I got a question for anyone with an Apexi exhaust/muffler. Which one is the one that comes in different colors? I believe that it has 2 1/2" inlet. If you have it ... how does it sound? I was thinking about buying that particular muffler and getting a custom 2 1/2" cat back piping made for it (mandrel bent of course).

The N1 comes in different colors. Can't help you on the sound part.

Yea, that's right...the N1 universal mufflers are the ones that come in different colors. They are a lot louder than most universal mufflers but do sound good. I have the Dunk universal muffler, and I have to say that I have no complaints. All A'pexi universal mufflers either come in 60mm or 80mm inlet sizes. If you don't want to pay the A'pexi price, like the A'pexi style, but don't really care about the name brand, then there are many generic companies who make the N1 style.
