Which headers are you using?

Or you would like to put on your E60 M5 ...Feedback?

I think we all agreed to some extend that OEM tubing for equal lenght is the best, but the prime cats that rob the power away.

So, I think RPI headers is the best and it easily revert back for emission check. The power and torque is ubelievable especially on the low/mid range.

that is what Rab Dog told me over the phone while he was testing his e60 M5 after the headers install...I want to see Rd sport, Evosport and and other manufacturers take on the equal length and compared to their headers ...

Here is my take regarding torque in low/mid.
1st) RPI headers
2nd) SS headers
3rd) Evosports headers (actually lost some at mid compared to stock)

RDSport race version still unknown, but according to Andrew Bynum, he wasn't that impressed with RD headers sport version.:cool:
