wat power you aiming at long term? ive answered this many a time. if u want less than 250-300rwkw you want see any difference between the split or all in 1. if ur aiming more than that then the all in 1 will be better.

Go for the bellmouth, it will be much more efficient.Leave the seperate waste gate pipes for seperate waste gates.

stick with the bell mouth, your not gonna be running an external gate so no need to change dumps. the bell mouth 1 is very good for up to 300rwkw same as the split. but over 300 i would use a bell mouth anyway.

only adverse affects if u switch between bell to split, if the split pipe isnt a good quality 1 or not fitted properly, then you may find the wastegate flap to foul the dump pipe and you'll get big boost spikes cos the gate isnt opening the whole way.

U serious, I dont know about ur car but when I changed over to a split dump pipe I noticed a HUGE diff. I'd go the BOS importing SS one. Prob one of the best mods u'll ever do

Bell mouth.......100% agree with cheez from personal experience.....the split ones are a poor fit. the ones i have seen anyway

A 'well designed' split dump is superior to a bellmouth on an internal gate turbo like the stock R25 unit.

Don't go buying a cheap ass one anf you will do well out of it. A long split section is the ideal.

have to agree with u there

the bos importing split dump is an awesome mod if ur only looking for abit more than stock power levels

i found that after installing the bos split dump the car just wants to go and looks good too
