Flowmasters?
I have a 2002 F150 and i recently took off all my cats i had 4 also and i just put 2 new cats on so 2 less and a flowmaster out law race muffler one of the loudest mufflers they make and i set off car alarms going 15mph.
ya i sold a few of them. there a race"muffler'' and i use the term muffler loosely. there pretty much just for race cars that are racing in a division that requires a muffler. on a truck like ours they sound like a strait pipe. so dont wast your $ because strait pipes are the same sound and no where near the cost!
