I have a Gil tailpipe/ riser that has a hole in the inside pipe. It is a silent choice pipe but if I found an HP500 set of risers that would work too. Any suggestions? BTW, I know I can get new Stainless Marine or Imco or whomever else but I am but I am trying to find the most economical solution to my problem so I can install other upgrades.

where is the hole, before or after the arch?

i have 2 gill hp500 risers

It is at the top of the bend. Where the exhaust would be going directly up from the manifold.

i am a metal man
corroded risers ,headers really are not worth fixing
is the 100 dollars fixing worth a roached motor
spend the money call it a day

Looks like I am going a different route.
