Agency Power Exhaust

I am looking for a used Agency Power Exhaust for my 06 M6.

email kgdavis63@yahoo.com

I would NOT recommended Agency Power. I have seen dyno of theirs headers actually losing power.

These are the exhaust systems I would recommend for the most power and best sound:

Eisenmann
Tubi
RPI

Thanks I was actually looking for cat back only, but I will take your advice inconsideration.

Also go register on www.m6board.com

That forum is way more active and is a very helpful community with great people.

OK thanks, by the way what kind of wheels are those? I need to post some pics of my M6 just added H&R springs and spacers looks awesome.

They are the stock BMW M6 wheels style 167.

I hated the OEM gun metal finish so I had mine powder coated matte black. $90 a wheel

Wow they look awesome that is the answer to my wheel problem thanks so much.

Thanks! It really changes the look of the car IMO.

Glad I could help!

+1 on the Eisenmann. Best exhaust for our car, bar none!

Hi thanks just bought a used set of Eisenmann mufflers today. Went and talked to my mechanic, he is recommending adding an X pipe and removing the two aft cats. but not removing the resonator stating it would create too much interior noise. Are you sure you removed the resonators not the aft cats?
Thanks, Kevin
