The OEM "b pipe"(the pipe from my Hotshot header to my OEM exhaust) seems to be rusting my 94 SER. The headers 2yrs old and the oem exhaust is new,so I want to replace the old B pipe. Anyone know a ballpark $ figure on a replacement if I went to a shop? Either OEM or Custom from a MufflerShop or the Stromung? What do you recommend? Thanks, Mike 94SER
