Header Got Bent!
Looks like I hit something pretty hard on the road and now I got this big *** dent on the pass side header. I was thinking the only way to fix it would be to weld a small bar or something to it, heat it up red hot and then pull it out. The header is aluminized steel with a ceramic coating. Anyone have an idea on how to repair this? Thnx guys.

You will destroy the coating trying to heat it hot enough to allow pulling the dents out. If you are not concerned about the coating, you can always spray it with high temp paint after repairing. On off road vehicles I’ve used a sheet metal screw on the end of a slide hammer to pull exhaust dents. A hole is drilled for the slide hammer; the pipe is heated and then pulled using the slide hammer. Not pretty but it works. It might take more then one hole. The small hole is welded shut after the dent pull. Not something I would really like to do on my own Vette though.

I don't know if this would work or not being so far inside, but the guys who had the old tpi manifold with dings in them would push big ball bearings through them. In other words, you have to have some big *****!

I would try a slide hammer and a stud welder. May have to grinf off the coating. Harbour freight has them pretty cheap and for use here and there only, the one I have works well.

I know it would be more expensive, but really were dealing with your "baby" here. Why don't you send the pictures to the manufacturer, & see what their suggestion is in regards to a fix. They might even offer you an excellent deal to fix or replace the one header. Just a thought. Good luck.

Yes. Texas Speed. Theyre aluminized steel with a ceramic coating. After this Im planning to lay a nice coat of ceramic high heat silver paint. Its just a little surface rust.

one of my buds has a 408 tfs 235s nitrous. blah blah. he managed to hit a ladder on the hwy at 80 mph. dinged the SHT out of his kooks. nice ding. car still runs fine. last time he went to the track he was effing with the tune on the way there. ended up dropping a plug with no spares.. car still went 10.80 on 7 cylinders motor only. so i dont think that ding is really all that big of a deal.
what im saying is, even though it looks kind of nasty, i really dont think you are going to notice much change. by heating it up and pulling on it, its still gonna be effed up and out of round. according to the photos, if those were mine, id just run em how they are.

I think if you remove the header, clamp it in a vise in soft jaws, apply some heat to the area, and drive a large steel ball through, you'll be good. But, you need to have a way to draw the ball back out, 'cause I don't think it'll pass through at the other end.

So unless you crush it real bad it will still flow the same volume with a dent.
I'd leave it alone unless your hearing weird sounds like a whooshing sound from the exhaust.
By heating it and pulling the dent out you stretch the metal and may do more harm then good by making a bulge.

About 4 years ago when I ran over a piece of re-bar (about 8" long) on one of Houston's freeways and it flipped up underneath and dented one of my 1 3/4" Kooks header tubes not far from the collector. The impact sent a shock wave through the steel and I immediately got a "Check Engine" light. Turns out the shock wave had fractured the ceramic element (internally) in my R/F Oxygen sensor while not actually making contact with it. Replaced the sensor and all was good.
