Matty...sorry bud but I will probably have a hundred questions for you!!
I can run 3" on both sides which I know is useless on the ht18 but I know I will be getting a larger turbo and pump in the near future. I also have the 3" mandrel bends from the wrx ic and they will work a treat.
My question is will this be ok for the interim until
I can afford to upgrade it all?
