However a little trimming may be necessary as it is a bit tight with a couple of the tubes. At one time you could use Hooker #2453's, but they have since changed the tube layout, so I don't know for sure if they will still work

Does anyone have a say about the exhaust manifolds from Allstar Performance? How do they fit/perform?
