Well I finally got my Hooker 6907 long tubes in place! They have 1.5" primaries and 2.5" collectors.

Good news they fit great! No fitment issues at all. It took me about 6 hours with help (and a few brakes to eat as it was Memorial Day) to get them in and mounted. The last passanger side bolt took easily an hour to install itself. I used copper collector gaskets and Mr Gasket Ultraseal head to header gaskets.

Bad news, making the y-pipe was very tough. The collectors come right by the trans crossmemeber. I had it lift and go up and over, no big deal. Hooked up to my High flow cat also. The Y-pipe is 2.5" piping to a 3" collector.

Also, I have a Magnaflow 12588 installed. I had it dumped as I need to have a stud girdle installed prior to having tailpipes made...so there is some resonation by being dumped. Should easily go away when tail pipes are made.

Power gains are noticable. Torque is up and will easily spin the 275's out back for a few seconds with two full gas tanks. But I also finally got my K&N FIPK up with a home ported 70mm MAF. So now I have a killer WOT sound...but not as loud as open headers! Some emissions piping is now gone too...

Thanks for reading and ask away if you have questions!

 

Sweeet!! Glad to hear everything went well without any major snags. PICS!! NEED PICS!!
Also how does she sound???

 

I gotta waste about 20 shots on my camera, get them developed, and I will scan them and post up.

I like the sound, it isn't as loud as I thought which is great for what I am looking for. Going from the shorties to LTs there really was no sound increase, but from manifolds to shorties there was.

 

Hey, I got those pics up in my user gallery. OR go here...

That Y looks nasty. If you wanted to keep the single exhaust then a Flowmaster Y would have really helped. True duals would be better. part # FLO-Y250300A

Hitman X,

Those headers look cool. Im lookin for some long tubes right now. My true duals currently bolt up to the manifolds. Exactly how far back do those collectors go on yours? My drivers side pipe turns and crosses to the right side around the back end of the oil pan. Those pics look like they go waaaay past the oil pan, which is bad news for me. Could you clarify this any? Any thoughts on the subject? If I could make em go without having to practically put a new deal in Ill get those headers. Not sure what ill do otherwise, I dont want shorties. Any input would be greatly appreciated.

Chris

 

V10man...Well, I don't feel like spending far more cash for true duals right now...I'd need two 2.5" cats, crossover, and two mufflers. There's another $350+ in parts alone! I had a Flowmaster Y-collector but it wouldn't fit, if you have ever seen under there it is very tight with those long tubes. Besides these trucks were never designed to have these headers on them, so anything is going to have to be custom done each time via trial and error. When that anemic 302 gets tossed rest assured I will have true duals.

HD...The collectors come to about the mid of the transmission. Well all full length headers will come that far back, there is no way around that. If everything from the manifolds is new it should not cost too much more to adapt it to the long tubes. As you stated shorties don't do too much, you will have a sound increase for sure but maybe 10rwhp in the higher revs...whereas the full length will add noticable power all over. Also remember shorties and long tubes cost about the same too...

 

what kind of truck did you put the headers on. I have a 95 ford and I am about to put headers long tube on it. And I was wondering what kind of mess am I going to get myself in to.

 

They are on an '88 5.0/AOD.

Install needs a pal... bribe them with food, beer, etc for the help positioning the headers. lol You will need the help, trust me.

 

am I going to have to relocate anything like my fresh air pump or anything of that nature

 

Nope not at all. Only thing to modify is the oil dipstick, which is very easy to do.

If you have AIR injection that will have to go byebye too.

That air tube to the cat will have to be modified to keep it. I just chucked my smog stuff (kept the pump) as the important pieces did not work anyway and I passed the sniffer in Texas fine without it.

 

I thought texas didnt do the smog testing. Is that something new cause it is not in my are yet

 

area not "are"

 

Some counties don't do it, as I am a city slicker Tarrant (where I live) and Harris (where my truck lives) counties both do.

I think the ones outside of your main metro area usually do not...that is why people get their "off road cars" registed there for no sniffer inspection.
