Hey Guys,

I have gotten ahold of ARH in regards to buying some stepped headers. I have asked them whether or not they will be having a GP for the C4, and my feeling is they are not going too after reading there reply.

I understand that these headers are not for everyone and they are a little pricey compared to other companies, but generally you pay for what you get.

That being said. "If" I can get some solid numbers in regards to guys wanting to buy some then "maybe" we will get a discount.

I will "hopefully" be able to pull the plug sometime early in the new year.

This is a general post, and if anyone has tryed there headers then let me know your comments.

My 421 has Hooker 1 3/4, and I am very curious to see what gains with the ARH headers. I know Will picked up .15 at the track which is "around" 20rwhp?

Maybe this will get the bigger stroker guys thinking about upgrading as well. The ARH product does look like good quality, but in saying that I only know two C4 guys on this forum who have them on there car, or two that have typed about them, and both have been impressed.

Not alot of people out there that can justify the cost/hp with their combos. Take off those heads and sell them and pay the difference for the 215 or 225 or 235 head AFR makes and you will get a WAY bigger bang for the buck

Exotic muscle has been making them for years too. Blinking an eye can cost you .15 from your et. MPH is a way better indicator of wether the car picked up at the track. There are better ways than 1/4mile to register the gains.

 

Thanks for your concerns Mikey.

The gameplan has pretty much been set out depending on the outcome of the exhaust mods.

Take care!

 

I race pretty much every week during the race season at Infineon. I make an average of 150 runs a year. I record all my runs and log each and every one of them in a log book including 60'et, 330'et. 660'et and mph, 1000'et and mph, 1320'et and mph. Along with the times and speeds, I make notation of the DA and wind conditions. I think I am well qualified to back up a claim of an et improvement when I make it. We're not talking about a couple of runs. I've had these headers on since January and have logged about 120 runs on them. Mph improvement is about 1.2 mph. Blinking an eye will cost you .15 from your reaction time but has nothing to do with et. I leave my gear selector on drive and the computer and car does the rest. The clock doesn't start until the tires break the beam. Willie

 

Not much traffic but thats more then fine. I did get 2 pm`s from guys whom are very interested. One has a 421, and the other a 396.

Take care!

 

10 years of drag racing with my Hooker Headers. Plan on upgrading to the ARH Headers this winter.

 

I have thought of upgrading headers in search of more power but I am not in you guy's power category.
Guess I need to do some searching.

 

383 vett I hear ya on the accuracy of your claims I don't doubt it if thats how many runs you have in and you document details like that.

More often than not people rarely hit the track and there are SO many variables that can affect the e.t from one mod to another especially with an m6.

 

I question whether I need the stepped ones at my power level.I have been thinking about a straight 1 3/4 though as my power numbers are with 1 5/8 Stainless Works headers,no cats,x-pipe,Corsa mufflers,and 2.5 pipe.

I now have bullet cats,and the complete Corsa system with no x-pipe

I may not be makingthose numbers now but at least I can drive it without going deaf.

I will be keeping the 2.5 Corsa exhaust for my eardrums sake so I wonder if the larger header would justify the cost when I will be bottlenecking it anyway.

I have been thinking of a different cam also but that is another thread......

 

This member has put the stepped headers on his close to stock LT-1. He sent me a pm stating that he hasnt lost any bottom end, but it screams up top. Maybe contact him with any question. He did a detailed thread of the install.

SOmething is VERY wrong with that bit of info. Thanks for the early laugh for the day Im off to a good start

 

you do not need 1.-7/8 or 1-3/4 in header on a stock or mild 350, period.
Like carbs many run too big a header. Bigger is not always better...

Rick quit reading the web and get some track (not dyno) results before you start changing too many things. You dont even know quite what you got just yet.


To offer a suggestion
-your exhaust mods will help
-This winter put the ZF and the gears in
-Get a sticky tire then hit the track in the spring.

Might just love it the way it is

 

This is what he says. I dont have a clue nor would it make me buy a set....

 

I have a 1 3/4" kit sitting in my garage waiting to be installed. When I ordered these I talked to Nick about the stepped version and he said unless you're spinning the motor over 6K on a regular basis they are not necessary.

 

That's not what she said...

 

It is a big $$$ investment but nothing is cheap here anyway.I would think the 1 3/4 would be good enough for me.
It's a damn shame I can do a cam swap cheaper than a set of headers.lol.I miss the old days.

 

Those look too nice to hide under a hood. Leave them in the garage or even in the living room.

 

Ronny the ZF and 3.45's are going in when the snow melts....

The car will be a terror in 1st and 2nd with those along with some exhaust changes, and I love right now.

Things take time man.....

 

Let's narrow the list of buyers for the stepped hearders:
1). If you have an intimate relationship with you C4--Your dial-in is with permanent letters on the window, its intimate. Auto/M6 no difference.
2). Spend alot of time at the drag strip.
3). Hit the rev limiter at 6500+ RPM most times driving the car.
4). Car puts out 500+HP/TQ
5). .15 ET is a major upgrade at this stage.

If this doesn't fit, the 1 3/4 ARH headers might be the way to go.

 

Maybe one of ARH's authorized dealers/vendors could host the group buy like last time when blackharleyman did his.

I got my headers and system during that group buy. They are not for everyone - but for those that want and can afford the best, I agree that they are nice product worth every cent.
Will
