I got a little bored the other night at work, and this thing was going in the scrap barrel anyway, so I figured I'd do a little exploratory surgery.




Double walled.


Fiberglass packing


Steel packing underneath the fiberglass.


One end of the muffler, other side looks the same


Perforated tube under the steel packing


Huge restriction here


Total view of everything opened up.

Comes into the muffler, 'T's and heads to the ends of the muffler thru a solid tube. From the ends it does a 180° turn back thru the perf. tube to exit on the side opposite from where it originally started.
Another restriction I didn't show is where the pipe exits the muffler. It's 2.5" stainless pipe starting about 1" outside the muffler, but where it's welded to the muffler, it's necked down to roughly 2" diameter. Interestingly, it's more like 2 3/8ths pipe coming into the muffler, which will make things slightly interesting when I try to line up a 2.5" pipe to weld the stock tips back on with the DOM pipe I have coming. I can do it, it'd just be easier if it were the same size, for alignment purposes.

 

Nothing flows better than a Tee!! Wow, thats not the first time i have said that....*cough* sttjacket *cough*.

Thanks for the pics Matt. Sttjacket chopped his fwd muffler and it was awful also.

 

really? missed those pics, when was that?

Oh yeah, I weighed it too, 35lbs including tips.

Tips, cut from where they exit the muffler, are approx. 2lbs each.

 

It was his infamous triple Tee exhaust

fwd muffler

 

Nice.

If it was a 'tex post, that would explain why I missed it. I actually prefer AW over Vortex most of the time.

 

Oh, its legend made it over there.

 

Now that's effeciency, and lightweight also! Shows why one of the first mods should be a free flow exhaust.

 

niice ! how many miles did that beast have on it?

 

139,000 assuming it was original to the car. Was starting to develop cracks around the welds for the hangers.

 

Was that yours?
