Hi there guys

Stock 335i apart from JB4 BMS DCI.

Im getting on the golf tee mod but I'm also going to a sec cat delete for a bit of a louder throatier sound, gonna weld them back on when i get catless DP's.

I have a e92.

What is the diameter of the piping needed?

and I've heard the factory use 409 SS tubing? If not what would be okay to use? thanks
