The Stillen HFC and Y-pipe came from a complete exhaust I recently purchased. I was only interested in the mid-pipe and muffler so I have these for sale. Parts has less than 8k miles according to previous owner...HFC in goos shape except one of them has a cross-threaded bung. It should be an easy fix by having it re-tapped or even weld another bung on it. Inside catalyst in clean.

Asking:
HFC = $320 obo
Y-Pipe = $200
SPC Toe Bolts = $30

I'm in the Temecula area (Riverside County...an hour from San Diego, an hour from O.C., an hour from L.A.)
