Anybody have video of stock exhaust w/ 3" downpipe?

[arekieh]

Anybody have a video of a 9-3 Aero stock exhaust but w/ a 3" DP?

Trying to get a bit more sound out of my car on a budget? Don't want it to be loud to the outside but I like engine/exhaust noise (radio... not even once).


Was thinking of going straight pipe but I don't want it to be drone.

this might give you an idea, stock exhaust but with catless 3"D/Pipe



{ignore the speed, its much quicker now}

Sounds pretty good, nice and deep but not too loud I like.

I think I'm going to do it. Did you take out both cat's or just the one?

Do you have emissions testing where you live? Not sure you can pass emissons testing without a catalytic convertor

Nope no emissions testing. And if they change it or w/e I can just throw the stock on back on can't I?

i got a good clip but dont have it with me...ill post it on monday when i get back home

[arekieh]

awesome thanks

I don't see why not.


I wonder if you need to reset the ECU when switching exhaust systems? Don't know all that much about it but backpressure change might affect engine management I would think.

removing the first cat will throw a cat inefficiency code, but that shouldn't do anything other than have a CEL on. there should be no issue swapping back and forth (other than the pain of actually removing/installing it).

Won't the computer try and correct the air/fuel ratio to try and make the non-existent cat try and perform? Even the BSR downpipe has a cat intact. Maybe it's a biiger diameter and that's a (expensive) wat to go.

And I know it's only one car per person but I am of the opinion we should think globally and act locally about the environment and leave the cat on.
But we all choose our limits, I am a hypocrite, my Aero only gets about 21MPG!

If anything it would make the car run a little rich. Very lean mixtures cause the NOx emissions to increase, so it shouldn't harm the car really. The cars fuel mixtures are controlled by the first oxygen sensor that is ahead of the cat,
so removing it doesn't really affect the engine outside of whatever it is programmed to do when the cat fails. If you intend to tune the car, you can have this system disabled entirely so you only see the benefits i.e faster spool, louder noise better airflow through the engine = more power.

I didn't think it would harm the car, just the air. That's why they've put cats on since the 70's

This is the route i have taken

Tune should be here early next week . I'll email John as well and see what he thinks.

I'll post a video later today. Just got the Saab back 2 days ago.

Here is a video with the midpipe and downpipe.

[arekieh]

oh man, that sounds awesome.

Did you install them yourself?

And these are the two you installed?

I installed the midpipe myself and had the cash only shop across from work do the downpipe. The linked parts are the same. The midpipe was a little longer than the stock one. This is why my tips stick out past the bumper.

[arekieh]

Ah ok,

How much did the shop charge you?

[Hutch06Aero]

$150. The only issue was O2 sensor clearance on the heat shield.
