Title: Header rattle
Post by: 425hp87chevy on October 27, 2009, 06:43:05 pm

Hey I thought i was hearing a noise in my engine and come to find out it was my headers. The tubes tubes are rattling against each other at the right rpm. I thought of tack welding the tubes together. Will this not allow proper flexibility and break them? How can i get rid of this annoying noise? Any advice appreciated

The only time mine rattled was when some bolts worked loose, and I'm using cheap, used longtubes. (of course I don't have the H.P. either) Did a weld break on the flange?  Just for giggles, what RPM?

I haven't had a chance to check the bolts or welds yet i just found it tonight but all i know id that the pipes are touching and i pry on them it goes away. And i think it's around 2000 RPM

Are they cheap painted headers? If so just tack em near the collector.

they are just a painted header but where they are long tube would tacking them near the collector stop my rattle?
