Wonder how many cars that is, 10, 15? Dont know. There arent that many Viggens around here....:) Yes I would say that Nordic is well know. Most of their customers are compamies, ie company cars. Private persons often turn else where due to the extreme prices. Pros and cons for Nordic (hopefully objective) + Has been around for ages, are only working with Saab + Working close with Saab dealers, many new cars are actually delivered by Nordic directly to the "end user". + People who ones stared using Nordic mods seem to continue to do so. - The prices. I can assure you that the Nordic mods (Trionic upgrades etc) are not better than the ones you can find from the other tuners (see list bellow), so its not a "you get what you pay for"-thing... - In my personal opinion, Nordic are #1 when it comes to marketing. Their success (no doubt a successfull company) is just as much the result of good marketing/profile as having good products. In short: Technically, the nordic mods are not better (or worse) than any other prods, but they have found a way to get paid for it like no one else. Excellent customer service may be part of the answer. - Some people with close connections to saab (engine development) seem not to like the nordic stuff. Dont ask me why. - Still only (I think) sell their mods as complete packages. To get the ECU upgrade you also have to buy the stainless steel exhaust (=> expensive). Why dont they let me buy my own 3" exhaust? I hope this helps you is extremely hard to decide what tuner to use....even for us locals.... A list of other Swedish tuners with a good reputation amongs most people (my reference here is the members of the Saab Turbo Club of Sweden): (technically skilled, will test their mods for my car asap, decent prices, I like these guys) (this is what I use for my DI-apc 9000 Aero -91, very nice) (check their site, extremely dedicated to their business, also politically involved regarding emissions etc) (reputation similar to Nordic, but not at all that expensive, does not focus on maximum power but rather to have a drivable car....) All these are dedicated to Saab tuning. I think (dont know for sure) that BSR has the biggest market share, followed by nordic and then all others.... > > > I was reading an article in an Australian speed magazine and the author > presented a table of engine Kw versus diameter.

Your comment "behind the cat is not > important" implies that the exhaust gasses loose temperature in the cat, > thus smaller pipes are sufficient. Did I get this correct? > Yes. Gasses looses temp not only in the cat, but all the way from the turbo (of course), 2,5" pipe is sufficient behind the cat. Having the least possible backpressure is the best thing for turbo cars, provided the engine management system can handle it. Saabs can. For me, the number one reason for using a large diamter exhaust and a high flow cat is not the performance gain (although nice) but rather the lower operating temperature for the engine and turbo. This it self will not only let the turbo live longer, it is also good for performance...
