Heat wrap Motordyne Longtube headers

ABUNAI NISMO · 02-12-2020, 12:38 AM

I just got done wrapping these headers from motordyne. I will spray them down with silicone spray tomorrow. UPDATE: 2/18/20 - I have removed the heat wrap! I have dropped the headers off at engineered applications in Vernon, CA. 2/21/20 - The headers are done! I had them ceramic coated in chrome finish. I am happy with the job done! NEXT STEP: I am going to wrap them again in heat wrap then spray them down with silicone spray to protect the wrap from dirt/oil, etc to preserve the wrap! I am so happy I did the ceramic coating after all this! UPDATE: INSTALLED 3/8/20

How's the heat in the bay feel now in comparison to stock? I'm getting my headers coated soon and curious if that'll be enough to keep my floor board from getting hot.

debating on getting these or the PPE's. Nice job!

Moisture can build up within the wrap which can cause rust over time, better to ceramic coat it

My FI LTH's are ceramic coated. They still look clean after all these years.

I did consider removing the wrap and have the headers ceramic coated. I was in a rush to get these done so I thought easiest way would be to just heat wrap. I appreciate all your comments. I have heard both pros and cons on both ways. I have watched videos of stainless steel cracking and becoming brittle from years of usage and all while being heat wrapped. I have also heard ceramic coated headers offer little to no heat dissipation but I do believe the headers were not properly ceramic coated. So, I digress that perhaps the best way it to ceramic coat then heat wrap. I have decided to not go a rush or cheaper way by all of your comments. So, I shall remove the wrap and contact local automotive shops specializing in ceramic coating. Thank you

Abunai, your build is coming along nicely, the last thing you want to do is "Rush" things. Take your time!! You will thank yourself for this in the long run. Look forward to seeing and hearing about the end results. Keep it going!

I found a company in Vernon Ca that specializes in correctly ceramic coating for exhaust headers. I set appointment for Tuesday. I’m off from work taking in the morning I’ll ask for pictures to post. I have a choice of flat silver or chrome. I think I’m going for the chrome look.. secondly, I am still very much considering to heat wrap the headers afterward too! Is this silly? Hmmm. Thanks!

Do you still have the infamous hiss/rasp with these headers?

Definitely. The headers make it more apparent.

Edit: Woops. Just realized these were the Motordyne LTH, which are one of the few I haven't actually heard. My guess is there will be hiss on decel, I haven't heard anything for the 370z that actually eliminates the hiss, but I can't say that from personal experience. Apologies.

I can definitely hear a hiss when warming up after cold start but after about 45 seconds. It slows and calms down considerably. After that...I would say there is an ever so slight hiss from the sound. Hope this helps
