Magnaflow Exhaust

[WindyCityPilot]

I'm thinking of getting a Magnaflow muffler welded in to my stock exhaust. I want it to have a nice healthy sound outside but remain fairly quiet on the inside. Any idea which Magnaflow muffler would accomplish this? I've read that a larger, longer muffler will help reduce the interior drone. Any truth to this?

 

Something like this:

Also how well do mufflers welded in hold up to salt and winters? My stock exhaust is stainless steel on my '06 Silvy and the muffler I have welded in will also be stainless. My main concern is do the welds hold up or will those rust out in a year or two of Chicago winters?

 

Thanks for everyone's input!

That is virtually the same muffler I have, but mine is single in, dual out. I have the anodized version, not the stainless and it has been on there for several years. The welds have surface rust, but are holding very well. The shell of the muffler is just starting to show a few small surface rust spots.

 

I am about 2 hours south of downtown, so I know what you mean about salt in this area. Your muffler should last a very long time and I don't have any cab drone at all either. It is a fairly quiet muffler outside too. Louder than stock, but quieter than most. My truck sounds more like a Corvette than a truck wth loud pipes and it is pretty quiet inside too. You know it is there, but it is very comfortable at higher speeds.

 

I really like it.

At least twice a month I go to the carwash and spray the salt off of the exhaust, frame, axles, etc. All the stuff under the truck that people typically neglect. And I've never had any rust problems. Just remember...take care of it and it'll take care of you.

 

Yeah, the longer the Magnaflow, the quieter it'll be. But you will never totally eliminate the drone. I bought a Flowmaster specifically made to cut drone, and it still drones some inside the cab. That's a sacrifice you make to have a "performance" muffler.

I also go and spray the salt off the underside of my truck on a regular basis. So where does everyone get their mufflers welded on? Are the chain places like Midas and Meineke competant enough to do the job with decent welds or should I seek someplace else to do the work?

I bought the 50 series delta flowmaster for my 1500 and it still droned like mad... even though it was supposed to be the 'quite' muffler.

I had mine installed bya shop. I bought the muffler, they made the pipes and I saved about $100 over the system off the shelf.

 

That being said, this guy had a lift and could not weld worth a crap. Needless to say, I took it home, laid on my back and welded it properly on the creeper.

Here my magnaflow. Its not in the cab. Its not to overpowering. I have had it since last xmas. It has held up well in the salty midwest (indiana). The muffler is #15489

I have the single in/dual out in stainless. I believe its part no. 12278. It hasn't been on there long and I live down here in TX so I can't comment on how long it lasts. I can comment on how it sounds though. It sounds just plain nasty awesome. It was kinda quiet when I first put it on, but it really woke up after a few hundred miles of driving. Its plenty loud enough outside to be noticed and inside isn't too bad, but I do have a slight drone cruising at 60mph. However, it really isn't that loud of drone, just enough to know you got some pipes on your truck. I've heard quite a few exhausts on these trucks from Flowmaster, to Dynomax, to even glasspacks. Nothing IMO, sounds as smooth and nice as my Magnaflow does. I bought the muffler from a local shop and they custom fabbed everything else with dual 3" stainless tips for about $400. They did a great job too.
