Ive got stock pipes on the 1987 454/330. Just curious how it would sound with some headers (like stainless marine for example). Are they just a direct bolt-on, or do I have to do some rerouting of hoses. Ive got the raised X, so would a set of headers rub the hatch? Just kicking around the idea for sound reasons only. Basically the same reason I have super 40 flows on the truck. They may have actually reduced the HP from stock, because all I added was the muffler and K&N filter w/o changing the computer. But it sure sounds better.
I currently have the Gil stainless mufflers that look like a slash cut tip, but have a spiral baffle inside.
Thoughts?
