Which company/manufactuer makes a 3" dp without having to shave/grind the block?? i'm looking foward to do a custom turbo setup, using t3/t04e 60 trim w/.63 a/r turbine for my b18b1 motor and run 3" piping all the way to universal turbo apexi n1 muffler. Btw, the piping is gonna be mandrel bent.

 

bump

 

i notice alot of ppl when ordering my 3" exhaust piping, that they pick up items to do their own custom 3" downpipe. many tell me its hard to find full 3" dp's that dont hit.. so they buy the bends and do it themselves?

just an idea..
