Just contemplating where I am and where I want to go next?
I have the Saab Uprated ECU with new injectors, Open air induction kit, forge dump valve, what would be the next step?
What would the difference be?

Either a cat back free flow exhaust, or a decent suspension setup springs to mind.

Adam, you have made one of the biggest jumps in bhp already. Any future mods to the engine will start to really control and utilize the power that you have but will only give you smaller jumps in bhp. Your new performance is now limited by the amount of air that is going through the engine. My opinion on upgrades at the stage you are at would be in order of importance:

1/ Shocks and springs. If you put a set of lowering springs and shocks on your car you will eliminate some the Saabs famous body roll on corners and allow you to be in much better control at higher speeds.

2/ Set of fast road pads and if you can afford it maybe some grooved disks. The more power you have then generaly the faster you drive, better brakes better stopping power.

3/ Exhaust, at the very least choose a nice big cat back system, better still go for a complete system with a new downpipe and race cat, get those exhaust gasses out quicker, this will improve your spool up time no end.

4/ Boots, maybe a nice set of 17" wheels 225/45/R17. More rubber on the road, better grip and acceleration.

4/ Intake and delivery pipe, Again more air in to give slightly more power, better throttle response.

5/ Race intercooler, combined with the other mods this will really control temps, this for me was a really good mod, frees power and performance and allows much better and consistant boost levels.

Well the list can go on forever :roll: and cost a small fortune, but thats a few things to think about..

When you mention cat back free flow exhaust, are we talking about getting rid of the catalic converter? Is this legal for MOT's etc?

Cat back means from the cat backwards, so leaving the cat in place. Actualy my car passed emmisions last year without a cat in.. A credit to Saab me thinks..

Cool, does the section that connects to the turbo need replacing often?
Is there performance advantages available?

That'l be the downpipe, they hardly ever need changing, they are always very hot and dont seem to corrode.

Hi Guys, I've been looking at cat-back systems, Is there much difference between 2.5" and 3" systems?

 

[Kermit]

3" systems will flow more exhaust gasses, sound louder than a 2.5" and generally cost more to buy/custom build.

What you do with the cat back makes very little difference if you leave the stock downpipe and cat in place (other than a sportier sound). The Saab sport system at 2 and 3/8 inches is the best buy if you plan to leave the stock downpipe. The BSR system is very nice at 2.5" and they just came out with a dual exhaust as well! 3" JT systems have had some complaints regarding quality and fit.
