Re: Looking to buy 02... a few questions
I would imagine headers by themselves wouldn't yield a noticeable difference in power, no matter if they are shorties or long tubes. Most people I have seen on forums that have headers use long tubes. But those people also have more mods (heads, cam, supercharger, etc.) & get the combination tuned.
