Yeah im in two minds. I want the cat and dump and go in for a retune but I dont know what set up to go for. I think the SMB 4' Dump and 5" cat is about $1500 fitted then add the $500 for a retune. Is this the best setup or can you have another setup for cheaper. I could get a rapid systems Hi Flow intercooler kit with cold air induction for $1600. I don't know too many options.
