Hey guys whats up. Im hoping that this dosent tunr into a flame war with all sorts of crazy accusations and mechanical alchemy. But I just had Flowmaster American Thunder True Duals with an X Pipe put on i have a MMR intake with a high flow tube and a set of Mac headers on the way also a SCT flash tuner with a tune for my setup. So if the car has been tuned to Account for the Duals do you gain or lose HP and or TQ and if so where do you gain or lose it High or Low. Thank you for civility in advance
Oh Yeah has anybody else got and of the buzzing or other noises after they went dual I saw a TSB about this and I was wondering if anyone knew where i could get what i need to fix this i think they are called resonators or dampers, or does anyone know of a improvised way of fixing this thnaks again.
