hi all,

just a couple things i need to know really, is the bd14 exhaust profile any different to the inlet? also, do i need to run uprated springs with one?

the reason is i've seen a bd14 exhaust for sale, i can put the grooves in the bearings myself, but need to know if anything else is different?

thanks

 

They are the same profile m8 and you dont have to run uprated springs with them, that depends on the rpm you would go for
above 7500rpm you have to go for uprated springs

 

awesome, thanks

 

dont forget it will be 180 degree out so timing will have to be done with a dti
