Are Their Any Reasonable Priced, Good Quality, LTH?

[DougS550]

304/316 Stainless is a premium due to Operation Warp Speed. The shortages are across the globe. I'm not sure the tubing prices will ever return to pre-pandemic levels. $20.00 to $35.00 per foot is the current price point for 304/316 .065 wall. Most all aftermarket exhaust companies are using 18 ga. .049 wall.
Just unbent tubing alone @ 33" per primary for a V8 could be costing the header manufacturer $400 to possibly $550 ( that's not including material for the tail extensions before and after CNC bending)
Add bending, prepping, flanges, collectors, fixturing, welding, consumables, wages, etc. and poof there's a grand easy.

LOL, did you think I meant LTH the manufacture of headers? , I acronym and used LTH but as a generic acronym for long tube headers in general. Yes, I want high quality and a heavy gauge wall thickness to help prevent false knock.

Man LTH are ridiculously overpriced for some bent exhaust tubing. Are their any comparable manufactures for LTH which are in the same quality class as Kooks and other high priced LTH. Also want a High Wall Thickness of tubing due to thin walled tubing can and will cause false Knocks. Thanks

2M Fabrications is the most cost effective I’ve seen.

Thank you for your help

There is a set of 2m headers in the classifieds, free shipping.

Thanks. Do you run these or do you know anyone who has installed them?

Yes. I have a set of LTH long tubes on my 2016 GT350 with the eCOF high flow cats. They have a "titan" grey finish to minimize discoloration. Very high quality! I had two different vendors sets of "free flowing" mid pipes, but got tired of the smell. Yes, the cost versus gained horsepower was much lower with those pipes at the expense of constant smell.

$1474.00 Is not reasonable in my book.

Long tubes are so much more expensive than years ago. I wanted to set my car up for any direction I choose in the future.

I understood your acronym.
There’s nothing really over priced with quality built 304 SS headers and current raw material and labor pricing.
.065+ & high quality = Custom built.

Why would a set of quality built .065 or .049 wall headers create false knock if all the primary’s are kept apart from contacting each other to mitigate vibration ? This is where KOOKS shine in the quality department and primary tube to tube air gap spacing is a priority.

$20.00 to $35.00 per foot is the current price point for 304/316 .065 wall.

That is the retail price. Order 10,000 feet and see what you pay.

.049 is not thick wall. False knock is from the thin wall tube ringing.

.065 isn’t thick wall either. So the question becomes at what wall thickness does exhaust pulse ring not trigger knock sensors ?

Yes my M6G forum shoot from the hip price per foot is closer to a good distributor cutting a fair price to a hygienic tubing installer. I know a few that sell RathGibson, United or even Plymouth and some offshore tube and even at 10,000 feet it’s not what you think, trying to get a few hundred feet is an industry challenge for well over a year.

I was in the pipe making business but have been out for several years. .500 is thick wall

When I made headers I used 14 ga. seamless tubing. It was the best of all worlds. Light enough to save a pound or 2 and thick enough to be quiet and last.

The current price points for headers are in the .083 seamless territory. This was true even before covid.

I have not done any testing for false knock on the coyote but personally will not buy any thinner than .065. Slim pickings for sure.

Pipe and tube business or just pipe ? OWS put the hurt on all SS and SS sheet related products. This is why CORSA, SW etc. have in bold they have production delays.


This .065 or .049 wall knock has my attention. So off the cuff Hooker Blackhearts are 18 ga. (.049 wall)

Pipe and casing. Mostly J55 and P110. 8 and 16 inch mills.

Absolutely, I have read where racers with cheaper thin walled tubing was giving them false knock. I can definitely see that with todays advanced electronic monitoring systems which can pick up different levels of harmonics.

Thanks. Do you know know how the quality is and wall thickness? And are people installing them without issues or modifications etc. Thank you for your help.

I just posted I will look at them. Thanks.
