i did a search and didnt come up with much. i am looking at the corksport and the RB 3 1/8 inch downpipe. is there anything that would make the corksport DP work the extra 50 bucks? both are same size, and both Stainless Steel. just wondering before i buy one.

 

I think the difference is in what they bolt up to. The RB DP bolts up to the RB presilencer, while the corksport DP bolts up to the corksport midpipe.
