ouch !

 

yeah it was mine, currently running w/o a muffler.

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.


Is this the 4 cylinder muffler? I am wondering if the V6 is the same. I thought it was a Remus muffler?

yes, its the 225 muffler. The V6 would have a simular chamber design which isnt a restriction on a NA motor

 

How is it without a muffler? Sound clips?

 

I'll try to get clips tonight.

I mentioned removing it a few weeks ago, and asked if anyone was interested in clips. Really was little interest, so I didn't bother.

 

ya, a T isn't the most desirable,i agree, and if i had more room on a fwdnot to do a T for dual tips i would have.but looks like aud decided that it was ok with the TT "T"exhaust,and you can get 300hp plus out of it.its funny, i got flamed by 225 guys about my T exhaust and they didn't belive that theres did the same thing on the inside of there can. APR's dual can is somewhat similar to the stock T,i saw a cross section in person at there headquaters in Alabama.its just doesn't have a maze for the exhaust to find its way out. most aftermarket mufflers still have alot of restriction to them, the only one excempt is the good old glass pack. any muffler that you can't see through does alot of twisting,turning,"T"ing and restricting. ive cut alot of muffelersopen for fun. also, a side note, my exhaust has quad tips now for a reason, the inner drivers side tip is straight out for the exhaust, but all 4 tips flow exhaust equal at idle. and ive noticed the T helps prevent pop and burp on a normal glass pack does after full throttle. and last but not least, if realy don't belive me that your high speed high flow aftermarket muffler doesn't have a maze inside, open it up and see how you were ripped off. noise level does not equal performance, noise equals length and the amount of noise insulation in the can. that being said, the longer the glass pack, or packs, the quiter and deeper the note will be. my 2 cents.

 

Its easy to tell the difference, its either a chamber or strait through muffler. I would only use a custom since i can tell whats in most aftermarket.

 

i agree 100%, but most belive if they pay alot, they will get alot, and btw, stainless adds 10hp.
