Making a set
of Exhaust Cut Outs
from Oil Drum caps
Written by Mike Martin
I purchased a
set of flowmaster 2 chamber (loud) style mufflers , but all my friends
know that's not gonna be near loud enough for me. I made my own invention
of the "DUMPS" effect , but still keeping your stock tail pipes
I took the mufflers and had a 2 1/4" hole cut out on the exit side
beside the tail pipe.
Then I went to the local oil drum grave yard and CUT the entire seal off
the top of a 55 gallon oil drum (Threads and cap both)
I cleaned up the caps and outside threads on a grinder . Note:
I used stainless steel oil drums so I knew they would never rust.
Third is the rear view of both opened up.
I had the local muffler shop weld the outer threaded ring to the hole
on the muffler. There you go!
The sound is the Deepest and loudest/clearest in any car I've ever been
in that still had its 6 cats on. That's right , the factory H-pipe is
still on. Not raspy.
2 stainless caps that will not leak period. - Mike
Note: To re-cap (no pun intended :-) These
are stainless steel caps from oil drums that were cut from the drums
in a junkyard and cleaned (threaded ring and cap), the threaded
ring and cap were then welded into a cut hole at the rear of the
muffler by a muffler shop.
To open, you
simply un-thread the cap on both mufflers.
