I have a 2009 Dodge Ram 1500 with the 5.7. I am looking to upgrade my exhaust system. Currently I have a 3'' swept side exhaust. Which would be better a magnaflo stailess 3'' inlet to two 2.5 inch outlet swept side or a Gibson stainless 3'' inlet and 3'' outlet?
Correct exhaust system

I dont think 2.5" outlet compared to the 3" will make any "performance" difference, although it would be a tad more loud. If you can (and maybe you have) listen to Magnaflow and Gibson and see which sound suits you best. I am not as enamoured with Magnaflow as many are (although I have one on a 5.9 Durango) but its what suits your ears best
I have 18" glasspacks on my GMQ and to me its just "right"

SummitRacing.com has alot of choices and great prices. You can plug in your year and truck into the fields and narrow down your search to exhaust and it will show you what they have for sale for your exact model. I prefer chambered mufflers because they sound better (to me) and don't have packing to blow out (magnaflow) which will make it louder over time.

Be cautious of going to more than a 2.5" outlet if you run dual tail pipes. It seems to kill low end on the 5.7L. At least the 03-08 versions. Most exhaust mfg's claim the greatest power gains with a single tail pipe. I personally prefer dual exhaust/dual tail pipes however.
Have you considered the OEM dual setup for your truck? Sounds good and it isn't overly expensive. Of course it means getting the dual exhaust bumper but then you have a great finished off look as well.
Whatever you end up doing be aware that the 5.7L engines with MDS usually sound HORRIBLE with aftermarket exhaust as a rule. The louder the exhaust the worse it sounds( when MDS kicks in it sounds like a low flying helicopter ). I went with a Borla ProXS SI/DO and it is not too bad but you can still tell when MDS kicks in.
Also, the 5.7L HEMI motors are notorious for drone when the resonator(s) is removed. On my 04 5.7L Ram I used a Maganflow muffler and removed the factory resonator( SI/DO - exit behind each rear wheel )and within 15-20 minutes tops I would have a headache and be sick to my stomach from the drone. On the 08 with the Borla( exit under bumper )I don't get any drone to speak of. This muffler seems to do a good job, like Corsa, of combating drone. Magnaflow, Flowmaster, Aeroturbine, Thrush, Dynomax, etc... and even Gibson have a reputation for drone on the HEMI when the resonator(s) is removed.

I can't find it, but I recall reading something once about how if you have a V8, putting a dual exhaust will kill power, because of backpressure coming in pulses on them. And putting a dual will eliminate it. Or something like that.

My cousin has the exact same truck as me and he installed the Magnaflo dual 2.5'' outlet. To me it seems like he had lost bottom end performance, but I wasn't 100% sure. That's why I was questioning which set up to go with. I did install a single Gibson swept side a few months back BUT, everytime I accelerated hard it sounded or made a large hissing noise. So I went back to the stock set-up. Some people tell me that the Gibson muffler most likely wasn't welded on correctly (gaps in weld)and that created the hissing noise. Other than that I really liked the low end gains that I had with the Gibson but hated that hiss. I thought it was from it being chambered vs non chambered, What do you guys think? Thanks for the replies
FWIW, On my '95 F150 I simply cut the old muffler off and junked the whole tailpipe over the axle assembly. Installed a $25 Flowtech Raptor muffler and a short pipe out the side in front of the rear wheel. I absolutely love it. Sounds great and still hanging in there after 2-3 years. Not sure it is so simple with modern vehicles though.

Thank goodness he's not talking about using a Mopar original -- that thing would have rusted out and caught fire before the first turn of the key.
J/K NHHemi, but you gotta admit -- you invited that one. You know what I mean... EKP, UNH, '83.
