How long is a 1968 Buick LeSabre?

How can I make a single-exhaust 1968 Buick LeSabre (V8 350, 4bbl. carb) into a dual exhaust, and will I get more power?

• Answer:

  u ill achieve more power and it is always possible to do dual exhaust its just that sometimes its not rear exit exhaust and u might have to settle for side exit exhaust like around the front of the rear axlebut yeah man its possible the larger the pipes the more power it creates less restriction
