The Big Dog for the 1970 Mopar Model Year was the 426 Hemi.   Our Hemi system comes with the correct 2 1/2″ H – Pipe with correct flats for the torsion bar, correct welded on heat nipple (functioning or non functioning) correct welded in cross over pipe, correct flanges our H – Pipe necks down to 2 1/ 4″ where it goes into the muffler because that is the way it was done. The tail pipes on the HEMI cars used a 2 1/4″ tail pipe with a resonator on the end. We have reproduced the correct date coded and part numbered resonator welded to the tail pipe as original.  This system comes with the correct style mufflers dated coded with correct flats on the side, installation instructions, diagrams and sealant. Decor package tail hangers, correct rubber looped front hangers and correct round bottom style  mopar clamps. are available as well.  No decor package mopar would be complete with out the chrome tips so let us know what model you have and we will make it happen. Ask about our concourse show package for those of us who like it a little more real than real.
