Ok guys I am new to this so need some help. I know I need a tuner. I am going with Dobec 3 or 3.5? Which one? I just want to plug and play. As for exhaust I want a deep sound. I love the look of the new rjwc duals but are they worth $900? I like the Big Gun EXO. What gives me a non annoying deep sound. I have a 13 1000 Outy XT. Also want it to last so not really looking for a cheap slip on. Thanks guys!
