naa not 4inch flange, someone said that if you have a 3inch exhaust that i need a 4inch matrix..thats what i ment..does that sound about right?
and i think ill pass on the decat..id be f****d if i get caught haha.
on a side note fellas, if i were to buy a turbosmart boost tee and up the boost to 10psi would i need a boost controller to set it to 10psi or can it be done on a dyno without a boost controller?
