Has anybody used the Edelbrock headers that advertise they will knock off 1 second on your zero to 60 time while being street legal?

What did you think?

 

Please do a search on this board. This topic comes up all the time. Edelbrock headers are a joke. They're cheap, and thats about all they have going for them. My recommendation is to get in on the SLP group purchase, or if you cant afford that, get Hooker headers.

When I first installed those headers on my 305 I noticed power increased and increased sound. But don't think for a Sec. that they will knock that much off your 0-60. What they do to get that figure is build up like a 500hp 350 with stock manifolds and run it. Then they slap on the headers and look wow a whole sec. off. I think they would be a good choice if you don't plan on doing many mods, but if in the future you plan on builing up some HP go with SLP.

You're wrong Kevin. I have been 100% happy with my Edelbrock headers, I've had them for almost 2 years now, and I have a friend who has had them for almost 3 years. Neither of ours are coated, and neither of ours are rusting. I think that the headers are one of the best bang for the buck ones you can buy. I wouldn't spend $500+ on SLPs, which do the exact same thing as the TES do. On a stock motor, the headers took .3 off my 1/4 times. The claim about them taking 1 second off your 0-60mph times are for some trucks, not our cars, but they're still a great mod.

I'm not wrong. There are countless people who have dumped Edelbrock's headers for SLP's, and not one of them regrets it. I dont know anyone who dumped SLP's headers and got Edelbrock's or anything else, other than long tubes. SLP's are the best emissions-legal header, period.

 

SLP is the best. You can find them for $375. The main beef with edelbrocks, now that the primary size fiasco is settled, is the the design of their Y pipe. The double crunched "D" Y pipe desin is looked upon very unfavorably. Flowmaster sells very nice Y connections for about $35 if you want to change it out. They have several sizes. dual 2.5" to single 3", dual 2.25" to single 3", and dual 2.5" to single 3.5". There might be more, but I haven't come across them though.

I have installed the TES headers and cat back system on my car. I did see the full second faster 0-60 time. But I have to agree with Kevin if I were going to do it all over again I would go with SLP. The TES's burn up those damn donut gaskets all the time. I'm replacing mine about every 2 months. And I've yet to find another gasket to fit in the collector other than ordering from jegs. I even tried 454 collector gaskets they were to small. Don't go cheap on headers.....

 

i had edelbrock's for a year and i HATED them. they looked like crap, and were way too small. they claim 1-5/8" but there is no way in HELL that mine were that size. i shou;d have measured them before i sold them, but i never did.

i got my SLP 1-3/4" and they are NICE. they are stainless so they look awesome, and they are just an incredible jump in quaility and craftmanship compared to the edelbrocks. i woudl reccommend SLP over edelbrock ANy day of the week.

I've got a set of TES headers on both my 87Z and my old 86 IROC (now my brother's). Been real happy with them. I'm sure SLPs are nicer but I'm cheap, and the TES spank the stock crap anyday.

Fireturd350, you can get replacement donut collector gaskets from NAPA for like $3 or something. I don't have an application (I think it's a mustang part...), I've just carried the old one down there a couple times and they were able to match it. BTW, you shouldn't have problems with those gaskets if you have the y-pipe angled/positioned correctly. Blew mine out one time originally, got it replaced and aligned right and didn't have another problem until I hit a deer carcus on the highway. It nailed the y-pipe and crushed that stupid gasket.

Don't SLPs only have like 2.25" collectors that run into the y-pipe? I thought I remembered there being something not so spectacular with their y-pipe setup.

If anybody is happy with their TES, imagine how happy they could be if they had something good.
Dan87IROC-Z of course they seem good to you at that altitude, no air to suck in means less air to push out.

Had my TES installed and Im happy with them, The only thing I have to get my AIR system reinstalled. The only bad thing is that the AIR is on them and the smell of the paint still buring off...

The sound is great and a lil more kick at WOT

for all you morons that complain about the TES headers rusting: YOU ARE SUPPOSED TO PAINT THEM!! DUH!!! they come in a coating to protect them during shipping. you need to sandblast them and paint them before you install them. i have had mine for 3 years adn they look fine. for my mostly stock 305 they work great. when i build a real motor i will obviously get the SLP. but for now untill i get out of school i have no money. if properly cared for they are great for a little 305. they are way better than the stock stuff anyway. so quit bashing them. they are great if they are installed properly on the right engine. and for all you idiots dumb enough not paint them, you get the rusty headers you deserve. and yes for a big motor they are small, but for a mild 305, like most of us have, they are the perfect combo of performance, and price. edelbrock has been engineering aftermarket parts for years, if they had a rep for makin bad parts they woulda went out of business 30 years ago.

They don't make crap but all products have compromises to them to keep costs down. SLP has less compromises in their design so it costs them more to make.

Here's the group purchase on SLP headers:
https://www.thirdgen.org/messgboard/...ML/002843.html

Edelbrock used to be good, but lately the products I've seen from them have been crap. Its like their quality control department is out to lunch. They're surviving on their name alone...

Edelbrock headers are better than stock manifolds yes, I agree there. If all you want is emissions-legal headers, they're fine.

 

yeah, and edelbrock headers arent THAT much cheaper than SLPs. i got mine (SLP) for i think $349 on special one time, and when i bought my edlebrocks they were $338. the only thing is that i had to buy gaskets and bolts for the SLPs.

yeah, the SLPs dont have as much extra crap as the edelbrocks, but thats not a big deal to me.
