Sounds to me like quite a few people on those threads had them fit fine with no problems. It just seems to be the people that havent really done to much in depth work before and dont know how to work out problems when you run into them. Most of these problems are not serious, and some are just simply someone that hasnt done it before and got stuck on something.

I just want to say I've had the SLP dual cat 1 3/4" headers for 2 years and they've worked flawlessly. IMO they are a very high quality set of headers. Dunno what the hell 25THRSS is smoking...

 

I guess everyone else who knows about the poor fitment of the SLP's are smoking something too right? I was trying to help someone who asked for it make the right choice on what headers to get. If he wants to spend outragous amounts of money on headers that not only fit poorly, but dont make more power than the hookers, which do fit right, then by all means go for it. If you are happy with your SLP's then great, but plenty of other people aren't. Here is some info on the 2055's.

If you actually read through those posts you posted, it appears that more people have had them fit fine than not. The only thing that seems to be fairly common is hitting the steering shaft which is easily fixed by moving over the steering shaft.

Why go through all that trouble when you can buy a better set of headers for way cheaper and not have to cut up your car?

 

Whatever, I dont think anyone is going to choose their headers based on our arguement so I really see no point to this. I am done.

 

Some folks choose headers because of things like ground clearance and to avoid huge money expenditures on custom Y-pipes too .... (get yourself a T56 with the appropriate tranny crossmember and figure out a Y-pipe for long tubes that doesn't get real friendly with the pavement and get back to me....)

And Momar is right on with the collector.... It's called a merge-collector and it is designed to aid in scavenging. Lots of headers do this. From what I have seen most of us here have nothing to worry about when it comes to choking off flow - even if they are 2 1/4" .....

And it isn't always the aftermarket part manufacturer's fault when it comes to improper fitment..... Our cars are mass-produced... No two are really alike .

All that being said, I would much rather have a 1 3/4" long tube on my car (especially with the new 383 about to go in)..... And I have gone round and round with SLP in the past before too... But they have gotten better recently (IMO) and I don't let that decide what part I bolt on my car.

I agree totally with everything you just said, but where did anyone even mention anything about merge collectors? I only recall talking about the collectors on the 2055's and they are not merge collectors. Hooker claims they are that size to assure a good seal. It has nothing to do with scavenging. Lots of headers do not do this. I am only aware of 1 company that currently offers massed produced merge collectors on the market and that is dynatech. That being said, SLP headers are nice headers, but they are not the best by any means. There are plenty of shortly headers out there that are far inferior to the SLP's. The entire purpose behind shorty headers is for clearance and fitment reasons. You can have emmisions on long tubes, I have them on my LS1. It doesnt make sense to buy shorties and then turn around and have to make modifications to install them like you would long tubes. This is why the Hooker 2055's are better. They perform just as well, if not better than the SLP's and they do what shorties were meant to do in the first place; fit perfectly with no clearance issues while giving a very nice performance increase all at the same time. Why dont you just save the trouble all together if you are purely worried about performance and go with long tubes. They will out perform any shorty, but be prepared to make serious modifications to install them. Truth be told that 1 5/8 headers are ideal for any third gen ever made that isnt highly modified, and if your motor is making enough power to require the larger 1 3/4 inch primaries it makes no sense to still run 2 1/4 inch tubing, none at all.

 

You raise some good points. Having bought the 82-87 f-body install kit for use in a g-body, I simply bought it because it had the A/C bracket and a few items of use; better deal than buying the A/C bracket separate.

But really, what good are the gaskets and bolts that come with the Hookers? It's called stage 8's and doubled up Fel-Pros, paper to paper. CTandC taught me that last one. No leaks.

Well, I started off using the gaskets that came with the hooker lt's because I ordered the wrong alum gaskets. Anyway they blew after a short while. I now have had just single felpros in for quite a while with stage 8 bolts(to bad I cant really fit the locking rings on them) and havent had any leaks. I am thinking about trying to grind away a little material on the stage 8 locks so that they will fit with my larger primaries.

Ben

 

I had to file the locks down on my Stage 8 bolts so that they would fit next to some of the primaries. Never had a leak so far and I've had them for over a year.

 

Ben,

That's what I had to do on some Hookers with 1 & 5/8" primaries. Good thing I did them at a friends house w/ a bench grinder

I am talking about the SLPs with the merge-collector business, not the Hookers... There was talk about the small size of the collectors on the SLPs and I was providing the info on why that is not really a concern. Ideally the Y-pipe should open back up to 3" a bit after that merge-collector and that is where the SLPs as a kit will hinder some flow... But either way the 1 3/4" SLPs will support more power than the 1 5/8" Hookers.... And I have yet to get my hands on a 1 3/4" SLP-equipped car where they don't fit. Yes, it might have required a little inginuity at times, but c'mon.... If you're going to play the game...... etc etc. If you want ones that install themselves, shift the sacrifice to power and get the TES.... And I have to reference my comment above about our cars being mass-produced for the extreme cases with the SLP's fitment and that we are human for the cases where something is actually improperly manufactured and they won't fit at all.

Trouble? What trouble? But to answer the question: Because I am not just worried about performance.... I am looking to get the best performance I can with my combo without paying out my a$$ to have a custom Y-pipe made.... Or more accurately, have my front subframes notched AND have a custom Y-pipe made..... I'll just stick with the SLP 1 3/4" ones for now.... And yes I will be making enough power to need as much exhaust flow as I can get (383, Miniram, ZZX, ported TFS heads, etc. etc.).

The bottom line is nobody says "Well, given the choice of running a 3" Y-pipe and a 2 1/4" Y-pipe, I will go with the 2 1/4" one"..... What I am saying, is that some of us have NO choice sometimes. Whether that be purely for fitment or clearance issues or funding AND fitment or clearance issues, etc., isn't really the point... Eventually I will have 1 3/4" long tubes on my car and have them and/or the Y-pipe made to meet my needs.... But we can't all have everything the way we want it to be when we want it to be that way... Or at least I can't .

 

Anyway, I guess I will see if I can get the locks on my staqe 8 bolts to fit with some grinding in a couple of weeks when I do my head + intake swap.

Ben

 

SLP's are by far the best quality shorty style headers you can get for these cars..

 

OK I GUESS THE 2055SHOOKERS ARE THE BEST WILL THEY WORK WITH MY 84Z28 .SUMMIT SAYS THERE FOR 86 AND UP.I JUS NEED HEADERS HELP SOMEONE NEED TO ORDER TODAY?

 

Yes, the 2055's will work on your 84 Z28.
