From what I have heard, the SLPs are better for the all around headers. They are also about $200 more than are the TES, so its all up to you.

SLP headers for sure! The difference in quality is easy to see. And they're even on sale right now:

SlP are better quality but are they worth the difference in price? MY TES are great and seem to be made quite well. Check out my post on the results of TES headers I just installed.

 

Like mentioned above, slp's are on sale right now!!! I just ordered mine for 400 bucks. You will even save money on slp's rather than the edelbrocks because the slp's are stainless steel, and not necessary to coat.

I believe they are. SLP makes the only emissions legal 1 3/4" headers, which you'll want on a good 350 engine. Also, SLP's 1 5/8" headers are a true 1 5/8" diameter, while Edelbrocks have two 1 5/8" primaries and two 1 1/2" primaries on each side. Considering your exhaust valve is 1 1/2" in diameter, and the Edelbrock headers have weld on the inside making them even smaller, why would you want headers that are smaller than the exhaust port in your heads?? Especially on a 350 engine? Yuck!! SLP's are the only header for me. Spark plug access is easier on the SLP headers, too, as well as being stainless steel.

 

I have only good things to say about my SLP 1 3/4 ones. I had mine coated though.

what size should i get on a 350?

 

If you have a stock 350, or only plan mild mods, the 1 5/8" headers are fine. I have them on mine right now. If you're going for some major stuff like cam & heads, then get the 1 3/4" headers.

 

If I could do it again, I would get 1 3/4 instead of the 1 5/8. So, for a 350, go with the 1 3/4.

I think the fact that the SLP headers are only available with 2.25" collectors is a MAJOR drawback! I'm pretty sure the Edelbrock primaries are 2.5"

Other than that the SLP's are better but the small collector size has kept me from buying a set. I wish they made 'em with 2.5" collectors!

 

I like SLPs design over the TES, especially at the Y pipe. The SLPs use a true Y connector where as the TES looks like it was pinched together to fit in together. BTW, these photos were taken before I put in the SLPs. My uncoated TES looks rough after 5 years: www.angelfire.com/ab2/rods/images/ypipe.jpg www.angelfire.com/ab2/rods/images/pass_header.jpg

IROCZZ3 - have you tried both the Edelbrock and the SLP headers on the same car? Can you tell us if there was much of a performance difference? Just curious.

 

Try Hooker Super Comp part # 2055
50 state legal 1 5/8 well amde and can be had for $329 including shipping with no install or any other pipe to buy. SLP even on sale still totals over $500 when you tack on $40 for shipping $70 for install kit and $30 for the connector pipe.
Strip the paint and buy a $4.95 can of 1500 degree aluminum color paint and you are good to go. Its working great for me.

what about flowtech headers, are they any good?
jgr,, was the install of the hooker headers straight forward? any problems occur?

Jed- I did the swap on the same car, from the BUTT dyno it definitely pulls harder up top. Overall, I like it.

I put a new Catco cat on at the same time with the header swap. I used to run a gutted cat with the TES.

But when I took it to the track I ran 4/10ths slower and 6 mph slower in the traps but that wasn't from the headers. I'm a retard- I later found two burned plug wires that were laying on the primaries because I didn't route them correct. I disconnected my knock sensor too but that might have put me in limp home mode the whole time at the track and hurt performance too.

I recently acquired an LPE 219 cam I could use the extra exhaust flow. HTHs.

The Hookers fit great, no major problems, just a little tough on getting some of the bolts in.

I just finnished putting in my SLP 1 3/4" headers. SLP recommended the 1 3/4" for 350's and the 1 5/8" on the 305's. The only thing is that they are super tight on the driver's side. You might have to "ping" one of the tubes in to clear the steering column, or shin the motor mount up a C-hair. SLP warned me of this before purchasing. They are on sale for $350 but you need the mounting hardware and Y pipe which is anouther $80

Now that they are in - I am very glad to have stainless headers, they have plenty of room for plug wire & stuff, their hardware kit comes with everything you need including wire protectors!
