My combo with Track Heat Intake and converters = good low AND high? The FM Delta Flows are still too loud so I want to quite it down a bit w/ converters. If I do this, I will end up with too much low end as I have a lot now with the TW street intake. Sooo...to balance it out and give me more top end will the car run faster and better with a track heat intake good to 6500 RPM especially considering the car hits a wall at 5500RPM with the street intake?? Good idea?
