    I'm in the process of reviving 12685 from a long and neglected storage. Since I acquired the car in February, I've been doing some basic tune up and service to get it road worthy.

    I will start a thread summarizing the "revival" in depth.

    The previous owner managed to damage the exhaust due to the low ride height. The exhaust is stainless but does not show any markings that would indicate the manufacturer. Two of the "cans" on the driver's side are split. There are some pieces now missing or broken off as a result of shearing over speed bumps or other road hazards.

    Who would be the best source for a replacement section of the system? Also, I'm considering the fabrication of a custom system using some, off the shelf components and leaving the existing system off of the car.

    Any advice is greatly appreciated.

    Thank you,

    Can you shoot some pictures, it may help identify the maker of your existing system. Also, try to find a custom muffler shop in your area, if you find a good one, they will be able to fix what you have.

    I recently restored my 330gt and decided to run with the Stebro stainless system.
    The price was fair and the system fit pretty nice overall. The muffler shop that installed them used a bit of heat in a few places to get a relaxed fit on the flanges and to also square up the exposed tips. Definately not a simple bolt on, but not alot of extra work to fit either.
    With regard to the sound, I would say that the tone is right in there with the original Ansa system. The car has a good sound.
    The material used is not a real high grade of stainless, but it is nice to have even this grade of ss for the longevity. Overall the Stebro was a good choice in my book!

    Thank for the replies. Yale's post showing the Timevalve link may be the ticket as only the center mufflers are damaged.

    Perfect, thank you.

    We had an exhaust 'guru' build us a new stainless system based on the rusty old one. If you can find an 'old school' exhaust guy in your area that may be an option for you - us being in Australia meant that is was vastly cheaper to go this way rather than trying to import one for the car. Check out too for some helpful links and info!

    Guys, after examining the exhaust more closely, I decided to repair the existing system.

    On the forward driver's side muffler, the front edge was damaged from road hazards. It was split and peeled back. I cut a 5.5x8 inch square section out of the muffler. I picked up some scrap T304 and with the help of a local FChatter, we welded the patch on. It looks pretty good and the leaks are almost all gone. We will revisit one night this week.

    On to the valve cover gaskets...

    Thanks for the insight!
