Default Are headers noticeably louder than cast manifolds?

I am considering putting some Dynomax headers on my L48 but am concerned over noise.

what year? duals? removal of the cat makes more music (noise) than addition of headers.

They will make the car slightly louder, but the size of the exhaust, length of pipes and mufflers used have more of a bearing on the loudness of the exhaust. Get them, you will not regret getting them, they change the tone and sound of you car. IMO headers sound cool and they boost HP.

no brainer....get them...get them with ceramic coating.
lil' louder, better breathing of heads, more hp, less heat under hood(with ceramic coating that is) did we mention more HP ? :yesnod:
