Just thought that I'd update this topic as I have been busy working on another one!

I have updated my equipment a little and refined my welding techniques to produce one that I am MUCH happier with!
I also wanted to add that both of the ones I have produced so far are considerably quieter than the factory originals that they replaced. The tractors are still loud at full throttle, but noticeably quieter than originally equipped.

I will have to commission you to build at least one muffler, for a Honda clone.

If anyone is wondering if these are really that shiny, yes. As a matter of fact, I saw Steve fixing his hair in the reflection about 10 times yesterday.

Steve, That is very nice work on the SS mufflers my friend. You have a new business in your future if you decide to follow through with it.

Great job on the 314 !! :thumbs:

I would appreciate the business Casey, but wouldn't and old tuna fish can with some holes poked in it work? J/K of course. We'll have to work something out!

I don't know why I bother...there's never a hair out of place!

Thanks for the compliment Brian! That means a lot coming from a fellow fabricator! I'd better watch myself though. George will start charging me for the "ads" :bigrofl:

Yes it would!

Looking good ! :thumbs: How many hours would you guesstimate to put one together?

Thanks for the compliment! That's a difficult question to answer. I'm a Married Father of four and I work on these when the opportunity presents itself LOL. I would guess that if I had everything organized and ready to go, It'd be somewhere around 8 hours. There's still some learning that I'm in the process of, i.e. order of operations to simplify things in the future. The cleaning after welding is the most time consuming part of the construction. Cleaning after drilling cutting etc... is the second. The finishing and polishing takes a good deal of time also.

Hello caseguy. Nice job on muffler.
How did you determine how many holes to drill in plate baffle and in tubes?

I don't really have a "formula". I just figure out what size holes I'm going to drill and how much space I have to work with and whether or not I want the exhaust to go in a certain direction for noise reduction purposes and lay the hole pattern out. Then I count how many holes there will be and figure the total volume of the holes versus the cross section of the inlet pipe size I'm using. It usually comes out to 3 or 4 times the volume. Occcasionally as much as 5. I figjre that the extra volume will make up for restrictions through the smaller holes and also compensate for some of the turbulence that's caused by the holes.
