Look at Stainless Works,
they have been making headers for the Corvettes in the ole USA for decades and use good quality stainless steel

Else compare to ARH,
LG is made outside the USA for high profit margins, lower quality, workmanship and fit.
My LG's were made by Borla for LGM. Not outside the U.S. Unless they changed since I got mine. Very good fit and quality. I got the LG Pros, not their cheaper line.

All LG headers are made outside the USA

C5 were from Mexico
C6 are from China

Most people do not even own a OBD scanner, know how to use one or what scanner is telling them and have no idea a weld(s) has cracked and sucking air in to effect what 02 sensors report

As to fit I have seen some where the flange was not even welded to primaries at the proper angle.

Just last week saw one that the front right 02 bung weld was cracked causing the PCM to see huge left/right engine fuel trims off balance and C6 Z06 owner wondering why GM warranty would not cover repairs.

For cheap labor they should sell for 25 percent of LG prices :(

Maybe now they are made in Mexico. But I got mine in '04 and they were using Borla to make their headers. All my documetation and instructions and parts list was from Borla.

I got mine in 2006 (LG Pros by Borla) and I personally inspected every inch of them, and all of the welds were perfect and even ground down on the inside of the flange to smooth out the welds. These headers and x-pipe made by Borla at the time, was a quality product ...not now with items being made in China for LG.

If I had to do it again today....ARH or Stainless Works.

Re: C5 Z06 Long tube header suggestions

I got Kooks this summer and a dyno along with it. I have run 2 DEs' and had no problems. Still running stock Z titanium mufflers since I love the sound. I did notice a more racy sound at WOT. With the dyno it did away with the 1 to 4 shift.

Re: C5 Z06 Long tube header suggestions

Newb question here. I had to pay to have LTs installed on my Cobra a few years ago due to the difficulty of access to the bolts with a stock kmember. Is installing headers on a C5 Z06 a job that can be done by yourself in regular garage w/o a lift? Also can you swap out the cats and mid pipe with leaving the stock manifolds?

I did mine by myself in my shop w/o a lift. It does take a bit of jacking & blocking up tho. Right side went in from top & left came up from bottom so the front end gotta come up a bit. Not the most fun job, but do-able & it sure beats paying shop labor.

Some brands (ARH) are easier to install than others (Kooks). You might want to consider that in your decision.

Do you have to dismount the motor and jack it up to get them on?

If you go with ARH, Dynatech or Stainless Works you do not need to jack up the motor. If you go with Kooks you will have to jack it up.

Undoing the mount bolts & jacking the engine was the easy part of the install. I have Melrose long tubes.
