hey im new to this site and i am after some help on getting a exhaust system and tune on my vz S storm ute. I spoke to castle hill exhaust and they reccomened in getting pacemaker extractors with twin stainless cats that goes back into twin 2 1/4 inch then into single 2 1/2 inch. They priced me $1400 pacemaker extractors and twin stainless cats and there back $500. And the price for the custom dyno tune $880. What do you guys think about the price and that system?
