So far I have equipped it with Magnaflow performance cat back exhaust leaving only two cats, the ones by the downpipe, and a k&N air filter.

I previously owned an AUDI A4 with lots of mods.

I live in the USA and learning about these vehicles is a horrid task =/


Anyone know of any good SAAB performance sites?

Does anyone know of a good BOV, Late throttle release sometimes results in clattering noise due to backpressure of turbo..

The car is ok.. the more I drive it the more I like it. Nothing compared to my a4 though, that is for sure.

The front end / suspension.. is horrible.
The front breaks should have been put on a geo metro.


The styling isn't exactly to my liking..

Other then all of that, this car is my new baby! haha


Im going to mod it, drive it. Simple as that! For a 2.3T it's fairly slow hehe.. Ofcoarse after the intake and the catback it breathes so goood. I love it! I've actually got the srt 4 sound to my car. Just a tad louder though

Is there a safelist of BOV's from our users?
No BOVs are "safe" on our cars... the engine management detects it as an air leak and throws a check engine light. Some valves have worked before, but they do tend to make the car run worse, so why bother? If you are looking for the "PSCH" dump sound, you can always swap your intake for an open airfilter:

If your stock bypass valve is worn out, it will make some hooting noises after you install the airfilter. This is a good time to install an aftermarket piston style bypass valve:

http://www.genuinesaab.com/catalog/product_info.php?cPath=47_53&products_id=463
http://www.stratmosphere.com/hyperboost.htm

I personally have the old stratmosphere adjustible bypass valve, which lets you screw down some preload on the valve. This is similar to how the forge valve has different springs you can install for adjustment. Because of this, you can also install the valve in a reverse fashion (i.e. the air presses from the delivery pipe on to the bottom of the valve). I have been trying this out for about a month now with some interesting results... the sound is definitely improved and much less "chuffy" sounding, and a much quicker release. At certain throttle angles you can cause the valve to flutter when you come off the gas. Surprisingly though I haven't noticed a performance decrease, in fact the car actually felt faster at times until it adapted.

Because the vacuum line on the bypass valve is never pressurized (it only gets vacuum up to 0 bar), you have to rely on the spring providing all the resistance against the boost, so I have mine cranked right up in order to not leak at 1.2 bar. I think with the Forge I would probably use the stiffest red spring as well, and maybe even shim it with a washer.

If you want to go with a more stealthy setup, you can just use the stock airfilter and the new snorkel for the exact same performance, and it's much safer as well.

The brakes on the Aero are pretty decent, but you can improve them quite a bit with a good set of pads. Axxis ultimate ceramics, EBC redstuff and Hawk HPS are all good.

The Aero suspension is also decent, but the shocks are horrible. The rears wear out really fast and they are all around way too soft for the springs. A set of Bilstein HD shocks from shox.com will absolutely transform the cars handling. Amazing performance, but REALLY comfortable.

With your exhaust setup, your car should be able to go up to stage 2 right now, though I would personally invest in a downpipe and intercooler and go straight to stage 3 instead:

http://www.genuinesaab.com/catalog/product_info.php?cPath=47_53&products_id=478

If your model is a manual, this modification is also very cheap and will highly improve your shifting feel:

One non-performance part I would recommend to everyone in North America is this:

http://www.genuinesaab.com/catalog/product_info.php?cPath=47_54&products_id=41

The blind spot on the driver's side is huge, but with that mirror it disappears completely. I have much more confidence driving in traffic since installing that.

Brakes?...Decent?...I would go so far as to say they are excellent with the right pads. These brakes will pull fillings out out your teeth.

I remember reading somewhere that a 9-5 Aero will stop in a distance similar to a BMW M5. I know that the stopping is certainly comparable to 330i that I had and better than the A6 2.7t that I had before that.

Correct me if I am wrong on the M5 comparison.

Thank you so much for all of the feedback. I just got my car back due to a serpentine belt break. Was on the highway and lost power steering. =X


Anyone else get an srt4 sound?

How do I get around the two catalyic converters by the down pipe? It's all straight piped from there.. I really would love to know how it would sound without those.. My oh my.


The car unfortunately is automatic. The turbo lag, must be aprox. 2 seconds after each gear =/

There is only one cat... the other thing is a flexpipe. The Genuinesaab downpipe will replace the cat with a high flowing 3" piece, and it replaces the flexpipe section as well. Changing the downpipe drops your exhaust note a bit... but the main improvement comes in additional power and reduced turbo lag, especially when you add in the ECU.

I would not recommend running without a cat. It will throw a check engine light and the car will perform worse.

are we talking about the stock system? i thought there were two cats, one right after the first O2 sensor and one right after the flex joint. see below picture...






the GS downpipe has only one cat positioned right after the flex joint. they deleted the cat after the first O2 sensor for freer flow...






....and the sound with the GS downpipe is deeper and has more "growl" than the stock dp. an upgraded catback makes it sound even better. :cool:

Yes there definately is two cats around the sensor. Which is why I left them there until I can get a downpipe.


I think my first margins for mods will be the downpipe and the intercooler and then the ecu upgrade.


Anyone know of any great interior accents I could get for the car? There are many things I would love to change including the wood panel, shift stick/knob, instrument panel gauges.. steering wheel..


Exterior I'd like an aftermarket grille... turbo badge.. and some kick *** headlights/tail lights..

I've searched high and low and have yet to come across anything of the sort. :]

The second "cat" that you are talking about here is a center resonator. It can be replaced with a straight pipe, no detrimental effects.

Not as good as an A4 huh? that's odd, most like them more... but it sees like you need to upgrade the suspension if you want a differnt ride...

There are not Modded lights froot or rear, many will repace them with the newrer 2005 midel fron =t end and smoke the rear tails ( but that is kinda old school now.

If you go to the State of Nine website they do have Stainless steel mesh grills for about $500.

Most of the interior accents (woodtrim) can be replaced. Look at the Flash your Dash thread. I personally like the Carbon fibre look but don't have the $$ to afford to do 'whimsical' upgrades. ;)

there are indeed two cats in our exhaust system, although only the first one is really needed. there are also two "mufflers", the centor resonator which comes after the second cat and the rear muffler. technically, everything after the first cat can be replaced without causing a cel.

as for the rest of the mods check out: parts for saabs, genuine saab, and thesaabsite. you'll probably find all the stuff you're looking for between those sites. good luck & happy modding!

I must say.. I am largely disappointed with the aftermarket available for SAAB.


Anyways.
Some more info on my SAAB

2001 SAAB 95 AERO
Magnaflow Cat back exhaust
K&N Filter
Blue
73,000k Miles

Uploaded video onto Youtube for exhaust.. Will be processed shortly!

Adding next : Down pipe, Inter cooler, ECU
