Muffler madness

[OldGoat]

The muffler is a great idea, I used a racing muffler from Jegs high performance to keep is low profile. just be sure to use high temp paint ! what you see is the brown promer not rust. Now I figure to let the paint I used burn off and then apply the high temp kind.

Any more pictures of your M52a2? I have one also, yours looks great.

You can't have a muffler and not increase the back pressure, even the straight throughs. There will be a small drop in power along with a slight increase in EGT's.
I am going to get my bobbed deuce dynoed as soon as it is operational again. Can't find a dyno for my tandem truck.

Anyone ever route the exhaust and muffler under the truck? I'm considering doing that due to clearance issues with my garage door on my barn (cheaper than building new barn.) I got the new muffler and even with cutting the pipes shorter and still being able to secure it it is too tall to park it indoors. I have to removed the whole stack at the fender to get it inside.

so has anyone used a db meter to see the actual drop in decibles at 50mph?

Inquiring minds want to know

 

[saquishmike]

I think the gas jobs run the exhaust under .

They do, try searching this, much to read, all this has been gone over many times.

i have a 3.5 inch racing muffler on mine from jegs .its a full flow muffler it sits under the shield and looks factory you can hardly tell its there by looking but it cut the noise by about half you can talk to eachother without yelling even while on the highway

actually the muffler added power to my truckby making more heat the turbo spools up at a lower rpm so it gives more boost and more power throughout the power range its a racing full flow type that flows ten times more than is needed for a 2600rpm motor i noticed the difference as soon as i put it oni turned the fuel up till i got black smoke that was before the muffler and now with the muffler my boost is just under 30psi

I have been thinking of doing this mod

what jegs muffler did you use, got a part #

 

[avengeusa]

was it something like the one on this page?

Dynomax 24216 - Dynomax Race Bullet Mufflers - JEGS

and how do i know if my egt is too hot, i have no pyrometer, i am concerned with that

Put in a pyro. If you cannot afford a pyro, you cannot afford to play with the motor.

I installed the walker 21470 muffler on my deuce and the results were better than expected. I dont have to wear ear plugs around town and you can hear the turbo no problem.

so where does one get a pyro, and which muffler is better to use, the glasspack type, or the walker one everyone seems to be using?

 

[jatonka]

Avengeusa, I use the Dynomax 24216 in my upper stack on the M109A3 that went to The Pacific Ocean and back, 7000 miles in 28 days across the USA on US Route 20 and back on US Route 30. It has a stock, LDT-465-1D engine with 1D turbo. I burned diesel fuel and did not turn up the pump. I pulled a 105 trailer with clothing repair shelter mounted on it full of tools, fuel and 4 men's gear over 3 mountain ranges. No problems at all. I could talk to my rider through the whole trip.

i heard about a drop inside the stack type mufler...anybody else hear bout it or use one?

 

[crazyplowboy]

I would think that a drop in muffler would restrict the air flow resulting in more back pressure and higher EGTs

 

[OPCOM]

Whatever kind of muffler Sermis used, it was very quiet as well. Napa something I believe. My concern is cutting the stack pipe. Is there a way to preserve the stock connecting flange?

 

[cbvet]

JATonka,
Any chance you could post a picture of the Dynomax muffler installed?

[avengeusa]
