Rebuilt/improved OBX vs. PPE LTH
 

Just had this idea since I'll be doing a custom cat-back soon and the guy building it is a very good specialist. What are the main differences between OBX and PPE long tube headers and is this something that a good specialist can upgrade somehow to bring the quality of OBX closer to PPE? Quality of welds, materials used, design ...?

The difference is the collectors !

If your fab guy is legit he can chop off and add a better collector system !
