I installed a Flowmaster 50 series on my 2000 5.4 and found that it was too loud.I'm thinking about replacing it with a delta flow 50 series, has anyone had any experiences with the delta flow, and is there any performance increase between the standard 50 and the delta flow? Is there any price differences between the two? Thanks

 

If you want to go away from being too loud the only way is one of the next 2 ideals. The first is to buy a flowmaster 70 series which is the quietest flowmaster you can buy. The second is to put back on the stock muffler, move it toward the engine 8" have a "Y" welded right behind the muffler then have duals put on with 3 1/2" or 4" Cannons 20" to 24" long for your exhaust tips. The second one is what I did & it sounds good , just like a GT Mustang from factory...........Lariat#1
