Thank you all for your information, Ed, your info about the balance pipe interest me (good for sound and balancing exhaust pulse). Your advice about the construction will be considered. Is a flexibele pipe an option? JZRIV, I think you are right about using aluminisized pipes in my situation. I have to get in contact with Waldron for costs including shippingcostst. Plus, somehowe I want to know the way it sounds. Bernie, I can not look into the future but my guess is that I won't sell this car in the near future. The way my car is used by me,it won't have a hard time I hope... Steelman, I am very interested in your exhaust system. It is silent! I would like to hear the sound. So, again, I am very greatfull to you all. Have to do some research now about the different options and sounds. I have to visit some shops in The Netherlands. Best regards,
