Exhaust Wrap????

[Demoralizer]

Guy's, I need your help!!

What are the pros vs. cons to putting heat wrap on the entire exhaust system?

I just bought a TB MBRP 4" exhaust in 409SS with muff delete and cat delete. I got a smokin' deal on a 5" RBP black tip, so I want to wrap the entire exhaust in black heat wrap vise painting the exhaust with high temp paint that's just gonna flake off. I plan to do the Turbo down pipe in header wrap (2000deg constant, 3000deg max) and plan to go with standard black wrap (1200deg constant, 2000deg max) from the cat delete pipe back.

Does anyone not recommend this for a diesel application ('05 Crew Cab, 6.0L), and if you do recommend or not please include the reason why/why not. Really not looking for personal opinions (no offense) if you think it will look good or not, cause I think it will look awesome...but want feedback on if it will cause damage or performance loss for any reason.

Thanks in advance for any responses!! BTW, it's the first mod, other than the EDGE Insight I installed last week and ZooDad I plan to do next week.

Morning BUMP....anyone??

It will raise your egt's. Unwrapped exhaust allows the exhaust tubing to breath and disipate heat. Allowing you to have lower egt's.

If you wrap it you will hold that heat in, result will be higher egt's faster then unwrapped exhaust.

Bottom line the results are not worth the cost.

I use exhaust wrap on alot of my stuff. Here are the pros and cons.

It will rust and degrade the metal. If you have a SS system it won't hurt it but regular steel gets eaten up quick. On gas engines it will lower your egt's. Not sure about diesel. It will increase the scavenging effect. Without altered jetting it will not yield a performance gain. IN fact it often reduces power until your engine is tuned for it. Then you make bigger numbers and get better gas milage. Usually on a car or turck you wrap the turbo and the headers. I've never seen anyone wrap the whole exhaust.

That's a lot of time and exhaust wrap...

Gas engines like to keep the heat in. That is the reason to wrap the headers and turbo on them.

On a diesel you get the reverse effect.

I've thought about wrapping just the down pipe where its close to the cab but not sure about it yet.

[cartmanea]

Wrapping the up-pipes will help the turbo spool quicker because the exhaust gas will stay hot and at higher pressure/volume until it reaches the turbo. After the turbo, you want it to cool down, so I would not wrap anything after the turbo.

Wow, wasn't expecting it to cause higher EGTs as the wrap is supposed to help expel exhaust gases faster...but what you're saying makes sense that it would act as an insulator. Do EGTs really matter that far down the exhaust system, say from the back of the turbo down tube back? Has anyone tested this with a pyro to see?? Anymore feedback from others would be helpful....thx!

con..it would cost so much money to wrap 20+ ft in exhaust wrap for no reason imo..just paint it with the high temp black. my buddy did that before mbrp came out with their black exhaust they have now
