MY 2003 SVT FORD LIGHTNING HAS HAD PULLEY UPGRADE AND CHIP AND INTAKE AIR UPGRADE BUT STILL HAS STOCK EXHAUST IS ALRIGHT OR SHOULD I INSTALL A SET OF FLOWMASTERS I JUST DON'T LIKE A REAL LOUD SOUND IT SEEMS TO BE RUNNING GOOD ANY SUGGESTIONS GRATEFULLY ACCEPTEDSTOCK MUFFLERS
well its your truck... so the choice is yours.. its running good so it doesnt HAVE to be done... BUT. if the exhaust gets changed the motor will breathe a lil better for that extra boost coming in and you will have more power.... and the new flowmasters arent that loud but they sound damn good..
THANKS I THINK I WILL GO WITH FLOWMASTERS CATBACK SYSTEM MADE FOR THE LIGHTNING PART#17367 YOU ARE RIGHT THE MOTOR NEEDS TO BREATH I HAVE HAD THE UPGRADES 6 PSI PULLEY DIABLO DELTA SPORT CHIP AND AIR UPGRADES THIS SHOULD ADD AT LEAST 25 MORE HORSEPOWER I WOULD THINK/
