Ok sorry if this is a stupid ? but I know someone could answer this real quick probably. What is the difference between Buschur Racing's LANCER OZ HIGH FLOW CATALYTIC CONVERTER which is $150 and their LANCER OZ OFFROAD PIPE which is $50? In another thread I think Boe was saying that the RRM test pipe and the Buschur Racing Offroad pipe were almost the same(sorry if I put words in your mouth). Also the piping on my flowmaster exhaust is 2.25. Would this be a problem with the test pipes being 2.5 fitting wise? Thanks

 

Offroad pipe in RRM speak is test pipe. High flow cat is exactly that. As for piping disparity, it won't cause any problem. How else do you think they bolted your exhaust to your cat.

 

Lol yeah i told you that was a stupid ?. Yeah after u say that it makes total sense about fitting.
