out of the two, i like the Magnaflow.

I have magnaflos on Blumax - it sounds awesome. Ask the folks who attended Frenzy - got lots of compliments. Cat delete and a custom exhaust system. I had flowmasters on my Mustang and did not like how they resonated and vibrated the whole car in the mid rpm range. Switched those to magnaflos as well.

Magnaflow 100%

Also your headers. I hate to tell you but you tagged the wrong cylinders together.
You should have paired 1/4, 2/3, 5/8, and 6/7 for best exhaust scavenging.

They sound pretty good, but flow terribly. My truck went from 371whp to 436whp when I switched from a 2" exhaust with a flowmaster 40 to a 2.5" exhaust with magnaflows.

im going to do a full stainless set up this winter. im ditching the 40 and going with a resonator of some kind and a magna. but man does this 40 sound fantastic.

Dynamax VT for duel 2.5 quiet at low speeds / roars at higher/ no drone . Took the magaflows out in less than a week the drone was driving me nuts.

If you can get a couple feet of tailpipe after a muffler it helps cut down drone significantly. I have the muffler on my 928 in front of the diff. It's very loud, but has no drone. On my Audi the same muffler is right by the bumper and it's annoying at light cruise.

I have magnaflow on my '83 Euro S with MSDS Headers, hi-flow cat and 3 inch exhaust. It sounds great.
