Will there be any clearance issues with your blankets on the up pipes and the downpipe? I am getting tow flow up pipes from Profab
Typically not. There have been instances in the past with different combos that have had clearance issues but it's uncommon. The blankets will compress to just over 1/8" in tight spaces.
Levi are you still making blankets? I've been seeing some stainless or inconel ones too what are your thoughts on them?
Hit him up directly or we are a dealer for his products as well.
You won't be disappointed that's for sure.
Had him make me some manifold and up pipes blankets. They are nice.
Yep! Still making blankets! It'll be 18 years in September.
Duramax specific? Or just stainless/Inconel heat shields in general?
I think I bought my up pipe blanks from you 15 years ago or so. I think they're still in pretty good shape. You must not be on the planned obsolescence program.Yep! Still making blankets! It'll be 18 years in September.
It would be for a duramax, but general informationis fine. I'm just kind of curious about the pros and cons I really can't find a lot of information. It sounds like blankets contain the heat better. But they hold moisture and oil increasing the risk of parts rusting out and fire. They say they have a shorter life expectancy too, but yours have been amazing as far as I'm concerned. The other heat Shields Don't necessarily seem to be better other than somehow they don't trap moisture or oil. They're more of a lifetime product....
Cool! It's always interesting to hear some of the longer use cases on the blankets I've made over the years. $75 for 15 years of use so far isn't too bad at all. Probably should have left a loose seam that could have got you coming back a little sooner.
99% of the parts you're covering on a diesel are thick castings, (manifolds, turbine housings, etc.) The stuff that isn't, hotpipes, up-pipes, etc. generally doesn't see much in the way of moisture due to their location in the engine bay. So my question is, how big of a concern is corrosion or the catastrophic hot oil spray scenario? Not usually enough to offset the premium price for Inconel/Stainless shields in most of the cases I've worked with.
Each situation is different though, I generally wouldn't expect an Inconel/Stainless heat shield to outperform a thick blanket in terms of heat control, as most I've seen don't contain a dense insulation layer but the benefit of corrosion and oil concern may be worth the trade-off in certain instances.
I can only really share what I've seen over the past 17 years and corrosion hasn't been something reported back with any frequency, especially in the diesel community.
If your blankets have lasted 15 years so far, how much more of a lifetime do you want or really need in a product and would it really be worth the additional moolah? A lot of this aerospace material stuff is just solid marketing without the benefit in my experience.
Excellent points and that is kind of the road I was going down. The concern of corrosion comes mostly from my experience with heater wrap on my downpipe. It was heavily pitted even after only ~5years even with it painted with high temp paint that I've had good luck with not failing (uncovered). I'm installing a HSP twin kit on my LBZ so finding replacement parts isn't going to happen and plan on keeping the truck forever. So I'm just trying to figure out how big a rabbit hole I wanna go down to make this thing last. Luckily I've never had a problem with oil/fuel leaks on my truck. Who knows how long I can continue that streak...Cool!

And I'll probably end up buying some new up pipe blankets. I'm going with larger pipes and I have a feeling mine are probably not in such great shape anymore. When I installed them the last time I wrapped them backwards and they're smashed in between the up pipe and the block. I have a feeling they might have some holes in them now.....
