OBD1 midpipe mounts up nicely - anyone mate the OBD2 the these headers? Were you able to use the supplied clamp sleeves with the double wall pipes. Also, what O2 location did you use?
