100% correct...!!!!!!!!!

 

The guy at Meineke that installed my "slowmaster" said it wasn't actual stainless, but aluminized. I don't really see a manufacturer spending the money on a base line truck to install stainless exhaust, would just drive the cost up.

 

Don't think I've ever seen an aluminized flowmaster, they are usually heavy guage steel. I ran a 50 on my jeep for a while until the noise drove me nuts, went back to the stock muffler and the noise was down and the power was up. Only advantage to a flowmaster is that they are like haveing a skidplate on your muffler - awful hard to dent one

 

I never write on these things, but after reading this post and being a professional fabricator and engine builder I felt obligated to. Every flowmaster muffler is aluminized unless it is stainless steel, which many of them are now. Also, a 50 series muffler is a far cry from a big performer. They use them because they are quitter and abide by the laws better. I have a 2012 ram express hemi and with just a single 3" in and dual 2.5" outlets, all stainless just like the factory pipes, I gained 7hp 4600RPM and thats with factory resonators still on. I'm not sure if any of you guys are professionals and I'm not talking about some high school shop class, but I have never seen a flowmaster last less than 5 years. Many last longer than the vehicles they are on. I have also used the all might magna flow on my 490 RWH dakota rt and it rotted off in under 4 years. No matter what you go with they are similar, o and $200 is a bit of a rip off but I can easily see the charges. The new cherry bomb line is suppose to make more power, but I haven't gotten to try them out yet.

 

O and my muffler on the ram is a 40 series 16-gauge 409s stainless steel flowmaster p/n: 80430402. Sorry I forgot to write it down. I had a true dual 3" setup on my dakota with super 44's and it sounded like a race car. The application definitively dictates which muffler to go with. The most discussing thing I think I see with these rams are those DOD mufflex magnaflow kits what a rip off at $250 for a $69 muffler and two extension pipes. My muffler was $69 and my stainless extension was $20. Took me under 45 min in driveway on my back didn't even need to put it on the lift.

 

Well had my old laptop's HDD not crashed I could have shown you one where the top basically looked like a slice of swiss cheese in less than three. Also, if you go do a search in the 3rd Gen Ram section, you'll find a few dozen posts saying similar...

 

I assumed, perhaps incorrectly, since I have had the truck 3 years now, and no rust just some. heat tarnish, that it was stainless. Thanks for clearing that up.

 

to go back to the stainless comment, many times the factory and cheaper aftermarket "stainless steel" exhaust are made out of a 400 series CRES (corrosion resistant steel) that will "rust" on the surface but it will not rot straight through anywhere as fast as the basic mild steel they used to use for exhaust before the oem's started upgrading. go buy some "walker" replacement exhaust and have fun replacing it every year if you live in the northern climates.

300 series generally has a lot more nickel in it and will surface shine to look real pretty and will resist that surface corrosion much better.

I can tell you that i can make any metal look like swiss cheese in very short order with a salt water solution and heat.

i recall on a 94 dodge we owned that the exhaust held up for quite a while until the inards of the muffler actually started breaking apart and vibrating, presumably from internal corrosion. this was about 10 years down the road with 120k or so on it. i think that truck may have been when dodge started advertising their "stainless" exhaust, with the "new ram"

 

Can you remove the resinators from 2012 Ram without throwing any codes??

 

yes, i removed mine on my 2009 when i put a direct muffler swap on my truck before i purchased my maggy cat-back exhaust
