i know this will have been asked many times before but which downpipe should i get i currently have a my99 with a magnex back box and straight through centre also i have a k&n induction kit (thinking of swapping to a panel filter) and an apexi s-afc2 which i use as a knocklink more than anything else and i'm thinking of getting a dawes device also do i need to do anything to the fueling after fitting a downpipe

cheers steve

 

open neck or twin dump, jury is out, not HKS. Personally I'd go with open neck with splitter, perhaps there is a twin dump about with splitter up to back of blower, but if not then deffo open neck with splitter.

 

I have a MY99 with K&N induction kit, TSL group N back box, straight through cetre and recently fitted a maxnex twin dump down pipe.
Which ever one you choose get it done sooner rather than later.

I was thinking along the same lines for a sti5 type r, then thought would it might be worth getting a hi flow cat downpipe eg TSL`s . anyone know what they are like?
