matt b Posted January 29, 2009 Report Share Posted January 29, 2009 Pretty sure I'll do this after I finally get Joseph's old exhaust welded onto the wagon. And yes, salt is definitely an issue here. Link to comment Share on other sites More sharing options...

I was just going to link up that thread. Gold star for you To those who think SS will mean you are rust proof, stainless is called that because it resists rusting better than regular steel; however it is not stainproof.

Gold star for you To those who think SS will mean you are rust proof, stainless is called that because it resists rusting better than regular steel; however it is not stainproof.Correct of course, and I've learned that different qualities of SS resist better then others. Most high quality DP's will resist pretty well. I wrapped my DP and then sealed it with heat wrap sealant (paint really). I used the Inferno wrap (3000 degree) wrap and then sprayed it to keep out the water. Link to comment Share on other sites More sharing options...
the commissar! Posted January 29, 2009 Report Share Posted January 29, 2009 I'm going to try this in aluminum Product DescriptionThe High Temperature (HT) Silicone Coating provides lasting protection for any hot surface up to 1500 degrees. DEI recommend the use of this coating with their exhaust wrap because it seals the material and provides lasting protection from oil, dirt and road grime. Don't limit the use to exhaust header wrap, this products works well on headers, blocks, starters and even on your grill at home. * Heat protection up to 1500 degrees * Seals and protects exhaust wrap * Many uses around the home and shop * One can enough for V8 headers Used correctly on clean dry wrap should significantly reduce the rusting problem. Wrapped my DP last night down to just past cat. It's sitting under a celing fan drying as we type. Link to comment Share on other sites More sharing options...

I got the 100 foot kit from Summit for ~$85 including shipping but I’m doing 2 cars. 50 foot will get you 10 feet on 3” straight pipe. Depending on # of bends it will be less. Then you’ll need fasteners. GL Link to comment Share on other sites More sharing options...

Hellas850 T-5 Posted January 31, 2009 Report Share Posted January 31, 2009 well I don't believe that any rust or corrosion could lead the pipe in failure in short time,the thing is,are the advantages more than the disadvantages(the one until now).Personally I will wrap at least my downpipe,because I don't want to burn everything around there.

the commissar! Posted February 1, 2009 Report Share Posted February 1, 2009 unless you have a cheap mild steel exhaust or you over wrap it (trap too much heat under wrap), it should not be much of a problem. I think if you use a properly prepared and applied quality high temp paint, to prepare the surface for the properly installed wrap and silicone coating you should be GTG for a long time. I think it is a waste of time to prepaint but my catback came with it so...I'll compare how long it lasts compared to my naked wrapped downpipe.
