Lets talk Header Choice

[Blaine]

There are quite a few LT Header choices for the GT500. But which size is better for what applications? Which brand did you go with and any problems? Sound quality?

A. 1 3/4 or 1 7/8?

B. All of them are Stainless steel, but only ONE brand comes with a Ceramic Coating. Is this really needed to keep the underhood temps down on a GT500?

ARH LT
Kooks LT
Bassani LT
Dynotech LT
SLP LT
Borla LT
JBA LT

1 7/8 is the way to go, it makes a difference in top end power once you get above 700rwhp.

Kooks aren't true LT's. Had them and swapped them our for dynatech 1 7/8.

1 7/8 AMERICAN RACING w 3INCH CATTED X . We have them in stock

 

[mustarrosa]

I have American Racing and is a good compromise for installation ease and they stand behind the product..I developed a hole at the head flange and a few clarifying questions sent out a full replacement side. I have the 3 inch size. HPP racing did the install.

Directly from American Racing when I was inquiring the same:

......."The undercarriage was not changed on the 2010 Shelby’s. Our headers are a direct fit. We can have the headers ceramic coated but it really is not necessary. There’s no under hood temp issues or corrosion problems to worry about with the 304 S/S we use. Call me when you’re ready and I’ll get you all set up. Thanks for inquiring

It appears a lot of the other companies use 409 s/s (and don't mention anywhere what type they use) which isn't as good...and necessitates the need for ceramic coating. I've read nothing but great things about the fit, installation, and quality of ARH.....which is what I'm going with for my Shelby, along with the KR axle-back. But I believe unless you're gonna mod the hell outta your Shelby, 1 3/4" is the way to go.

I am shooting for around 700-750 rwhp. 1 7/8 headers will be the better choice for me at that power lvl I believe.

No doubt.

I had SLP's on my GT and loved them, installer said they were pretty easy to work with as well.

Just about done installing 1 7/8 Dynotech's w/3" catted x-pipe.

Don't forget Stainless Works

I'm glad you all have choices now... I did my Kooks 1 3/4 before anyone else had their's built!! The kooks on a lowered car is the way to go IMO... clearance is not an issue.... Just wish I'd waited to 1 7/8....

+1 I have had my Kooks for over a year Love them with no issues :beer:

I did the install myself... :bash: Those baby's are not going anywhere.... What a PAIN!! During the first run, you could smell the skin left behind!!oke:

 

[thebull]

Don't need no stinking headers.....TT Baby!!!!!!:rolling:

 

[EX1]

I have the JBA LTs. EXCELLENT customer service on their part. They have a good reputation and are actually cheaper than a lot of the other headers without sacrificing quality.

Ahahahaha....nothing like a fresh whiff of burnt flesh!!

 

[chimazo]

Forget waterboarding, we should get information by having terrorists install LT's on a GT500. You are not kidding about skin being left behind! Several times I almost left my sanity behind, too! :cuss:

Installing LT's on jackstands completely by yourself is not for the faint of heart. I didn't even have to drop the K-frame, touch the motor mounts, or jack up the engine and it was still a huge PITA. I'll post some pics of the install if I can finish up the damn thing this weekend.

I have the 1 3/4 AR. But the look of the SWs are a work of art. That being said I don't have a work of art kind of wallet.
