Custom made 3" exhaust system

Rotary Heart · 10-06-2011, 02:58 PM

Well I think that I'm going to introduce my exhaust system here.

I have a aluminum 3" exhaust muffler from Vibrant. And the rest of the exhaust pipe is mendrel steel

Weight of the custom made pipe without the muffler

Weight of aluminum pipe its amazing!!!!

Weight of stock muffler, its unbelievable heavy!!

And weight of the stock pipe

Dam I will love to make the full pipe in aluminum!! who knows maybe coming soon

Now here's the complete work outside of the car. Hope you enjoy it!

This is how it will go in the car.

Here's where the LSD will go, thats why it have that angle. You will see it soon

A really straight pipe

Here's the reducer from 2.25" > 3"

Non cleaned aluminum pipe.

Cleaned aluminum pipe.

And here's a little video of the exhaust pipe.

An aluminum muffler on a car? I cannot imagine how that will not at least warp with that exhaust gas volume and temperature. Aluminum goes to liquid at very low temperatures compared to steel.

Ever heard of alloys?

Its not like its a header man. Aluminum melts at 1220 F, the muffler will probably reach temperatures not much greater than 300 F; sure it'll expand but it wont deform.

I doubt that the exhaust is over 1220*F when it hits the muffler.

i have only herd good things about vibrant'

Rotary Heart · 10-09-2011, 08:46 AM

I have had the aluminum muffler for a year and it haven't have any problem. I don( believe that the muffler will get to 500f... After a hard drive I have been able to put my hand on it (the aluminum get cold super faster)

hnguyen037 · 10-09-2011, 11:05 AM

aluminum is fine for an exhaust system. it doesn't get hot enough to melt, and dissipates heat pretty quickly

95MerlotM · 10-09-2011, 11:57 AM

looks like one hell of a hackjob but the end result looks pretty damn good!

Rotary Heart · 10-09-2011, 02:27 PM

This is a prototype to make it 75% aluminum. You guys will see when I have all done

DazedAndConfused · 10-09-2011, 02:40 PM

This actually sounds very good for no resonator. Smooth and quiet also

ComicArtist · 10-10-2011, 06:47 PM

Looks good, can't wait to see the finished product.

That looks more like crush bent though, rather than mandrel.

DazedAndConfused · 10-15-2011, 09:37 PM

Which muffler is that from Vibrant? Is that a 3'' pipe on both sides?

Yes.

DazedAndConfused · 10-16-2011, 03:49 PM

Where did you find aluminum exhaust flanges at or did you make your own? Sorry for all the questions but I have the same muffler and never mounted it.

crespoh69 · 10-16-2011, 04:25 PM

wow that is a huge weight savings, anyone know what this sort of setup would run us Cali folks to have made up by a shop?

DazedAndConfused · 10-16-2011, 04:33 PM

You can find all the piping, resonator, and muffler online for pretty cheap. The muffler goes for about $100, resonator $50-60, and the piping is pretty cheap too. I just can't find any damn aluminum flanges.

I buy a iron one and make my own in aluminum. If is takes to you to long to find one I can make you one, but it will be a little high price. Let me know

Rotary Heart · 10-16-2011, 05:22 PM

Or tell me how much you want and I can make them for you.

Oh, it's aluminum alloy. I forgot there were two kinds of aluminum. Thanks

Yeah, it's a good thing they don't make engine blocks or heads from aluminum...

GOOD THING!

any new updates on that wood engine?

1993ka24det · 11-03-2011, 01:21 PM

I'm was thinking of doing a Aluminium Cat back exhaust with no Cat, but I can see alot of people saying ALUMINIUM WHAT!! for an exhaust system

Who did you get to weld up the aluminium, was it vibrant?

dontpassthefence · 11-03-2011, 02:32 PM

aluminum is a good idea if you arent concerned with corrosion, its a good temporary solution for weight savings.

DazedAndConfused · 11-03-2011, 02:39 PM

Not a good idea if you are slammed. lol
