[MASS-HOE'Z71]

Can't say too much about the 40 series, I had 50 Series delta for a bit tho, around town it was fine and had a nice troaty rumble acceleraing then sounded sorta stock at cruising, highway driving tho made me hate it, drone cuts in around 1900-2000 rpm which is just about where it runs on the highway and took it off not long after, been looking at maybe the whole Gibson cat back tho with dual outs just wana make sure it fits my suspension, $70 sounds like a reasonable price tho, I think retail is like twice that

So is the conclusion the 40 series will piss me off on the highway? I go to college 3 hours away and 2 1/2 hours of it is the Mass TurnPike

i have a 50 series FM catback on my 05 yukon and i have zero drone on the higway. you can hear it a little bit but it`s in no way annoying.

I have no drone with my 50 series, just loud as **** when you stand on it.

I can vouch for that, heh. Max's setup sounds badass. I'll do something similar eventually.

Will a 50 series with stock exhaust give same results?

I would imagine that the tone would be somewhat different without the LTs, but it would still sound good.

Sasquatch is your catback system one from a shop or did you order the actual FM http://www.summitracing.com/parts/FLO-17419/

All droning aside, still no suggestions on sizing?
