RAM/Dodge 4.7L & 5.7L Hemi 2004-2008 Truck Cat Back Exhaust Kits
Make your RAM 4.7L or 5.7L sound and perform the way a Hemi should by increasing the exhaust flow and enhancing overall power. More power means you don't have to mash the go pedal as hard and as a benefit we have seen a 2-4 mile per gallon increase on the highway.
Turbo mufflers are going to have a real mellow sound, with about the same noise level as stock but a lower tone. Street flows are going to be more aggressive sounding with more growl at the tailgate and a bit more sound in the cab and guaranteed no droning.
