Greetings,

I just purchased my e60 M5, and would like to know whether anyone has had a chance to install and run the Agency Power headers, with Cats.
Please reply with your factual findings.

Best,

Lawrence

Take a look at the thread below. It should shed some light on the subject.

Yeah see the vids of the races on page 4 of that thread and the ensuing discussion. It'll surprise you.

WoW! That thread has some interesting facts.

The E60 headers are the MAJOR restriction AND the biggest power to gain if done correctly. To get to Z06/997TT level all you really need is a de-catted header and exhaust. If you buy catted headers, you might as well keep the stock ones and send me the $4000 to my personal bank account, is the same result, money lost.

Headers are not a bad mod, actually there the best mod to these cars, of course done the right way.

P.S. I miss my tank a LOT! :Thumbdown:

AirFrcd,

I'll let you know...I bought Agency headers and will have them on my car next week sometime with a pulley and an ECU tune. Apparently they will still pass emissions, yet are catless...

I've heard the headers make a big difference, esp. with an ECU tune. I think Agency headers are the most reasonably priced at $3k. Everyone else is crazy expensive. Jerry at Eurocharged stands by them, so I took the plunge as well and I'll let you know next week what I think!
