Which LT Headers to get?

[anotherneon]

I'm thinking about going with the SW with the high flow cats. I don't want to shatter windows when I cold crank it.

Go ARH, trust me!

The SW system had me concerned because there were ~2 guys that were selling there cat back system already. NO where near enough to say there is an actual issue, but I have heard nothing but good things about the ARH system. Of course I'm all for others not have the exact same exhaust as me so, you should get SW, lol

Guys that sold cat backs (which have nothing to do with headers) because they thought their dyno numbers were low. MFG were initially reporting gains of 10-15hp with a catback.

Anyone with reasonable sense knows and we said, a catback will never be worth more than a couple hp.

Other catbacks were purchased and dyno'd with the same results and an apology post was even put up, do a search. We personally dyno'd the catback to show the same gains as all the other brands.

That's the problem with the internet, someone types something up, and it's there forever whether its factual or not.

That said, headers and catbacks have nothing to do with each other. I sell a lot of ARH, Kooks, and SW. All 3 brands are usa made 304 stainless. All 3 are great brands. SW is our goto brand, but, if anyone said anything about the other 3, I would say the same thing.

Our best ET on the facory connect SW setup in our daily driven 2011 is an 8.74@159 mph.

The reason we sell more SW is because of 1) Price 2) The modular system.

The sw system has modular cats, meaning, if you swap from catted to non catted, you simply need 2 cat delete pypes that run about $30. And vs versa, if you go from non catted to catted, you only have to slip in the cats. There is no need to buy and entirely new midpipe.

We made 1079 rwhp through the headers with the factory connection clamp. I think they are a pretty nice piece.!

That said.
YOU CANT GO WRONG WITH ANY OF THE THREE!

That pass was almost 3900lbs, full weight daily driver!

I followed the SW catback thread and agree with you about a catback gaining/losing power. However; I was strictly speaking about SW headers and I know for a fact that SW makes less power on a similarly equipped car. There is a reason they are a supplier for Cobra Jet, COPO, and ACR.

Again, not true. You cannot compare 2 different cars, on 2 different days.

The only way to say that would be to dyno a car, install one set of headers, redyno, and then install another set of headers and redyno.

If that hasn't been done then you cannot say that. It is false information.

If the mfgs wanted to supply the headers, we would be happy to do a before and after.

With a 3 man crew, we can have cars on and off the dyno and redynoing with header swaps in under 4 hours.

Your right but 20-30whp is pretty substantial. I am getting a set of ARH would you like to use my car as a test mule?

Can anyone point to a SW car that's made north of 440rwhp on a dyno with just intake and tune? ARH and Kooks have shop cars and customer cars that have hit that number and then some. I've yet to see anyone brag about the HP their SW car made.

I know a lot of vendors will say that you can't compare the two, but when two separate manufacturers have made 450rwhp on several different cars using a Dynojet and not one SW car has, wouldn't you question it?

guy posted a 443 or so dyno last week

I guess 8 second et's and nearly 1100 rwhp aren't enough to show that a product performs well.

The headers are the same header....

regardless. same car same dyno, same day back to back is the only way to compare

Whos to say that a Kooks car wouldn't have made 1150? You're always going to defend SW, I get it. Somone has to.

Then why not put a set of ARH on your 8 sec car and see if you can pick up a higher trap or shave a few 10ths off? Do you have a link to this dyno with the 443 or so?

You're running SW headers, right? Apologies if i'm mistaken. What were your dyno results again?

I am. And for the record, the sound is glorious. I couldn't get the car over ~420rwhp no matter what we did. Different gas, cats, no cats, it didn't matter. Over 80 miles on the dyno over about a week. I'm not saying that SW is a bad system. I'm saying that if you're going for maximum power, ARH or Kooks is probably the way to go unless you're doing FI, which I am. My car did 390rwhp stock on three runs.

The same tune and intake on the shop car but with ARH LTs and a custom X-pipe into the factory mufflers made 450rwhp. That car made ~375rwhp stock.

Correlation does not equal causation. But that's the facts. Beefcake will be here to destroy my results shortly.

lol,

all I'm saying like previous year coyotes, the factory headers work well. the only way I feel comfortable providing results on one brand vs another is if the same car is dyno'd back to back with a swap in parts.

that just is the only way to do it IMO and provide a 100% factual answer.

If ARH sends me a set, I'd be happy to do a before and after for real comparison and compare real results

We sell em all, and love em all and am not afraid to post results, if the ARH would make more, we'd post it.

I saw this video and maybe I am out of line, so someone correct me if im wrong. But looking at this video it seems as if there is a flow problem or an exhaust leak as you can only see exhaust coming from 1 tail pipe..

At the dyno now.

Quick graph, will post more numbers when finalized.

Full ARH setup without Cats.
