Here come last restoration story about Saab -62 UrSpecial. I hope least some of readers has get inspiration and usefully hints when repairing own TwoStroke. As this restoration has been more or less respect for the cars fantastic Saab history, I made a lot of work also with original exhaust pipes which I get loose with the car.
Many of you readers should have chosen more simply way by byuing brand new pipes for example from XP- Niklas; www. classicsaabracing.com , but I feel more challenching to repair those old rallypipes I got with the car; how knows if those has been fitted for some Works Saab Sport in 60´s ? Anyway they looked well and hard used. There was one main problem, the pipes and mufflers where damaged baddly and fitting to the car was not possible without some extra work. To manage this, I let lokal machining workshop made some special tool for remolding the pipes and mufflers.

Strenghtened Saab Sport exhaust pipe was smashed underwards and disassmbled out. Former owner has saved a lot of spare parts for the car during past 50 years. Thanks for that, I have possibility to reinstall many original parts to the car.

Thanks for living countryside, handy machining workshop made me special tools without any complicate CAD drawings, I just explains my needs.

The only way was to tapped dents outwards by using special tool which was round 1mm smaller diameter as pipes inside diameter.

After hammering tool inside the pipe, dents were mainly straight. Tool get out when hammering backwards to the tool shoulder.

Front silencer need its own tool with another dimension. I find out this good method to fix hole system back to duty.

Third special tool was machined iron bar, which I used when bending right angle to the douple pipes front.

Just some smoke comes out. Enought to finish painting but far away what need when cleaning 2 storke exhaust´s inside.

Kosan gas rules. All the twostroke stuff burn out and hopefully the system serve now some extra horsepower vs. doing nothing.
