#gpgarage #homemademuffler #stainlesssteelmuffler
Hello everyone
In this video I show You how to make stainless steel muffler for car. This 3 inch muffler I made for my Bmw e39. I want build catback 3inch sistem on bmw e39 and this muffler is replacement for oem middle silencer.
In next video I will make full flow muffler for replacement oem back muffler.

Back in the old days we would be driving or hot rods and we would floor it then turn the key off and leave it full throttle for 2 or 3 seconds then turn the key back on the engine would fire that extra gas in the cylinder and blow the muffler off we thought that was cool.

[@mrmadunit3923]

We grew up in the most fun times .....I blew the pipe of my 75 xle cortina right at the manifold about 20 cm of pipe just ceased to exist along with our hearing for ages lol they were the days LOL

[@DontCallMeGarage]

did that once for way too long in my '67 datsun pickup, lifted the ass end off the ground.

[@mikecrawford715]

Very slick you put out some great ideas thanks for sharing!

[@VOETOM]

When we do it, we get the parts water jet cut. Maybe not as much fun but very accurate and quick! Thanks for sharing this.

[@GPGarage1]

You're welcome. Water jet cutter is definitely a better option.

[@lenness6689]

Nice job building it the only change I see is the baffle plate I'd step the overall circle diameter up or oval it to get enough holes in it to equal the area or greater then that of the inlet pipe.

[@vrm86gt]

agreed, that baffle plate is going to kill flow

[@davidmizak4642]

Nicely done! I have built my own mufflers for years. Cheaper than buying them.

[@GPGarage1]

Thanks. Definitely cheaper and I like to do things like this.

[@st.george9404]

so does the drone come from the design or from the two v plates only being welded on one edge?

[@Herbybandit]

It looks like it's made from some pretty thick material! Only things I'd change are some kind of sound deadening and drill some holes in the last flat plate to line up with the internal baffles so you can plug weld them in place 'cos I bet it buzzes.

[@GPGarage1]

Yes, it is a little thicker material than it should be. I'll see what it will be like when I mount it on the car, if I'm not satisfied I'll make another one.

Beautiful workmanship imagine how much money you have saved a lot of the mass produced exhaust systems are very thin steel i can see your mufflers would last a long time A++++++

Thanks man. This will definitely last a very long time, the only problem is the weight compared to aftermarket exhaust systems.

А верхняя крышка как то прижимается к лабиринту ?

[@demagchevy]

I wass really contemplating doing this, my only remark would be the plate with the drilled holes, I would think this is a restriction. If you wanted to do the same concept with the holes, but make sure your flowing the same in as same out same flow out.

[@GPGarage1]

Yes, plate with drilled holes is restriction definetly, but I think not to much.

[@MoparMan-ff8fb]

Great job but I would have figured to experiment and make a differnt style muffler instead of a flow master ? ive been doing a lot of research on differnt mufflers and how they flow and Slow master dont flow very well. I have sheets of sheet metal and a welder was thinking of expermenting and making the same case like you did but try differnt internals to see how they sound and flow . I had an idea you might try ? make a muffler like you did but instead of welding that strip of sheet metal down the middle on one side replace it with a sheet of plexiglass . then use a fog machine with flex hose hooked up to the inlet and a small shop vac hose to the outlet and turn vaccum on and then fog machine and watch how the air currents flow though out the muffler

[@GPGarage1]

I didn't do much research, the plan was to get a louder sound by replacing the original muffler. this muffler will definitely be an improvement over the original. If I don't get the desired effect, I'll try a different design.

[@JG-kv4oi]

@@jeremyking5684 Wrapped in steel wool is called a "steel pack." Magnaflow mufflers are glass packs and are quite popular and sound nice but most people think of a glasspack as a round body, 3.5" or 4" with a louver punched core although "Cherry bombs" are straight perforated core and considered glass packs being packed with house insulation rather than good quality high temp needled fiberglass like your higher quality muffler.

[@maloosecat123]

nice job, can flux core or stick welding be used to weld exhaust pipes?

[@EvilPyroCan]

Yes, I've welded it with flux core. But it doesn't look as "pretty".

thanks for learning how to made this exhaust,i gotta ask question,which side is exhaust entrance ?? and which side out?

Looks a lot like the design of a Flowmaster but I don't remember the baffle and internal pipe layout right off hand. If memory serves there's different layouts depending on which style of muffler. I thought about trying to make Flowmaster style mufflers for a 17 hp Briggs opposed twin cylinder just to see if it changes anything. Need to get a tig welder too.

Yes, I made it based on the flowermaster muffler, but I didn't copy it 100%.
