The inlets are closer together than most 914-6 headers, so will require alteration for most applications. The headers this came off of were only 17" apart at the flanges.
I think the ends of the megaphones could be modified without too much trouble, so the inlets are spread a couple more inches for the standard width shorty headers.
Be forewarned, this muffler is pretty loud, although there are small inserts in the outlets to help control the sound level.
A simple muffler mounting bracket (attaches to the band clamp bolts) is included.
