Saturday I went to the exhaust shop and had them ditch my dual/dual flowmaster 50 series dual side exit(in front of the tire) and I had them put on the biggest Magnaflow #12588 Stainless Muffler. I had it run dual 2.5 in/single 3" out behind the tire. I was looking for less resonance on the highway and cruising around and I got exactly that. I'd definetely reccomend it, I can see right through the muffler but I hear the tires on the road at 80 MPH and it growls nicely when I get on it with just a slight rumble cruising around town. Its a huge difference over the flowmaster, which sounded good at first but the sound quality has steadily declined and the resonance was really starting to get to me. Now I just need to figure out what tip to put on... I decided to wait on that because I couldn't figure out what to get.... any ideas are welcomed

Just realized this should be in Truck Performance... Would one of the mods mind fixing this...? thanks

 

Im hoping Ill get the same results 40 flow with no cats and lt's is definately cuasing me hearing damage

 

Go with the Corsa Dual Pro Series 4.0 it's a pretty hot lookin' tip.

Corsa Tips

Do you get any low speed resonance?

 

Yea they are sexy, but damn $170. I think I'm gona half *** turn down /side exit in front of pass. rear tire when mine gets here. I'm so impaitent I'm fixin to go get one of these flows laying around the house put on. I want my Magnaflow BAD.

 

 

I too installed a Magnaflow can on my truck. Basically an "axle-back," system. It's great to say the least. It's quiet, and is only loud at about 1900RPM and when you get on it.

 

I put a Magnaflow stainless tip with the rolled end. It really looked good when it was put on but now it is all stained and tarnished. I have tried metal polishes and steel wool but the stain won't come out. Don't know if I just got a bad one or what. I think I'll go chrome next time.

 

when just cruising at a low speed I don't get any resonance unless i accelerate, if so I do not notice it (still used to the flowmasters) I like the corsa tips alot but they are kinda pricey... May be worth it though

 

I had a '99 ecsb with the 5.3L and put a Magnaflow on it. At 1600 - 2300 rpm that thing was a drone monster, so I'm still kind of leary on the Mags. I know that the muffler was not stainless and it wasn't too long either. Now my new truck has the 6.0. I thought about the long stainless one that you have, but I hate shelling out $200 bucks for something that drives me nuts, especially if I'm towing for 200 miles.

Yes the Corsa tips are a little pricey, but not too many people have those. I've got the dual 4.0' tip, now I need some sound to go with the look, I'm leaning to the FloPro 2503.
