I thought that maybe they would just make it sound a bit more aggressive, but that was not the case. They totally changed the power output. More low end, which totally caught me by surprise, and the top end is kind of intimidating, being 2 ton and all.

Putting the cats in the manifolds is brutal for power output. The M54 left a lot on the table from the factory.

I'd imagine that a blower would feel that even more.

Yeah they completely changed the power curve. It was a bit of a surprise. The blower is most definitely running more efficiently now, than before.

I was worried, because I have used headers on other applications before, and although top end was better, I had a distaste for the rest of the band. I get caught up in the exhaust note, and forget there is risk to the power output when making changes to an established setup. Not the case here, substantial upgrade to this setup.

Hats off to Dr. Lavr! The product definitely delivered. I got them just in time too! It seems with the conflict in Europe, that they may not be available in the U.S. for at least the moment.

I wish I had got some for the N62 as well.
