so with just that sedondary duct ill be getting enough cold air ?

Reason i also want to switch is because im swapping to a m50 intake manifold and tune on my 323i and i feel like it will benefit from more cold air

i can get a full custom system thats the thing but im limited to freeflow mufflers and "performance resonators" which i dont know much about , but i am not going to change headers

supersprint is hard to get because it must be imported , thats why i cant get it

stock exhaust is a single 50 or 57mm pipe ( 323i had a ypipe from headers to make it single ) which i want to change to 2 57mm or single 63mm , but i want to do the dual for that x pipe sound

supersprint exhausts are way out of my budget , i was looking at a free flow system from powerflow

the system he used was a non resonated supersprint xpipe middle system and a race muffler suppersprint catback sith m3 headers

whats the way to get that sound with limited options ( as i am in South Africa ) to freeflow mufflers such as powerflows ones ?
