redoing my exhaust tomorrow.
on a scale of 1 - 10 how loud is a 50 series? 40 series?

 

i think the 50s arent that loud but the 40s and 44s are

 

depends on what you classify as loud...

my FM40 is the perfect tone for me. noticeable in the city, quiet (or at least it is cause the tires overpower the exhaust tone) on the highway.

 

2x that...i got a flowmaster super44 and there great cause you notice them when your drivin around but on the highway there pretty quiet

 

i like my flowmaster super 44. not too terribly loud, sounds good.

 

I have a 40 Series, when in idle it sounds sweet, when you dog it, it sounds awesome. When you first start your engine it drones, but once the engine heats up it quiets down and sounds awesome!

 

x2, I have a flowmaster super 44 and love it. I was worried about it being loud at highway speeds but to my surprise its very quite, a nice mellow tone. But when driving around town it has that really throaty sound that I love.

 

i have a 40 series and it sounds awsome i love it

 

My 40 is wicked loud but my exhaust stops at muffler. My girls 40 sound good with rear exit. But she has stock piping so its quieter.
