Do long tube headers require a new tune?
My 98 has a mild cam and is otherwise stock as far as the engine is concerned. I had a dyno tune after the cam was installed.
My question is this, if I add a set of long tube headers do I need a new dyno tune or can I get by with a mail order or no tune?
I'm not excited about adding another $500 to the cost of headers if I don't need it...
Also, will the headers change the exhaust sound? I have a Z06 Titanium exhaust axle back system.
