clogged cats?
I still have my original exhaust on my car and I'm pretty sure my cats are clogged...all 4 of them. By getting a full exhaust or just getting an O/R H-pipe get my times for the 1/4 mile down? By the way I ran a 15.5. I've been trying to think of reasons my car isn't running faster which I know it should. Any information would help. Thanks

RE: clogged cats?
slow times could be a lot of things. traction is a big one. i get bad times right now cause when i hit the gas, the rear slides all over the place. if the car is mechanically sound, id say its traction. try a tune up and see how your times change
as far as your cats being clogged, no. they are full of honey comb but thats how they are made. yes getting a full exhaust or even just the o/r h will help

RE: clogged cats?
I wouldnt expect your car to go much faster than that if its stock. Depends what kinda rear end gears you have.
Also, I did full exhaust on my car, and its not THAT big of a difference. Stock LX heads are crap, so you can do all the intake and exhaust you want, but the real weak point is the heads.
Oh, didnt see you had a GT. Change your rear end gears for some real time improvements.

RE: clogged cats?
there's no difference in the heads on 5.0's from the same model year in LX, GT, or Vert.
Ford had an emissions recall of the H-pipes on my '88, so you might be able to get a new one from Ford under this recall if it also applied to the '87 model years although it might be hard to find new ones for a model that old. they didn't send out letters on it, just changed out the pipe when my car was in one time for a tranny drain and filter change. if you don't need the cats to pass a test, I would say just get an off road H-pipe, you will like it!
btw, I running 13.50's with those crappy stock heads! LOL they can't be but so bad now can they?

RE: clogged cats?
you know what I say? SCREW CATS!!!!!! u dont need em. you do when it comes to inspections but i day ists worth ur $ to bus an h/x pipe w/o cats and become "best" friends with ur local inspector!!! hahaha. just think about it, ud gain a good 20-25 hp without the stupid cats and its gonna be loud and beautiful soundin- youll be amazed!!! if you want to be legal when inspection time comes around, put old h/x pipe back on-if you fix ur problem or simply buy a very cheap h/x pipe with either 2 or 4 cats- u can probably find one for $150 WITH CATS CHEPEST. thats not that bad though.
