MagnaFlow D-Fit kits replace the restrictive factory muffler, while maintaining the OEM piping and tailpipe. The straight through design muffler or muffler delete reduces backpressure creating more power and increasing economy without replacing the entire exhaust system.

Q: is the magnaflow muffler delete 19476 long enough to take out the flap valves in front and behind the muffler Answer this question
A: The 5.3L that Magnaflow tested only had 1 valve which is retained with this muffler delete. There is a fitment note on this part showing it excludes vehicles with factory performance exhaust, so if you have a valve before and after the muffler, you may have the factory performance exhaust of 6.2L.
