I just finished swaping the manifold on my 2000 GT, (my everyday driver). If you still have your stock FRPP manifold on your car, when it cracks and leaks coolant. DO NOT buy the Dorman manifold. IT SUCKS! I bought it because it has a lifetime warranty and the Ford did not. I have never been so disappointed in a part. It is supposed to match OEM and does not come near. I noticed the smaller opening on the runners before installing, but thought it would be ok as it supposed to match OEM. After the install, it feels like a V6. With the Ford manifold when i hit 4,000 RPM, my car would tear a**. With this Dorman, it never hits a powerband, it is a disappointment throughout the whole RPM range. This manifold will starve your motor of air. I hope this saves somebody else from getting a headache.
I will be replacing with a FRPP manifold in the future screw the no warranty.

Some research on the subject probably would have saved you the headache. People have had horrible experiences with Dorman. Hope you get it straightened out soon!

That blows. When i replaced my cracked intake with a dorman i felt no difference.
Reason? It was a stock nonpi 97 GT

Only reason anyone should get the dorman is if its a DD nonpi they only use to get from A to B with no playing.

If that is the case they'd be better off with a PI intake off craigslist. Or selling the car for a POS econobox.

Damn man, that sucks. You should have made a thread here before-hand and we would have quickly steered you away from Crapman.

Yea dude, did the swap b/c I didn't know any better, looking at the ports, the ports are smaller. Besides the similar but not congruentcy, the crappy rubber rings on the bottom of the intake gave out quite shortly after my install. But finally gave competely this year.
Sooooo, I bypassed the stock manifold and went the Performance Products way. We live and learn.

Not to mention the damn brass female threads are glued into the manifold so riding in Charlotte the damn fuel rail un-bolts itself and I lose a half of tank of gasoline going down the F**king street, so I'm stuck in 5 O'clock traffic tryingto push then bolt the fuel rail down in a gasoline soaked engine bay praying someone doesn't throw a cigarette or backfires out of there car. If I could have afford a lawyer, would have bought the company and kicked who ever installed the brass threads with glue, in the testis w/steal toed boots.

End of rant.

I thought you said you learned your lesson? You just traded in one crappy stock intake, for a crappy performance intake.

Yea sure, but my choices were limited, could have went back stock, but wanted a considered upgrade; Kennebelle was really out my price range w/dyno-tune. The Trickflow needed to much done, was not a simple bolt on. Bullet needed other mods as well. Edle Brock was my first choice but then realized it would not work with my fuel rails and upper Intake (probaly so they can make up some extra cash.)

Performance Products has done o.k. thus far, not recommended without cams though.

Ah well, at least you know it isn't going to crack on you like one of the composite ones.

Edelbrock would have killed your power you would have hated it! its best for cars with ported heads, etremely agressive cams and longtubes revving to like 7000 is the way to benefit an edelbrock

....or boost
