Exhaust questions
All I have is an Eisenmann Axleback on my vehicle right now. I'd love to buy down pipies and possibly some mids too. But my dilemma is what are my diameters that I'm working(stock ones) with from the down pipes to my axle back? I just want down pipes and mids that'll flow right with my axle back. I plan on Buying a COBB soon, but just using the stage 1 part nothing more. So, I dont need a big huge diameter downpipes and mids.

N55 doesn't really need mids. N54 users often swap their mids to N55 mids for higher flow. Downpipes are usually 3" or 3.5" on N55, with some larger catted variants. Not sure for N54 since they are 2 pipes instead of one.

Thanks for the input...Still doing my research on my end. If I did just down pipes and left the mids alone wouldn't I be killing the flow?

The cats on the N54 mids will definitely hamper flow a little. You could always cut the cats out and replace them with resonators, or aftermarket mids are always a good option. I'd think about what axleback you are using if going fully catless though.
