I got my 1 7/8 ARH stainless steel headers and Y pipe from a local vendor. They sure are nice and the fitment is excellent. These should help my LS2 breathe a bit better. I went to the ARH facility thats right here on Long Island today to pick something up from Nick the owner. Very nice guy and one hell of a BUSY shop. Anyway here are a couple of pictures below. That's a custom Y with a 4 inch outlet and fits like a glove. Quality stuff right there enjoy the pics below

ARH is as good as it gets for fitment.

Yep, there have great workmanship in their products. I have the same headers n Y pipe on my 00 TA. Dumps into a straight 4" Magnaflow n sounds Sweet ! Mine fit real nice also....

Why is the 02 sensor on the drivers side collector, on the outside? Or is that not the 02 sensor hole?

Also, why does the "Y" come off the collectors and get "pinched" down before they go into the 4" outlet section. Same with the collectors, looks liek they get smaller than the 3" outlet section before going into the section.

Our Y-pipe only will fit our headers sorry

Why is the 02 sensor on the drivers side collector, on the outside? Or is that not the 02 sensor hole?

the Y-pipe is expanded a little to go over the collectors. The Neck down in the collector area is the merge collector it creates velocity and aids in scaveging.

That merge is not nearly as restrictive as it appears from the outside. The area that looks siamesed does not pinch the 3 inch tubes all the way down the way it looks like it does. Both 3 inch tubes have full outlet into the merge section.

I dont see an issue making power thru this setup. High quality great fitting components.

i have the exact same setup on my 402 , hell i have better ground clearance than i did with the stock exhaust. Going to have to get some arh headers for the wifes gto.

Those are beautiful.


If I wasn't in California, I would seriously consider those.

Yeah, but you guys in California have medical marijuana and gay marriage that other states don't have. On balance I'd say you guys in California are better off. Headers are a small sacrifice to make for all the other benefits you receive for being a resident of "The land of the Fruits and Nuts".

Actually gay marraige was voted down and is illegal for the second time.
However all the proponents for it are protesting. It's just a matter of time before it passes anyways.

The medical marijuana does apply here, however the federal law supercedes it.

It doesn't sound like we are really better off after all. :lol:

With all the above said, I was born and raised here. I can tell you that I am not at all happy with what my home state has turned into. Our stupid crazy emissions is one of the things that I am not happy with.


With our brave new found Obamation who knows what evil lurks in our future.


JFM-jr sorry to get off of topic on your thread.

I have nothing against gay marriage. I ask why stop there? Why not do as is done in many Muslim countries and allow marriage to other species such as domestic animals. More closely to the point is I find it ironic that California allows medical marijuana, gay marriage, gives drivers license and voter registration cards to illegal aliens, but if you put headers on your Camaro they'll find an empty jail cell for you. They've got their priorities misdirected when that happens.

Priorities misdirected is the understatement of the year.

Why do you think it cost more to rent a U-haul going out of california than in ?

Why is it that a state with the 7th largest economy has a budget deficet ?

Why is it that more businesses are moving out than in ?

At the present time me and my female wife are figuring out what state to relocate to.

Sorry JFM-jr ,

Why no coil packs on your car ?

I see you have bolt on the mounting holes.

What would happen if it had a 4" collector just wrapped around the 4 pipes cut off evenly after they come together and meet?

Also, what the port on that drivers side header, is that the 02 sensor on the outside?

JFM-jr,

Can you take a picture looking into the collector like you did with the merge? Thanks.

There is a velocity spike welded right in the center of the four primaires where they converge. It's real hard to see in the pics.

ARH did the velocity spike, right?

Yes ARH does that.

Whats the port for on the outside of the drivers side collector? 02 sensor? Bung?

I thought 02 sensors are always on the insides of both collectors????

Any reason 1-inch (or maybe just 3/4") can't be cut out from where you see my black lines? Ground clearance reasons.
It wouldn't effect flow at all, would it?

Reason I ask: I look all around my Grot 1 7/8" LT's, and if this 1-inch was cut out of them I'd have alot more clearance and I would never hit the ground like I sometimes do now. Both sides of my LT's can use this cut.

We put them on the outside of the drivers side header for routing and heat issues all our f-body systems are like that. The sensor will work fine on either side

Because they would hit the floor if we made them shorter there. we rarely hear of anybody dragging our systems they tuck up very high.

I'm not following what your asking in the first sentence. And that is the O2 bung on the drivers header

How much space is between the top of the header and the floor pans on the F-Body?

I;m lowered with G2 Super Springs so any help I can get would be nice. I don't really hit alot but I'd hate to mess up some perfectly good NEW headers. If they were just 1/2" to 3/4" higher, I'd probably never hit them.

I guess what I'm proposing is to not have a venturi type velocity collector, just a straight pipe that tapers once right into the 3" "Y" pipes.

A round collector that wraps around the 4 pipes, and funnels down to 3". All brands of LT's taper down after the 4 pipes come together, then open back up to 3".

Has that ever been tested?

Couldnt be more happy with the fit of my ARH 1 7/8. I'll see if I can get some pic's this weekend. I have the ProKit and a newly Installed Iron 408 so the front sits lower than normal for now. Will be changing the shocks to AFCO double adjustable for a better drag setup

Spend the extra dough on good quality header, and a company that takes pride in their product.

Love the headers :devil:

WS6 Store ROCKS!

Those look nice. Is the 4" merge an option available to all? I'll have to look into this exhaust setup for my 2000 z/28 project.

PSJ, ther might be a PN on that but not sure if anyone would stock it. But Nick will make anything you wnat really, if you ask them.

I have had these same headers on my car for a few years now, still fit and look great!
here is some under car pics. (My I pipe in 4inch btw) The BMR trans Xmember is the lowest paint on the car, the headers have never scraped.
