I have custom ceramic coated mandrel-bent headers on one of my 3.4 DOHC's

Its crazy the difference headers make on these engine's.

With my set up, I gained 20hp, which was more then I thought I'd get.

There for the 96-97 3.4 DOHC head design with 1 3/4" primaries tapered to match the factory oval exhaust ports, v-band clamps (a.k.a. aircraft exhaust clamps), 3-1 collectors, and made with laser-cut flanges...

If I could get the "Manage Attachments" to work for me I'd post some pics.
