I decided to change the exhaust on my Countach and checked out a few. I ended up buying one from Stebro. I spoke to Dan Petschinig at Stebro and he seemed very accomodating. He asked if I would send him my original exhaust system to use as a model to produce an exact fit. He would reimburse me for the shipping costs and return the exhaust system to me. So I did this,and several weeks later, I received a new exhaust system that was not made exactly as it was pictured. I called Dan and he said no problem, He had another customer that needed that exhaust system for his car. Dan asked if I would send that system to his other customer and he would again reimburse me for the shipping costs. So I did that. I spoke with Dan about the new revised system that he would make and several weeks later, I received the second exhaust system. It was again wrong. He made it in 2 pieces instead of 1 piece and forgot to weld in the bungs for the ECU sensors. I called him and he said no problem, send it back and we will take care of it, including shipping costs. So I did that. I sent it back and several weeks later I received the exhaust system back and it was correct. It was made in 1 piece and had the bungs welded in to receive the probes for the ecu's. I installed the system and it fits very well. No complaints about the exhaust system. The problem as you might have guessed is that Dan Petschinig from Stebro promised me multiple times on the phone and through e-mail that they would send back my original exhaust system and reimburse me the shipping costs but they never did. I have been lied to bluntly, over the phone and through e-mail. I have been after them for 2 years and now they don't even reply to e-mails any more. I thought that Stebro was an upstanding company but I am wrong. I would never do business with them again and as far as I can tell, they don't want me either. If anyone decides to do business with Stebro, I would not suggest it, They did not keep their end of the bargain and I have nothing good to say about their business practices. I am in the US and Stebro is in Canada, so the law gets tricky and expensive. I have not pursued it any farther but decided to expose this injustice.
