This 2008 Mazda 3 with 2.0L engine has a 1 piece exhaust manifold, catalytic converter, flex pipe and flange. I tried buying a universal flex pipe from the local auto parts store but couldn't find the right length and also would have had to weld the old pipe (flange end) and new flex pipe at an angle - not for beginners like me.
The full replacement part was over $1000 and needlessly replaces the exhaust manifold and cat. In addition, you could damage the old O2 sensor during removal and exhaust manifolds can be difficult to remove.
Muffler Express offers a solution for the 2.0 and 2.3L that doesn't require welding or removal of the exhaust manifold. This video shows the process of installing the unit while saving the original oxygen (O2) sensor. It is a DIY job for sure.
part number:
00-2-0079.0 is for the 06-10 mazda 5 2.3L & 04-09 mazda 3 2.0L and 2.3L
