This is a de-cated stainless steel downpipe with CNC machined stainless steel flanges and is fully TIG/Argon welded and every production steps have been taken care of, so the fitting and finishing is just as perfect as it can get.

Please refer to the above illustration, just in case some of you don't know where the downpipe/ dump pipe located at the engine bay of your Toyota Caldina GT4 (ST246)....

  1. what size is the downpipe 2.5 - 3 inch?

  2. Yakamo, the size of the downpipe is 2.5". Thanks.

  3. Hi thanks for that,

    is there an option for 3" inches since bigger is normally better for turbo cars?


  4. Yes, Yakamo. We can specially custom made a 3" downpipe for you. Please proceed to SuperCircuit Exhaust Pro Shop for more information. Thanks. - Frank.

  5. so this is just a straight old one out new one in?

  6. The downpipe is straight bolt-on, no modification required.

  7. Do you by any chance ship over to Australia?

  8. Will this downpipe bolt up to the st215 caldina turbo as well? I have an st215 in my mr2 and need a downpipe . Can these be had with the 3bolt flange to mate up to an mr2 catback exhaust? If not I would still purchase the one as shown with the two bolt flange. I just need one ASAP!!

    PLEASE email me at
