Would putting a flowmaster either super 44 or 40 series make a 1994 5.0 mustang sound good?

I find my 94 5.0 really quiet and want to make it sound better and louder, would just replacing the muffler with a flowmaster, keeping everything else stock sound good? or would something else sound better? I dont want to put a lot of money into it though|||take off your catalytic converters, run an x pipe, to super 44 flowmasters, some headers and this car will sound AMAZINGLY NICE, i love that mustang sound with a nice exhaust, i have a msutang myself and i get compliments with the sound of mine all the time. not really that expensive either if you look around.|||The FlowMasters will improve the exhaust tone. It'll give it a nice low rumble with a V8. I have them on my '66 Stang.|||Yes it will be a good investment for you. However, the 40 series are raunchy loud. It will be a significant Db increase over the stock Mufflers. Stick with 2 1/4 or you'll knock torque out of it, too.

One of the best things you can do for about $15 is to buy a box of Rocker Arm Pedestal Shims and put them under each rocker arm bridge. You should be able to get away with at least a .030 shim under each rocker arm bridge and still have sufficient preload so the rocker arm does not make noise. Torque each rocker arm pedestal back to 20-23 ft lbs. Then tug on the pushrod and make sure it doesn't rattle.(The valve will have to be completely shut and not on any opening/closing ramp of the cam when you do this.I would do one cylinder at a time and put that cylinder at or around Top Dead center at the compression stroke before you attempt to pull the rocker arms off of that cylinder.) If it does rattle, it will want a little less shim thickness. On those stock engines, I see about .060 pre load on them untouched. This of course is ridiculous. On a side note: The more pre load a Hydraulic lifter has, the more power it will cost and certainly the more it sets the lifter up for valve float, as well as the earlier in the revs float will occur. Stock, she'll scream to about a 5200 RPM shift point and have considerably more low RPM punch.



You will gain extremely noticeable power from idle and throughout. It will also clean up the idle quality, you'll find an extra 500 RPM on the top end and you will gain Gas Mileage. Other than the exhaust note with the Flowmaster, you'll gain a hell of a lot more doing this than you will from a Muffler swap. However, do a muffler swap and let it go.



I would run Royal Purple 75W90 gear oil exclusively in the rear end and in the transmission if you have a 5 Spd.



Keep a 195 degree Thermostat in it, as that keeps sludge away and condensate boiled out of the oil.
