You just need to make sure the hump in tailpipe sits correctly over the rear end. Not a lot of room for error with that part of the exhaust. It’s got to sit where it needs to sit.
I would get tailpipes correct, then measure the room between that and your h-pipe. Then, like Mike said, you can probably adjust the flow tubes to fit the muffler/flow tube combo.
