i have an hks hi-power exhaust about a year and 1/2 now n i started hearing a leak from the driverside rear, so i when under and looked around. well i found that where the hanger is welded to the pipe, corrosion was occuring... and the whole f**king hanger broke off wtf! so my solution besides getting it rewelded was to use this JB Weld stuff, kinda like liquid steel. cost me like 6 bucks, and stands up to 500 degrees F. here are some iphone pics

i placed a piece of sheet metal over it so the stuff would stick to it, i actually covered the entire piece with JB Weld, it looks sloppy but after it hardened i sanded it smooth to the finish



after it cured, worked like wonders. no more leak, and hard as hell.

 

i f-ing love JBweld, nice work haha

 

My guess is you just screwed yourself by trying to fix the system. HKS has
a guarantee on their systems for as long as you own the car. Had you notified
the company you purchased the system from you could have received a
new HKS cat-back exhaust. Go to a muffler shop and have them insert a new
piece/hanger where you did the patch job then you'll be much better off....

man that sucks.....but i would notify the company u bought it from and tell them about this problem....good luck

 

It's too late, once you modify their system it makes the warranty null/void!
That's why I suggested he go to a muffler shop and get the hanger and
patch job done right....
