hadyn Posted August 31, 2010 Share Posted August 31, 2010 Hi all, The HKS backbox on my Legacy has developed a largish hole. The backbox itself is fine, but the pipe going into the backbox is where the hole is. The pipe is pretty badly rotten so I dont want to weld a patch on it. My question is, would it be possible for a decent exhaust place to remove the old rotten mild steel pipe and then weld a fresh piece of stainless pipe to replace it?

kjgreen3 Posted August 31, 2010 Share Posted August 31, 2010 I think a decent garage would be able to weld a sleeve over the entire pipe from flange to where it meets the back box. Whats this for permanent fix? just for MOT? temporary until you source another backbox/exhaust system? However it may just be cheaper to get a new backbox or a decent second hand system. BTW is the HKS fully stainless or is just you want the repair to be rust free as im not 100% if you can weld stainless to mild steel. IF you want a temp fix for an MOT I can give you an amusing fix that worked for me. Quote Link to comment Share on other sites More sharing options...
