Default Open headers...

...are fun and loud . Just buttoned up a long tube header install after a busy work week. Took it out on street to "burn off some of coating residue". I gotta say with no tune and what people say about loss of power/power moving up the RPM range I still felt it pretty well even having stayed in low rpms.

Computer is going out for a tune tomorrow to really center-line her in. Thought I would share since im still smiling right now. Peace.

I ran open headers in the winter time for a few minutes in garage...car ran like **** just idling, and threw a code, turned it off real quick. Maybe I had bad luck.

The dyno will show that the bottom end will be softened up with open headers. Throw some 18" torque tubes on their and you will get most of the down low power back with no hit up top. I saw this on back to back dyno runs on my card and was amazed at what I saw.
