Denali Flowmaster Exhaust

[emufume]

Hi all, I am replacing my 40 series Flowmaster on a 2010 Sierra Denali, 6.2L this weekend. I am between a 50 series and 70 series Flowmaster. Does anyone have experience with these on a 6.2 vortec?

I don't care for LOUD exhaust, I just am looking for deep and mellow, with virtually no interior resonance (I'm getting rid of the 40 for this reason ).

Thanks! Your recommendations are very much appreciated.

on my 98 5.7 i but a bigblock 70 series on it i just replaced the muffler used the stock pipe out the back never had any drone
I Hate Exhaust Drone
last weekend i put a super 50 series ( 3 inch inlet outlet)on my 2011 5.3 i ran the exhaust out the side in front of the rear tire there is no drone
i still have to make adjustments ( hanger location on pipe, rotation of pipe at band clamp) there is a vibration when in v4 mode, its weird

flowmaster web site big block 70 series is there quietest
so far i like the super 50

i can hear the exhaust while getting up to speed
once your up to speed there is no noise
i like it
when you get on it (the g pedal) everyone around knows it
i haven't had a vehical this loud since the 80's
