Header Headache

Hi there,, welcome to the site.

The short answer is to use the Doug's, or the more costly TTI's if your cars been lowered, and ground clearance is an issue. If you maintain regular ride height, many folks find the cheap Summit headers to be good..

Your question gets asked weekly, I did a "search" of "best 340 header", and got this
for you, for a quick over-view.
