Saaame. Running SSV1 headers and V1 catted sec 1, stock sec 2 and 3. Though I’m afraid that any effective solution requires modification to my extremely pricey catted sec 1 ://

I found a thread that suggested adding this so I deleted this thread since it’s already been discussed:

Link to thread? I thought that I had remembered reading somewhere that there’s a small torque and power loss using a 2:1:2 pipe like that one rather than the standard two pipe sec 2 with a small merge box?

Supersprint resonated section 2 worth it? - NA M3 Forums

https://nam3forum.com/forums/forum/main-forum/e46-2001-2006/60967-supersprint-resonated-section-2-worth-it

Hey guys, Im about to have my euro headers and oem euro cats installed but i was thinking of changing my section 2 to the supersprint one which is resonated. Is there any added benefit since the OEM section 2 is resonated as well? Will this cut down my rasp and give me a bit more power? Thanks in advance.
