Exhaust question

[redheadstepkid79]

I've got an fmf full exhaust and the slip on looks like a supertrap muffler. I'm wondering if anyone is familiar. With this model and can I take discs out of it to make it sound different(like a supertrapp)? Thanks.

It sounds like you have an old FMF Megamax tunable exhuast. Yes it works just like a Supertrapp, you can remove discs to create more back pressure which is supposed to create more low end response and quiet the muffler a bit. If you add discs, it will decrease back pressure, making it louder and giving the machine better top end performance. You can still get replacement discs for that muffler if you feel you want to add more. Keep in mind, if you change the number of discs, you may have to re-jet depending on how much you chance it.
