A VIN, and the reason why a muffler is an emissions device...
Posted 14 November 2003 - 10:52 AM
And now for the muffler.
Im getting 21.7 MPG now. I HATE it. I was getting 29MPG!!
Reason: I installed a factory 4wd exhaust system to pass emissions.
Now, usually, the max allowed CO readin is 220, and the last time i got it inspected, the reading was way up there (sometihng like 218 or so), and I had a straight thru muffler. IE no backpressure. 29 MPG.
Now...BIG backpressure, stock muffler, quietness, and pass emissions with 81 CO reading, and LOW LOW MPG now. So, Back pressure, low CO, and the sence came to me.
The muffler restricts the air from flowing out so quickly, that way the air stays in the cats for longer, giving the honeycomb and the exhaust gases more time to interact, much longer, therefore the air comming out of the cats, are cleaner than before.
Thats my spin on it. I'd still rather get more MPG tho. I AM switching to a 3 way cat on the GL-10 when I get some more $. The RX will get a 3way, as its sitting here waiting to be installed.

Remove discs to decrease the exhaust opening and increase back pressure.
-This decreases the powerband to give you more low-end torque.
-Decreases the exhaust tone.
-Enriches the carburetion.
Add discs to increase the exhaust opening and reduce back pressure.
-This increases the powerband to give you more top- end.
-Increases the exhaust tone.
-Leans out the carburetion.
I learned about them at www.subarubrat.com
You could also remove disks to pass emissions and then add them for actual driving

My education is based on stock EA82's.... so I guess it varies.
You learn something new every day.
Now I will I be sober enough to actually retain this??
