RedLudeSH Posted April 20, 2012 Report Share Posted April 20, 2012 Does anyone have the tools/know-how to re-round 2 tubes in a stainless steel header that have been not only flattened, but shoved inward a bit. The piece it happened on is only maybe 14" long and its on a flat area. Thanks Here's where the dents are... http://i64.photobucket.com/albums/h182/redludesh2/headerpic.jpg Quote Link to comment Share on other sites More sharing options...
wnaplay1647545503 Posted April 20, 2012 Report Share Posted April 20, 2012 Probably easier to have it cut out and new welded in. Quote Link to comment Share on other sites More sharing options...
Guest Spam Posted April 20, 2012 Report Share Posted April 20, 2012 I hear IPS is god at denting things... :gabe: But you could try the dry ice technique. Or exhaust shops usually have the tools to do it. Quote Link to comment Share on other sites More sharing options...
Rocky31186 Posted April 20, 2012 Report Share Posted April 20, 2012 I did custom exhaust for 4 years and have no idea how you could flare the pipe back to round. I would cut it off and replace that piece. Quote Link to comment Share on other sites More sharing options...
Dumpheezy. Posted April 20, 2012 Report Share Posted April 20, 2012 I wouldnt bother...it wont effect your performance on your Prelude enough to worry about it. I smashed up my header for months after getting dynoed on my supercharged GSR setup and threw it back on and made the same power... Quote Link to comment Share on other sites More sharing options...
Dumpheezy. Posted April 20, 2012 Report Share Posted April 20, 2012 Oh....and are you tuned? If not, youd make more power from getting tuned then trying to fix your header. Quote Link to comment Share on other sites More sharing options...
Qtr_pndr Posted April 21, 2012 Report Share Posted April 21, 2012 fill it with water and put it in a freezer Quote Link to comment Share on other sites More sharing options...
RedLudeSH Posted April 21, 2012 Author Report Share Posted April 21, 2012 I don't understand the water, freezer thing. The dents are really bad, almost pinches. It was a very expensive header that is no longer made. My car responds very poorly to basic mods as it is and I know these dents are very bad. The only solution I've seen that makes sense is heating it till it glows then pounding it out. It's thick stainless steel. Just didn't know if anyone had the means to do it.

Cordell Posted April 21, 2012 Report Share Posted April 21, 2012 If its as bad as you say it is, have someone cut it up and remake the damaged part. Quote Link to comment Share on other sites More sharing options...
AJ Posted April 22, 2012 Report Share Posted April 22, 2012 build block off plates for both ends and fill it with compressed air then heat the dent and around it. be careful or you can blow the pipe apart. used to remove dents all the time from dirt bike pipes this way.

MattKatz Posted April 22, 2012 Report Share Posted April 22, 2012 This will sound funny, but an instrument repair place can do it. They repair dents in saxophones, tubas, etc. I had a motorcycle header repaired at hauer music here in Dayton one time after a bike went down, guy did excellent work. I'll see if I can find before and after pictures. Quote Link to comment Share on other sites More sharing options...

If they are as bad as you say, the heating method may not work. Quote Link to comment Share on other sites More sharing options...
