Redneck Restoration's "This Old Truck" Part 1 of 2 Straight Six 292 Header Install
The claim is that a header on your straight six will gain 20-40% HP and/or
torque. In this case, it's definitely true. (I'll get some road Dyno footage later, but for now
you'll just have to take my word for it.) The carbs initially improved the
big end, and it would keep pulling strong as fast as you wanted to turn it.
(That's ok if you feel like grenading the engine) There was also hill
climbing inprovement due to the larger CFM being able to pack more fuel
charge into the cylinder. Ran it with straight pipes off the header for the
8 miles from the farm to the muffler shop. Wide open throttle performance
was non-existent. Fell flat on its face. Once the rest of the Exhaust system was in place, it was like a
completely different engine. Was able to pull the "test grade" without
losing any speed, where it used to drop about 7 MPH. Our other "test grade"
is "Hayes Hill Intenational Speedway", a 2 mile hill from mile post 14 to
16 on Hwy 199 in Oregon. Went from dropping to 3rd at MP 15 to about 15.75.
Now that's truckin'!

HOW TO make your exhaust LOUDEST
*STOP the comments on how bad the welds were. I know they were shit. Take
a look at the rust I was welding on. This was one of my first times
welding. I didn't know you had to get the welding surface to bare metal
back then. Also, I was working with a 110 harbor freight welder.*

2014 Audi RS4 Insane Straight Pipes Exhaust Sound!
I went for a ride in a friend's brand new Audi RS4 Avant B8 fitted with a
custom straight pipes Exhaust, the
sound was just unbelievable! First you get to hear a series of brutal revs
from the 4.2L V8 then we go for a drive in the tunnels, I've never heard
such an insane sound like that from an Audi!
Jeep Grand Cherokee 4.0 Straight Pipe Exhaust
Straight pipe in place of the muffler on my WJ. Stock 4.0 with stock
intake/headers/cat/tailpipe. Has a nice sound but is loud and drones
inside at 1900-2400 rpm, which the video doesn't capture. Highway cruising
is nice and quiet at 55-60 mph, but the interstate at 70 mph/2100 rpm would
drive me crazy. I'll almost certainly end up with a Flowmaster 50 Delta
Flow to mellow it out a little. I posted another video of a Cherokee I
used to own where I did the same thing, but the catalytic converter was
much larger and the end result was much more mellow than this.
UPDATE: This setup was fun for about 1 week, then was just completely
annoying and I hated driving it. It was an unrefined sound, it really
howled at 2000 rpm to the point where it hurt your ears, and I also lost
torque on the bottom end. I just installed a Dynomax cat-back with their
Super turbo muffler and absolutely LOVE
IT. Flows better than stock, moved my torque curve back down, has a great
looking tailpipe, is barely louder than stock and really has a great tone
to it. I've got an initial video posted and will post another in a couple
months after the muffler has really broken in.
