These mandrel bent downpipes are the only mandrel bent 2.5 in. downpipes to connect directly to your stock 351 standard manifolds via a clever ball socket and flange connection. They are very easy to install. Expect 5-8 extra horsepower because of the 2.5 in. and smooth mandrel bends. These downpipes end right at the cross-member humps so they will easily connect to Pypes PN
|SFM03||header back system without modifications. 5.8 Litre engines. Will fit any 64-69 Mustang with 351 CLEVELAND style manifolds.|
