I must be getting old... my exhaust is too loud for my liking. Although it sounds pretty tuff - it's a very loud drone at idle, and too much of a cop magnet.

I run extractors, steel cat, muffler and 2" pipe, not too sure what I need to modify to lower the noise levels. What the cheapest way to sort it out vs the best way to sort it out?

add another muffler

As above or replace your existing muffler with a better/bigger/notsooldandshagged one.

Cheapest way would be a 1.75 flange gasket if it has any joiners in it. Muffler is obviously the better way with less flow restriction

Just replace with another milder, baffled, muffler... should be around $70 to $100 for a newie... or put a hot dog on the tail pipe, but that may cost more than you want to spend... bit of a shame to restrict it again, by making it quieter, but if you dont like the drone...

Edit : maybe you could adjust the idle to make the drone less than it is...

Throw in a resonator before the muff. That will cut down the drone/noise

This bloke on ebay has Redback hotdogs for a decent price, im running them on both my zooks.
I use a good quality triple pass with a single 9" hotdog in my tintop, much quieter than my softtop with a cheap single pass and twin 9" hotdogs.
A good triple pass muffler may do the job.

EDIT/ hotdogs may actually be 12"...

You can get basic hotdogs a few sizes. Smallest my local has is 2"x 6".
