B58 midpipe + downpipe?
Anyone pair a midpipe and catted downpipe on their b58 car?
I was looking at Dinan midpipe and waiting to see what catted downpipes are available...
Is there another midpipe that is cheaper and/or better fitment to variety of downpipes?
Any gains on dyno from a stage 1 tune, by adding downpipe and/or midpipe?
