Borla UEL Audio
 

I made a main thread about it with pictures and such, but I figured put it here so more people could hear what it sounds like driving some back roads.
Enjoy! (Sorry in advance for cell phone quality audio)

Any check engine lights ?

Holy God what is that nasty rattle in the first vid? Sounds like you've got some hardware bouncing around in there or something.

prolly just his camera rattling around while driving.

So.... are you gonna get one?

just the camera... it was just chilling in the cup holder lol

no... its only been 7 miles though lol

That sounds good :thumbsup: Has your ECU been reflashed? Keep us posted on the CEL

It will come on eventually

The o2 sensor basically is a 0-1 v graph, and rear o2 sensor should be fairly steady because of how the inside of the cat converter chemically reacts to the fuel air mixture of the exhaust, as the exhaust passes through the cat the cat reacts, gets very very hot from the reaction, and then once the air has gone through the cat it will have a very steady oxygen reading. Basically if your rear o2 sensor is a pretty constant voltage, the computer assumes cat is working great. but when the cat is removed, or stops working because it gets coated with crap, the rear oxygen sensor, goes up and down just like the front o2 sensor, and that's how the computer understands the cat has failed.

So basically its just a matter of time when the computer see's constant rear oxygen sensor voltage jumping up and down and then decide when to set a code after a few trips of failure

Does the car feel any different?

thanks for the info :)

cel came on within 30 miles, on my way home from autox today, car feels like it picked up a good amount of low end torque! I love it even more after autox today!! sounds like boxer should now :-P
