custom made muffler

so after a few long trips with the donor i came to the conclusion that i need to quiet it down if the mrs is going to be in the truck. i decided to make a muffler and put it in my bed since it will be hidden by my tool box, then the stack can come out of that. i looked at a few designs online then drew up a few ideas on paint. once i figured out which i liked i printed it out and figured out the dimensions for it. i made it 20" x 14" x 5". i was able to get some 1/8" steel plate for free from a friend so thats the route i went.

here's some pics of it as i was going.

with a standard sized tape measure in it







the top piece to close off i cut out where all the pieces were so that i could weld them to the top to make all the sexctions sealed off.


and here's a quick one of how it sits in the bed



it is SOO much quieter now. i can hear the motor while driving, not just exhaust. and that is with a stack thats about 8" tall and curved a little towards the rear. it will get a full stack once i get enough pipe.

this is what it sounded like before

and after

it cost me about 5-6hrs of my time. i only worked on it about an hour or so at a time while i could before i started on the project car. i know its not the best design for a turbocharged motor but i am more than willing to sacrifice 30 or so hp to quiet to the truck down and make her happy. those videos dont do it justice. ill get one of the local guys to post after they hear it.
