BM Catalysts BM70455 vs VW 1J0 254 300 P

I made the mistake of buying this pipe assuming it would have been built to same specs. However it seams the company called BM Catalysts is making very very poor quality products and you should not consider their products.

Look at the difference between the BM Catalysts and VW front exhaust pipe. ( 1J0 254 300 P , 1J0254300 , 1J0254300 P )

First picture is the genuine VW pipe. It has a more defined curve and it fits perfectly to the car.

Below is the BM Catalysts part. 

Unfortunately BM Catalysts has very short flex piece and does not provide enough flexibility. Also the part is also missing the heat shield just after the flex piece which protects the steering axle boot from heat. Because of this, it should never be used!

When the BM Catalysts part was installed on the vehicle, it caused vibrations between 1800RPM - 1900RPM and since the VW part is installed, there is no more problems.

Below you can see how the parts fit just before catalytic converter. The left part is the BM Catalysts part which fits poorly and the pipe is in wrong position. This cause extreme pressure on the rubber bushes and stop them from working properly.

As you can see, the BM catalysts part is also built in a lazy fashion by just welding a metal pipe under the exhaust pipe. If you look at the genuine VW part, you can see that it has been built more intricately for reducing the heat transfer to the bushes.

The part on the right is the genuine VW part which fits perfectly into place. As you can see, the difference is significant and this give a large difference in how the car feels when driving.

The BM Catalysts part weights roughly 2.4 KG and the genuine VW part weights 3.7 KG. A whopping 50% more! When handling the parts, it is easy to see that genuine VW part has thicker intake manifold connection and the pipe itself feels more robust and built to last.

Below are few more comparison pictures. Unfortunately BM Catalysts exhaust front pipe was not up to the task.
