:help:My son wants to buy a non-resinator TruBenz catback system. Looking for suggetions please. He definitly wants the Flowmaster mufflers but we're not sure if we should get the 2.5, 3.0 alum. or just get the 3.0 SS system:shrug:? In the alum is 2.5 good enough or is 3.0 that much better? Is the alum kit not worth buying and just go with SS? Please help as I'm new to these SVTs I'm in to Mustangs so I'm trying to learn as I go with these Thanx Scott.... also you can email me at ssstang67@aol.com
