True with some titanium, or stainless headers. They are usually very thin walled material and don't take well to the heat being held in. Ask me how I know...:furious: Had it happen to 1 stainless, and 1 titanium header on my quads.I know some head pipes having them wrapped will make them brittle and start to crack.
If it is any consolation, I have had my commander pipes wrapped from the heads to the mufflers since day one, 1500 miles and no problems with cracking or crystalizing!Ok Thanks man.... I'll just have to fix what I screw up... I'll post it here if I do... Thanks...
Ok sounds good.... Keep us posted.... Thanks..i will take my infrared thermometer with me this weekend and see where the hot spots are at.
