Magnaflow Single Side Exhaust

[Green_Monster]

Installed the Magnaflow today. The sound is exactly what I was looking for....quiet when cruising and just loud enought when on the accelerator. After hearing the Magnaflow, I think the stock exhaust was droning, I just didn't realize it! Shifts a lot smoother going in to 2nd at WOT, and pulls better throught rpms. I have been driving the SCT for a while with stock exhaust and my "seat of the pants" says I gained some considerable power (for just adding a cat-back).

 

I don't have the best camera, just a sony cybershot, so the sound isn't great but you guys should get the basic sound. Enjoy!

It sounds like a truck should sound low and mean!!!!

 

which exhaust did you put on and if you don't mind was it expensive?? Was it just a muffler or a complete exhaust?

 

Thanks

That sounds awesome. Thanks!!! (Even though you just cost me some more $$$ since now I have to go get this).

 

I have been considerig Magnaflow, but haven't had a chance to really hear one yet, now I have. Should sound even better from a 6.0 Vmax.

The sound has gotten better over time. It's better than ever!

I have also gained mileage already! I was cruising back from the track at 70 and getting almost 20.5 mpg! I use to only get about 18 at 70.

That does sound preety good. I've been looking and looking and still cant decide which one yet.

Helped install a Magnaflow system,dual exit, on a buddy's 06 Z71 last year and it sound's awesome.Was'nt that impressed untill I heard him pulling into a parking lot a few week's ago and I had to look to see who's vehicle was sounding that good.

Sounds good - although save some $$$$$$ next time by swapping out the stock muffler and adding an exhaust tip - did that to mine for $200.00

I know this is going to sound crazy but...i was bored and unbolted my Y pipe form the rest of the exhaust and i was impressed with it..

Not very loud or anything. it was dumping right under the cab so it wasnt the greatest inside, but my question is what if i just removed the stock muffler all together and ran i straght pipe where the muffler was?

 

What do you think that wouldd sound like...

[eestubbs104]

Awesome sounding exhaust system you have there. I wish I knew how to put mine on here. All though, I sometime wish mine sounded that "soft" and sweet.

 

I had a custom system installed on my 2003 Silverado. It now sports a true dual exhaust system from the exhaust manifolds back. Yes, I have two catalytic converters, two Magnaflow race series mufflers and customed installed 3" Stainless steel pipes. Are they loud, let's just say that they turn heads when I excellarate hard.

new member and wanted to respond. I used the following Magnaflow parts:

 

muffler: #12279

tip: #35206

 

I have a NBS SC/SB and Magnaflow doesn't have a kit yet so I went cheap to experiment. I have had several Magnaflow systems on previous trucks.

 

When welding the muffler in I found out that the front of the stock exhaust is 3 inch and the tailpipe is 2.75. A muffler shop can cut a shim from a 3 inch pipe and it fits perfectly inside the muffler and the tip for installation

 

I ordered both parts off of ebay from Performance Curve. Make an offer and see what they come back with. I paid $75 for the muffler and $40 for the tip (free shipping) and $30 for the welding in at the muffler shop. Muffler fits perfectly between supports on my truck.

 

Nice sound just above stock, good mellow response when accelerating hard (which is every opportunity for me) and no drone but you can hear when the AFM kicks in. Still I am pleased with the mod. I'm so pleased that I might not order a full kit from Magnaflow.

 

I haven't taken any pics (I know I'm letting the board down, sorry).

Your truck sounds almost exactly like mine.

 

I really like my Magnaflow w/3" duals, but sometimes I wish it was a little bit louder.

 

One day I might purchase some bigger tips for more sound...

You mean GMC doesn't give them away Does the crew cab have a resonator after the muffler? If so you may want to get it removed to clean up the exhaust flow. Let me know how it sounds.
