thermal wrap

Does thermal wrap cause a tubular exhaust manifold to crack?

It's been said to cause premature cracking on tubular manifolds....

Profile says your on a 16g....just get a cast FP manifold, best bang for your buck and damn near impossible to crack

No, crappy welds, corrosion, and heat cause manifolds to crack.

Short answer: Yes. Wrap is harder on the manifold.

I'm not a fan of tubular manifolds to begin with, they just don't have the longevity and do not hold up to the heat cycling. I contemplated using wrap a while back and after a bunch of research decided against it. I've been running the Turbonetics T3 cast manifold for like 7 years now. I sent it out to Jethot to be thermally coated and its held up exceptionally well. Performs well and still looks new. It ran like $300ish but well worth it and much better than header wrap IMO.

Well im running a shearer t3 and the temps seem to get high in the engine bay but i dont want to risk it either

Then call up Carlos Tirado and have it ceramic coated.

I'm guessing the heat trapped by the exhaust wrap is different than the heat you're talking about.WTF

OP, higher temps will cause premature failure of any metal. The more metal is heated, the more brittle it becomes.

Wrap a manifold, leave it on your desk for a few years and see if it cracks. Bet it wont.

Went through two tubulars in six months. I wrap it always to help stop heat. Force Performance has not let me down yet. About $200 not as pretty but very durable.

There are other factors in over heating or high temps. Air flow to radiator, heat soaking a intercooler causing high iats. Just saying there are other factors that contribute
