Headers and Glass packs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Never done this before . I'm thinking of adding headers and glass packs to my '72 blazer. The exhaust that is on it has had it from the exhaust manifolds on back . What if any are the drawbacks to going to a system like this. I have aquired some Hookman Comp. Headers already and the glass packs are just so much more cost effective then mufflers.

Any help or info greatly appreciated.

Welcome to the board. Depending on the laws in your state or community, they have something to say about the noise. I think they sound good, but there isn't enough back pressure on the engine.
