hi guys, im planning on buying some headers for my iroc soon got 600 bucks in tha bank now and alot more to come this coming paycheck so i was wondering which headers where worth getting. tha edelbrock or tha slp's. i heard tha slp's are way better than anyother type of headers but there around 500 bucks or so and tha edelbrocks are like in tha high 300's. so i was wondering if it was really worth tha price diffrence.

 

deffinatly SLP..

 

The edelbrocks will rust if not coated, so that will add to the price. The SLPs flow better, but don't fit as good.

 

....The SLPs flow better, but don't fit as good.

Just goes to show you that everyone's experience is different. I've owned both brands. The Edelbrock's gave me a fit in terms of installation. And I could never get them to not touch the passenger side frame rail. This caused an unbearable vibration at idle. The SLP's slid right into place and bolted right on. And these are the 1-3/4" headers. Today, I wouldn't consider any other brand.

BTW, I don't know if this is dated material, but way back when I bought the Edelbrocks which are labeled as 1-5/8", only four tubes were. The remaining four were 1-1/2". This was their way of designing a compromise into their header that supposedly produced more torque and hp over a broader rpm range. I don't know if they still make them this way, but it's worth inquiring about.

Shouldn't this post be in the Exhaust forum????

 

SLPs are worth the trouble though plugs suck; Edelbrocks are smaller tube.

 

why is it i'm finding out stuff about these headers NOW after they've been on the car for like 3 months??

 

You should also consider the Hooker 2055's. Fit way better than the SLP's and probably make more power too.

 

Maybe I was lucky, but my SLPs gave me very little trouble with installing them. I did need to dimple the driver side primary like some others, but I didn't let that bother me too much. I probably could have corrected it the "right" way with new motor mounts, but I didn't want to add to the project at that point. Otherwise, they fit very well, and I like the fact that they are stainless.
However, they aren't cheap and SLP does try to stick it to you with the install kit and the cat adaptor pipe. I bought the install kit, but got my cat adaptor from NAPA. Just a standard 45* bend - not stainless. It fits perfectly. My plugs went in with less trouble than changing them with manifolds.
Overall, I'd do it again. Good Luck with whatever you choose.

 

1 3/4 slps..

passengers side. fit fine.

 

drivers side, before i moved the shaft/column over some

 

after moving the column/shaft over to the right.

hey it fits!!!


but needs some more help, either grinding down the shaft in that area, or oval the header tube

 

Yeah, I should have done that...

 

My 1 5/8" cleared the steering shaft no prob, but the y-pipe was a whole different matter. Looked like it was made too long and the d/side pipe didnt want to fit into the Y.

 

welll everyone that ive talked to has said to get tha slp's so i might end up doing that then. do u guys know a good place where they can instal them for me in tha Phx area.

 

hell yea.. call mike @ azautomasters 480-592-9677 tell him kris with the red iroc told u to call him. he will be the cheapest anywhere.. also.. visit www.azfba.com and becoem a member

 

thanks alot aziroc. ill make sure to say it was u that told me about it hehe. ill probley look into ordering them headers this coming friday

 

I had my edelbrocks jet jot coated and went in with few problems....I was going to get SLP, but I couldn't afford them...

 

how or where does one get them jet hot coated? it's to protect the finish and to keep them cool correct?

i got a great deal on some new edelbrocks ($275), so i'm hoping i'll see some sort of gain in performance? I seem to be quite outnumbered with all the SLP's here, but for half the price, i hope i get something outta them!?!

thanks!

 

go to jet-hot.com and email them. That how I did it. They are GREAT to deal with, I had it done about a month ago and just today in the mail, I received a Thank you card from them, a really great business to deal with, plus my headers look great, and they won't rust! I'll post pictures in a couple days

 

whoops...computer goof up, sorry

 

I paid $315 for my 1-5/8" steel Edelbrock headers, back in '94 & had them bead blasted & painted them with black VHT paint - they fit great & I have over 130K miles on them in my '92 Z with no problems.

I also have a set of the SPL 1-5/8" stainless headers on my '84 Berlinetta - they fit great, as well, & I did not have them coarted, either.

The only difference I can see is the SLPs allow much easier routing of the spark plug wires from the top - had to run the wires from the bottom with the Edelbrocks, or they'd get toasted - even with fire sleeving.

 

yah im about to order tha slp's but i also need to fix my a/c this 100 + weather is really killing me here in AZ since im originaly from cali but ill get tha slp's i guess hehe more people seeem to go towards them.
