Megan Racing Header 2.5 -> Carsound Cat 2.5 -> Kteller MidPipe 2.5 -> Apexi N1 Universal Muffler....

How would that cause a bottleneck? They are all 2.5inches. Is the universal muffler a genuine Apexi product? Or is it an Apexi N1 style?

real apexi of coarse...but isnt the piping 2.36 thus causing a bottleneck from

2.5 -> 2.36?!?

Yeah, Apexi uses a 60mm or 2.36. But no, you don't have to worry about a bottleneck. The difference in performance would be negligible.

whats the difference if it does have a bottleneck? lol...
