Review on TOTALFLOW TF-SY2525 409 Stainless Steel 2.5 Inch Y-Pipe Single / 2.5" Dual (Inner Diameter) by Matt Lewis

These are not as nicely-made as the Magnaflow versions. That is, the Magnaflows seem to be more "visually" streamlined. Whether they're actually a better-flowing unit I can't tell.I used this to connect a single-inlet muffler and tailpipe to the twin catalyst exhaust system my '97 K2500 7.4L came with. A previous owner installed a crappy mild-steel "cat-back" system that had totally rusted-out. Because space was limited, I had to cut the three stub pipes (2 inlet, 1 outlet) on this unit back about an inch each. Then it welded nicely to the rest of the system.
