It looks like the new tech article at MustangExhaust.com will be about the magnaflow catback......
"Just wanted to let you guys know what's in the pipeline here at MustangExhaust.com. As a follow up to our successful H vs. X tech article, we will be putting Magnaflow to the test by recreating the Hot Rodding magazine muffler test mentioned in the tech article. We'll be buying some weld-in Magnaflow mufflers and putting them on a stock 2001 Cobra just like in the magazine article and then we'll hit the dyno to see if we get the same results. If we even get half the power gains they got (~20 rwhp) I'll be very happy."
