Hyper-pak questions

NOT
It was not a Header, it was 2 cast manifolds.
Hyper Pack was an over the counter buy and you could buy what you wanted. All of it or just 1 part. The exhaust used a Y pipe to connect to a large pipe and muffler assembly.
So your Lancer just had someone add a large exhaust pipe to what looks to have been a stock manifold, or perhaps a feather duster/dart lite exhaust manifold. Might have had a 4 barrel with the cable added, but Hyper Pack had the rod type linkage, not a cable.
But! Any Lancer is a KEEPER!
