Nope. Flowtech takes the cake on worst quality exhaust parts.
MAC was OK.
I sold a lot of their product. It was a bit better than OK. Light years ahead of Flowtech.
I dunno, i had 2 sets of mac headers, a mac H pipe and some idiot swapped out the
borla catback on my saleen explorer before i owned it with a 3in mac catback (it was a 5.0 SC truck). Having had a mustang with flowmasters at the time and a truck with a mac muffler the sound was awfully similar and the drone was horrific.
Not one of those four products survived. The catback actually leaked after the muffler and damaged a bilstein shock.
One set of the mac headers rotted in the collector, could never figure out where the leak was, then i completely removed them and if you held them up to the sun you could see all the cracked welds. The other set didn't have a full flange and risking removing and reinstalling them was a task.
I don't know much about flowtech, but i stand by my opinion on mac parts.
I was younger and on a tighter budget, but still never again.
It's stainless for me now. My bassani equal length headers were like a work of art compared to the mac set.
The X pipe is nearly indestructible.
