I’m trying to get some temperature readings on stock exhaust manifolds and headers from other guys. I recently installed Belanger headers and had them coated with Swain tech white lighting exhaust coating. On a spirited street ride I had temp readings of 390 degrees F, on a 20 minute track sessions I’m getting readings as high as 640 degrees(readings taken on the header close to the connection to the block). I’m less than impressed with the Swain Tech coatings ,I have reached out to them a couple of times on the problem and have gotten no response. I was planning on wrapping the headers has anyone wrapped them in place or should I bite the bullet and remove the headers and wrap them? Appreciate all help
Here is the link to my original post on the header heat shielding https://driveviper.com/forums/thread...ng-for-headers

Thanks
