I didn't think that was accurate. I put one in and it wasn't different. Sounded like BS off the getgo.

Horsepower isn't cheap. I modified my 1988 because the engine stopped working. Make a long story short long tube headers, 2.5" pipe free flow cats and mufflers. I suppose a open lid and a K&N filter. Before you spend thousands of dollars consider buying a modified C4. Let someone else spend all that money.
