Chevrolet Silverado 4.3 walker muffler

  • 11 years ago
This is a stock single 2 3/4 exaust pipe with catalytic converter delete and a cheap walker soundfx muffler.

I'm happy with it, 55$ and it just quiet enough. Sadly I can't say what did what as far as sounds goes since I removed the (internally shattered) catalatic converter at the same time.

It sounds better than stock but I don't know if it's louder because the cat is no longer there or if it's the muffler that's louder.

first vid: open loop (cold start)
second vid (closed loop, o2 sensor kicked in)
third: rev to 3k
four and fifth: acceleration with and without clutch
