I’m quite happy with my 4” MBRP. Drone not too bad.

Flowmaster 50 Diesel, I like it a lot.
No drone, sounds like a D7 under load.

4 inch magnaflow not too loud/not too quiet.no major drone.

X2. In addition, mine is now over 12 years old (304 stainless) and it is still in perfect shape.

Mines the cheaper 400 grade stainless. It’s on about 5 years I guess. Still looks good.

I ran an MBRP on my '05, and had no complaints.

I'm going to throw one our there... BD used to have heavy welded steel mufflers... even weld the flow direction arrow welded. And has great tone...

I dont know if they even make them any more.

My MBRP that came with my galvanized system has served me well for many years.

I'm returning to a stock muffler soon. I'll just move my EFI dial up a notch. I cherish quiet in my old age.
I've ran a Shuttleworth HD Diesel muffler from Canada for 12 years. Zero drone but it's coming out soon.

fte resonator!

I have MBRP on '96 no drone that I can hear!

The FTE works great If u have drone, that alone is a lil loud imo. But I like it!

 

[Presmyk]

i still want it to sound nice just not as loud lol

Maybe just me but I have not heard any six cylinder with a loud muffler sound good and that includes 4 cylinder fart mufflers. Of course my life involved V8 gas.

 

[elephantrider]

the fte is super quiet on my '19. ...but the '19 and on models are quiet anyway.

That’s a delicate balance.
