Combine the Active Autowerke Exhaust SECTION 1 with a pair of Hi Flow 100 cell metallic catalysts and you have part of a winning combination for your BMW E46 M3.

DESIGN AND CONCEPT:
Factory BMW exhaust SECTION 1 for BMW E46 M3. Why create an exhaust SECTION 1 when the USA version BMW factory SECTION 1 already comes from the factory as a straight through design with two separate pipes and resonators already built in on one side?
If a performance aftermarket headers was installed, how much better could one gain against the already BMW factory SECTION 1?

SOLUTION:
The BMW Factory Section 1 with RASP like sounds Active Autowerke Exhaust SECTION 1 only comes into play if the E46 M3 already has a performance header already installed. One will experience a high smell of unburnt fuel. (due to the open exhaust w/o any catalysts) and development of a RASPY like sound of which the BMW S54 engine is notorious for with the BMW Stock Section 1 when equipped. This raspy like sound is a matter of engine sound harmonics at a specific RPM range, a sort of resonance that is very loud and noticeable when the engine is revving at or above 4,000 rpm.

This is the BMW section 1 - where the RASP like noise emits from.
BMW SECTION 1 for Rasp Elimination on BMW E46 M3With the Active Autowerke Exhaust SECTION 1 installed, the BMW performance gains are about the same as running the factory section 1. However, that's impressive considering the exhaust flow is also being filtered while running through a pair of 100 cell catalysts. The power and performance is still there.

Gone is the smell of unburnt fuel. A BIG advantage.
Gone is the RASP like sound. Another BIG advantage.

Great item
I have several of these for my German Shepherd and Hound dog. While the Shepherd can still manage to get this apart it takes a lot longer than other chew toys.

Would not recommend
I bought this for my bulldog/boxer dog thinking that it was completely made of leather but it’s not. It has an inch of felt type material between two very thin leather pieces which makes it easy for her to chew on, becoming soft very quickly and then falls apart. We took it away from the dog the first day and threw it away because we didn’t want her swallowing felt type material.
