anyone have true duals as a sole upgrade? If so, have you had any problems? Im looking to add the 4" true dual rineharts, but dont want to do anything else at this point....Any feedback is appreciated.
u dont need a high flow air cleaner(but it will work with exhaust for more perfomance). tuning is a big debate some say the ecm will compensate for slip ons or for full exhaust, not in my opinion,i would retune just for the heat alone not to mention the performance gains even with a stock air intake.
Do some research to get some other opinions but it is my belief (after trying them) that true duals sound awesome and kill your low end torque!!!!!! After trying them, I immediately took them back off, sold them and got a 2-1 system. So much more power!
