[Sideways]

I have three trucks I drive right now, two with headers and one with manifolds.When I had the exhaust done on my 72 GMC I had the fellow use 2 1/4" pipe and it works well. With a rv cam it still sounds stock,but with my DD I used 2 1/4" and headers and still running the stock cam it does sound hotter than the stock manifolds.

I personally have not had any issues with headers mind you I have always bought new Hedman's and I love the sound of the cam when using headers.
