Mazdaspeed downpipe/catalytic converter upgrade
- Product Review (submitted on April 3, 2018):
- This product is very nice and clean. The instructions on this website for installation support was very helpful. The only problem I faced was that the front triangle flange that connect to the back side of the turbo flange was not completely flat. It did not seal completely. It appeared as if the flange may have been warped during manufacturing during the welding process. It was an easy fix with some machining down. Otherwise a very nice fit!
