Was looking for more info because either end of this year or next year I am going to go with more aggressive mods..
RR intake stage 2
RR Catted DPs
and JB3..
and maybe a quad exhaust.. so if I can leave them on during servicing id be happy cuz the DPs and exhaust would be a hassle to remove and put back on and not to say $$$ tooo..
