Review on 🔥 AB Catalytic 741-46-251 - High-Performance Exhaust Pipe for Enhanced Engine Performance by Isaac Tutt

I was trying to install it on a Mazda 6 automatic transmission and none of the flanges would mate to make a good seal. There is what I would call a fin on the mid tube that does not match or touch the motor mount frame. Ground the edge only to find that none of the flanges match. The center exhaust also came too close to the engine oil drain plug, really raising doubts as to whether there was enough room to remove the drain plug. Due to time, resources and money I finally cut the broken pipe off the original exhaust and spent 4 hours cutting, bending and fitting them into pieces to weld them together. It is better to buy the original exhaust pipe from the dealer.
