Headers

[cobraboss]

Was wandering header size 1 3/4 or 1 7/8 for a N/A Coyote?

I think there are 1⅝ and 2" also

Kooks are 1 3/4 or 1 7/8.

 

[PaleRider]

On line calculator says 1.90" so I would assume 1⅞" is best.

High RPM N/A= 1 7/8

Kooks are 1 3/4 or 1 7/8.

Are kooks truly a LT header?? I thought they were mid length and shorties. Im going with ARH. I know they are LT headers. Correct if I'm wrong...

 

[PaleRider]

Kooks said they were true LT

 

[Cyclerick]

Ditto. If you're looking for higher HP, then you'll be at high RPM, then 1 7/8

Tks. for all the input. My tuner says 13/4 unless I run a blower. Went with 1 3/4.

u did good with 1 3/4. i have stainless 1 7/8 and it is tight from frame all way down to the A arm mount .i had to grind down that lip on half of it to not let it touch.nice headers and great sound but big tubes.

Okay, so I understand this right, You installed the Kook's 1⅞ and it was a tight fit; You had to grind some of the lip off the A-arm so it would not touch it? What year is your Stang?

2012, long tube,kooks are mid-lenght

 

[PaleRider]

Oh okay.
Kooks are mid-length for 2012 I guess. I have Kooks LT headers on my 03 and I am to understand that Kooks are offering LT for the 2015.
