Ask a Question

Will this work with the MBRP 3" cat back race exhaust? Try to connect the Mishimoto 3" down pipe and MBRP exhaust together without the 2.25 adapter that came with the down pipe.


  • Straight from Mishimoto's website, This adapter will only fit with Mishimoto's catback exhaust, there are no other cat-back exhausts that this will apply to. This product may fit other aftermarket downpipes with a removable V-band at the end of the downpipe, however Mishimoto has not proven any other applications with similar competitor's products.

    It makes the car sound mean in my opinion

    Bought it with as well as a catback exhaust and once it was installed I could automatically tell a difference.
