HOOKER,HEADERS BY ED

I replace ill fitting expensive brand headers with these. The flowtechs seal better, cost 1/2 as much, and look great! They went on super easy even though my 55 has modern side engine mounts, a clutch z-bar, a 605 power steering box, and power brakes...about all the options that normally cause issues with fitment. I will be buiying a set for my Chevelle this Fall! Excellent product!!

none, horrible product

flanges are to thin. hard to work with

First off I've put on a hundreds of headers and these were the worst i've ever worked with. the flanges on them are to thin and warp very easy. Would not recomend product.

Cheap, easy on when motor is out of the truck

hard to get spark plugs in rear

I have a 350 sbc i pulled out the old 305 from the truck and befor i put the motor back in i put these headers on they went on easy out side of the truck ond sounded great on the stand the only problem i had was the spark plugs in the rear of the motor the primary tubes were too close to get a socket in to change them

none

had to hit and bend tubes on both sides were hitting on steering shaft and frame

I bought these flow tech headers for my car, I fix cars for living and they were nothing but trouble to install,needed to hit and bent tubes on both sides and by the the way the car is 1967 442 as they say you get what you pay for!!

Included holes for O2 sensor and other smog stuff. Flanges etc are thick and well made.

1. Really difficult to change rear spark plugs on driver side. 2. Coating flakes off - but prob resolved with spray can of heat paint.

Engine rebuilder installed a set during engine overhaul. After 3 yrs and 40,000 miles - no leaks and work fine.

None, should have spent more money to buy a better set.

To many to list

I am a profesional mechanic and have installed many sets of headers, these are the absolute worst I have ever seen. They are poorly made, the paint was rubbed off right out of the box, had to sand, repaint and heat cure. Also they fit very poorly, welds are terrible, pipe fitment is all off, leaked at collector connection. Had to remove from car and extensivily modify to get them to seal properly.

Look nice, Nice price, Sound good, installation was not a complete hassel,

Header Bolts have to be excessivly retighten, Lost a few header bolts due to becoming loose, Collector Bolts have become brittle due to just a few warms ups and cool downs, Collector Gaskets are leaking, Bolts are too close to header pipes making the tightening and installation hard, I would also like them to consider including header rap in the box for the vehicles with ignition wires close to pipes, after 1 month after installation I already had to replace half of the ingnition wires

I installed flowtech hearders on my 94' GMC Z71 because I had a large crack in my driver side manifold. Installation was alot harder than removal. All in all it was not really a big problem. The hardest part was driving to the mufflel show to get them to put the new collectors on because I couldn't accelerate fast cause I didn't want to bend a valve

none except that they cost $800

first of all it was cheap it was only $800 just for the headers for my 1988 mustang gt, my friends said that i got ripped off but i dont know. i bought them at a garage sell in houston and they were looked like they would be good so i bought them so far they dont sound no different nor do they fell like they added power.

Drivers side was a pain. Had to bend one of the pipes in so it woulden't be in contact with the frame. Pasenger side I needed to get a smaller oil filter.
