Does the 1991 LSC Special Edition come with factory headers if so would after market headers provide any benefit?

lsc coupes are very well designed. placing "aftermarket" headers doesn't really do much but cost you money. these cars are very fast as is, think... it was after all based on the Ford gt mustang engine and tranny. performance wise, as a mark 7 owner i wouldn't change anything.
LOL performance wise?...I think you mean "economically"
AnswerIn specific, yes, the vehicle did come with factory headers as well as true dual exhaust. AnswerOK...So Im assuming that by headers you mean aftermarket...all cars have "headers" aka exhaust manifolds. Changing the exhaust manifolds is a GREAT idea to add extra horsepower and torque to your Mark. One of the weakest links on the 5.0 motor is the exhaust. The factory exhaust manifolds on the 5.0 are tiny little tubes of metal that choke your motor from breathing. If youre thinking of doing ANY kind of horsepower adding upgrades, don't start anywhere else but with new exhaust and intake components (upper and lower). 1 5/8" headers are ideal. Equal or unequal length are good, longtubes are the best but require some extensive work for the average do-it yourselfer. In my opinion start with a good catback system (mufflers, H-pipe, etc.) before you go getting involved with new headers. Just think of your motor as needing to breathe easier to make more power. The 5.0 motor is such a dog compared to what it could be...even in a Mustang...trust me, I do this for a living...these guys that posted before me just must not like fast cars =) AnswerI agree with the last post. The headers on the Marks just like the Mustangs are tiny. After market headers as long as they are larger diameter will make a difference. I owned a Mark myself. You should really upgrade the hole system but I know alot of the time people don't have $300 to drop on a new system. Headers would be a good place to start. Down the road you may want to look into getting you exhaust ports matched to the diameter ao the headers as well. They are alot smaller, but I strongly sugguest you have this done by a professional shop.hell yea after market headers will add power, look at the baby headers that came with the car.
ANSWER
I have a fully worked out 91 LSC special edition black. Leave the stock exhaust headers! They are plenty to push anything that the engine can handle. Get rid of the "4" cats and replace with 2 high flows to keep it legal. Switch to an Ford Explorer intake manifold from the junk yard (will require custom hood work to fit underneath) And put in some 1.7 roller rockers. If youre gonna go that far, MSD ignition and high power coil is recommended. I also converted to a stick shift...and i eat mustangs up all the time
