Magnaflow performance loss

[SP543]

can i do a tune myself or must i go to a shop and have them do it? any websites or anything with instructions?

 

[alacran]

how does it sound? is it really that slugish or just a few ponys? i was looking into a magnaflow rite now.

it sounds good, resonates inside a bit around 1500-2000 rpm but not horrible. I think i should have gone with a single outlet over the dual outlet so the backpressure would be closer to stock

 

[alacran]

so it would be a single 3inch in and 3inch out? i hopin for a nice deep mellow tone

I needed an adapter for the inlet to fit, stock piping on the inlet is 2.75". The stock outlet is a dual outlet design, so I bought a dual outlet magnaflow so it would weld in with no issues

Will doing this bring it back to normal or even better than normal?

I've had a Magnaflow muffer on mine for about 3 months now and love the way it sounds, no loss of power or anything. Only thing is that it's a lil much on the highway cruising at certain RPM's. The dron is a bit much so I've been thinking about swapping it out with the Flowmaster 530513 which is supposed to be more quiet on the inside.

Would you have any interest in selling the magnaflow muffler when it comes off your truck? Where are you located...

^+1 on what magnaflow you have cody? I assuming the muffler that the OP and the inlet/outlet setup is different is he doesnt have a 6.0 also..

I belive I have a Magnaflow part #12595 So I have Dual 3" in and a single 3.5" out. Yeah I'd be willing to part with it if I decide to swap it out for a Flowmaster.

Go with a dynomax VT if you sell the magnaflow Cody. I love mine and had issues with the flowmasters in a single 3" in/out configuration, kept blowing out cold rolled welds in the muffler's inlet. Dynomax is quiet until you stand on it, then it sounds better than the magnaflow or flowmaster I had installed prior.
