I have a 90 GT and need to get an H pipe with cats. Whats everyones opinion on Mac or Magnaflow, the Macs are quite a bit cheaper is there a real differnece between the two with quality and what about fit has anyone had problems installing either. Thanks.
A mandrel bend is a mandrel bend. I put MAC on my Cobra and LX with no regrets or fitment problems. Why pay more for something no one looks at. The MAC's sound every bit as bad as anything out there. Save your money and spend the extra on future mods.
I have Magnaflow with long tubes and no cats. I love the way it sounds. It sounds much different than any other 5.0 around here. But I worked for a place that was a magnaflow dealer when I bought it so I got a great deal.

I have no "lines" in my MAC mandrel bends. A mandrel bend leaves no lines. If you want to feel better about spending more for a product that performs no better be my guest. The primary reason for increased prices of exhaust products is stainless vs. aluminized and brand name glitter.
on my MAC cat back the design was VERY good and all the bends are extremly nice, no lines or anything, and they sounds pretty dam good with the stock h-pipe, no one looks under my car because it sits to low to the ground so i have aluminized, stainless is a waste of money because no one sees it, but i do have chrome tips that look very good
Stainless will last longer but I'm not sure if the cost benefit analysis works out. How many times will you have to replace your aluminized before it cost more than the initial cost of stainless? Also in theory we all love our stangs but in reality most are traded off for a newer one or a family car before even aluminized wears out. The Walker dynomax mufflers that used to be on my LX were over 10 years old and still worked fine. I just decided to replace them. The choice is much like women, all men have their preferences. Do whatever floats your boat.
I've got a Magnaflow catback, (been on since November) and the last time I was under there, it looked like there was surface rust on the pipes. The rest of my system is Mac - headers, H-pipe. I think Mac makes decent stuff. My previous catback was Mac, and it had been on the car for well over ten years - in the rust belt of Ohio. It did finally wear out, but I'd give any Mac product a try.
