Have you opened up your 650l's stock header?

Has anyone pulled the header on their 650l and ground away the excess welds and if so did it make a decent improvement?


Yes. No.

The weld looked like it would be pretty restrictive and it LOOKED a lot better after I ground it down. I had high hopes. I couldn't feel any change in performance after the mod.


Dont waste your time, just pony up the $ and get an xrs only or FMF header, or good luck finding a White bros. Then you will notice an improvement, where in the rpm range depends on which one you choose!

Thats gonna have to wait then, new edelbrock carb is the next purchase. But thanks for saving me from time wasted.:lol:
