You can get different grades of both Magnaflows and Flowmasters so when comparing make sure you're comparing two of the like "grades". I've had Flowmasters for years and just recently went with a Magnaflow for the first time on the wife's burb. I like the sound of both to be honest with you. My '77 has 2 40 series flowmasters on it (and I've had 40 series on 3 other trucks in the past) and just LOVE the rumble and tone that comes with it. With that said, be prepared to have "drone" throughout the cabin of the vehicle. Personally, I like that and it's just part of it but some people don't. You'll run into the same thing with a loud enough Magnaflow, though.

So 07 burb how are u liking the magna on the burb. Im looking into getting one but I dont want it loud. My job is 55 miles one way and I dont think I will like it very much. I just want it to sound a little better than stock

As of now I just have the magnaflow with the resonator still there. We just took it on a 1000 mile round trip and it was great. You could hear it when you got on it but was fairly quiet while cruising down the highway. Tonight I'm taking off the resonator and putting SLP tips in it's place. I expectit to sound even better :waytogo:

I have a 14 inch case length magnaflow muffler. dual in dual out. cant remember alll about it... personally i like my flowmaster so much better! like im in love with my flowmaster and i honestly think i will ever buy a magnaflow ever agian. My magnaflow had a really bad interior resonance. my flow doesnt have as bad. it was quite at idle but when you got on it or stood around 2000rpm it was loud as hell! Personally i think that it might be the same loudness as a single super 40. not true duals.

Thnx for the opinions guys it's helps on making a decision. I will probably stick with flows and go with 40 series. But should I go with true duals or stay with a single muffler two in two out?

I have a dual in dual out 50 series on mine. i was going to do true duals... but i changed my mind and me and my dad are going to build a motor forthe yukon and then im going to build a 3 inch exhaust from the collectors of some longtube headers. prolly going to go with alittle louder 50 series delta flow muffler. its going to be a single out the side like stock position, with a 4 or 5 inch tip. hope it sounds mean!

I've had flowmaster dumped/turned down on my nbs and Magnaflow with resonator delete/tips on my nnbs.

Magnaflow FTW.
