muffler exploded

my black 90 sc backfired the other day from a faulty dis module and took out the muffler, it was so powerful that it tripped the emergency fuel pump shut off switch.

pics tell the tale












lesson learned... don't ever buy those cheap rinky dink thin aluminized mufflers

yep it was the dis, i kept priming her trying to get her fired up so fuel vapors were resting in the muffler since its the only restriction in the exhaust

theres a plethora of oxygen right outside the exhaust pipe, from cranking so much a spark made its way to the muffler and ignited the vapors

hell yeah it was loud, a fireball shot out and just echoed for at least 2 seconds

neighbors came running outside because they thought a bomb went off... that says something since here in uptown new orleans people don't even bother with gun shots.

No, there was O2 mixed with the fuel INside the pipe; otherwise it wouldn't have exploded. Chemistry is a *****.
