It depends of course the material the manufactured from. magna flow gives you 2 options. Where borla starts out w/ t304 stainless. FYI a Fwerks "stealth'' is a magnaflow muffler. I have a stealth ahead of my borla system, & it sounds similiar to a stock st. 1great thing I like 'bout the stealth is where they weld the connecter, real tight to the flex. And w/ that theres rooom behind for another muffler, which is where I have my borla muffler. Or you could use 2 stealth mufflers in line, which I have yet to hear.
