Hello Guys...
I own a F10 535i 2012
i wanted o buy Cat-less Down-pipe, i rounded it to two choices , I liked the VRSF and EvolutionRacewerks
but there is one difference between them the VRSF doesn't have Steel Flex Section in the DP , But ER has a Flex Section...
What is the use of the flex section ? and which one do you think i should buy ?
