I'm selling my helix test pipes for non-rev and revup motors. The driver's side already has an extra bung welded in for an aftermarket wideband sensor.

Used them on my G for about a year before going with my turbo setup.

No leaks,not dented, never been welded like alot of the test pipes you see on here.

Looking for 125$ shipped. Test pipes only, no header flange gaskets unfortunately.

 

You still have these?
