2G Apexi N1 catback exhaust fit the Megan Racing downpipe on GSX?

[98 GSX Auto]

Hey, I have a few questions about exhaust setups, I've searched but haven't found what I was looking for on threads on here.
I have a Megan Racing downpipe for my GSX and was wondering if the Apexi N1 catback fits up to it nice?
I have been debating on what I should do with exhaust setups also. I was also thinking about STM's 3" turbo back what are your guys opinion on them? Or should I stick with the Megan downpipe and Apexi catback/test pipe back.

The Megan downpipe and Apexi setup will work. I had one like that, but it had a shorter, maybe 6 inch, extra pipe bolted between them. I think it was to add length since the other pieces weren't long enough on their own. The flanges were the same size, so that's my only thought.
