    1 Top Rated 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.

      This should be a free option

      Well, the adapter fit perfectly and did what I wanted it to do, connect my Mishimoto downpipe with my Mishimoto exhaust. Personally, I think this should be an option when ordering the cat-back, either buy the 3" adapter or the one that comes with the cat-back currently, which fits the stock downpipe. Now I have a stock downpipe adapter sitting in my garage, after I paid for the 3". Also, AM doesn't show this on either the downpipe page or the cat-back page. I went to install my downpipe with my cat-back and realized I needed it with the car in the air. It's hidden in "exhaust accessories" with exhaust tips and stuff. Not intuitive.

      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.
