I hopped on edelbrocks blowout sale for those 1 3/4 stepped to 1 7/8 headers for $194!!! Just curious if anyone knows what kinda numbers these dudes put out. Ive heard good things about them. I also went with a TSP 3" ypipe and I have slp LM1..ls6 intake+P&P TB, lid.

They helped to make 521rwhp with my 418ci motor through a 4L80E, 12 bolt with 4.56's and 315/60/15 drag radials.

Do you remember what kind of gain you got JUST from those headers?

Now idea what they made on their own. Went on a 347 with ported heads/cam etc. in a 1962 chevy pick up. Found their way on my new 418. Need to get rid of them.

They were at one point selling for over $1000. When you can get kooks/arh for that price, it's no wonder the edelbrocks weren't exactly flying off the shelf. They're a nice quality header, but not even close to $1000 header imo.

They fit better than alot of Kook's I've installed. I can tell you that much. ;)

Thats music to my ears for sure! Haven't gotten around to installing mine yet. What kind of y-pipes are you guys running with these?? The 3.5" collector makes purchasing a ypipe difficult!

Edelbrock makes a ypipe for it, and i think TSP makes one as well?


Edelbrock 6571

Yea I've been trying to find one but no luck. Most likely will go with a catted tsp setup. Just wondering if I run reducers on the collectors is a good idea or not..

I think I can make more power with a bigger header. 418ci plus the bottle.

install was great..well as great as working on ls1 can be lol...big hands..i bought flowmaster reducer cones..and a TSP ORY...i ran into some issues with fitment in my garage..no sawsall or weilder...so i took it to exhaust shop..thy had to cut a few inches off my ypipe and welded everything up real nice...tucked up perfectly..sounds good minus my lm1 which sounds like butt...i noticed a big increase in power..feels like shes breathing better...i love these stepped headers

I got the Ti-tech coated for $194!! After shipping to my house in Ky, it $235. You cant beat that for a good set of long tubes. I am just waiting to get mine on too. Cant wait! They are goin on a bonestock car with an SLP airlid, mufflex ORY with flowmaster venturi reducers and hooking up to my SLP dual/dual catback. The car is also getting an LS7 clutch kit at the same time since my factory stock LS1 clutch with 109k is toast.

edelbrock store was selling them, I got mine for the same price...managed to find a free shipping promo code...but sorry guys edelbrock store is SOLD OUT...best luck is to pay people who bought them up to make a few bucks -.- ....oh and good luck with that ypipe...I found a few sites just like that claiming to sell the edelbrock 3.5" ypipe..needless to say they were out of stock and refunding my money in 2-3 buisness days >.< .... TSP's new ORY is sick, stainless steel, cheap, and awesome merge...why look any further?

Yep got mine straight from Edelbrock. I was looking at headers anyway since my bone stock SS was throwing codes for both the damn CATS. Couldnt beat the price on these...

OH, and btw, that link I put up for the ORY is sold out too. I didnt call them but I added one to cart on there site. it showed they had them. But another guy bought one and got an email saying they were sold out and his card would not be billed. I tried to help fellas, SORRY!

I have the 1 3/4"-1 7/8" x 3 1/2" stepped, merge collector headers from edelbrock on my LT1. DS header kicks out like an LS1 header and I could probably use the TSP Y-Pipe. No before after, did cam change as well from 260/264 on a 109 to a 267/272 on a 110. Changed from a standard 1 3/4" x 3" Pacesetter, I'm sure I'll see at least 20 horsepower up above 6000 rpm (half header, half cam), converter stalls to 5600

I also have these headers, and man were they EASY to install. NO FITMENT ISSUES AND ZERO MODIFICATIONS TO FIT. Best quality header I have ever seen. +1 for edelbrock. I got mine cheap as fuck too.

Anyone running these headers with the TSP ORY and a basic catback? Just wondering if that's a bad idea since the headers are mild steel and the ORY is stainless.

My full setup is the headers, into texas speed y pipe, electric cutout on intermediate pupe and a magnaflow catback. I fucking love it.

A few questions for you...

Is that setup raspy?
Are you running an off road y pipe or catted y pipe?
If ory, does it smell like unburnt fuel?
You running reducers off the headers, right?
Everything welded or clamped?

Not Raspy one bit. Its a off road ypipe... Yes I used reducers that were custom made. The magnaflow hides my mods really well with the cutout closed...but when I open it up you can hear it all. I love it. But seriously, zero rasp. Ill post up some videos later if you want. Some is welded, some is clamped. And no unburnt fuel smell...

That'd be awesome man. Thanks for taking the time to answer all my questions. I'm thinking about having my exhaust set up like this

Edelbrock LT's -> TSP ORY -> Borla Adjustable (open plate)
