Open Headers

Hi, I was just wondering, out of pure curiosity if it is illegal to run open headers?

It's illegal where I live.

It probably is where you live, because of the extreme noise level.

if you have to drive this vehicle with open headers to a local exhaust shop, give the local police a call and let them know that's what you'll be doing. They will let you slide.

Darn close to open headers

Find some heavy wall aluminum pipe and run it off the collector/ reducers.

For cruisin, it will get you in the legal Db range

go this route

and you can run them open at the track or when you think it's safe, but shut it down when the fuzz is on your back. or they also make headers with a dump tube you can bolt up manually.

holy mackeral taco502!

$$$$550 for butterfly valves in the exhaust to control noise!

It's less than $55 (?) for 2 pieces of heavy wall aluminum electrical conduit (Lowes/Home Depot)
Use some curved bend pieces if you can for less 1500rpm resonance

Plan "B", just to make noise, is the old fashion "choke cable control cut outs"( J.C. Whitney), they still make them.

I had to drive about five miles to the muffler shop with open headers. That was enough for me...but I'm older...and probably a little deafer.

Bet what he's using on the pipes in your pic' are collector inserts.

A little hard to describe. It's a steel tube with rings of steel around it, usually 2-3 rings. Each ring has a number of holes in it that don't line up.

This lets some exhaust go directly down the center, the rest has to find it's way thru the holes in the disks which cancels out the noise.

You can find them on the Jeg's or Summit sites I bet. $80? + welding and fitting.

Same idea, more money are "rat-trap" mufflers. Kinda nice cause you can add/remove discs to tune the exhaust.

.................................................. ................................................

the no fenders, I've never done done it except on a bike and it ain't no fun in the rain!

check your local laws, I believe here in Oregon you can run w/out fenders if it aint raining, and if it is raining I think you can get away w/ just mud flapsor a small fender that just blocks the rear of the tire, (like truckers w/ the trailer)

I think you could adapt the EFE exhaust butterfly from a GM car as a cut out. they are vacuum operated and it shouldn't be much trouble to adapt them.
I think roadster style exhaust with some supertrapps might be cool but it would probably get old fast.
I have one friend who has an old T-bucket with a flatty that just has zoomys and it sounds so right, and not too loud either. Of course that is a flatty.

The car in your pic' I would call a "Laker" style.
The very first rods, in CA, raced for top speed possible on the salt lake flats.
The didn't have alot of power so the next best thing is no weight and streamline it so off with the fenders/bumpers/etc.
That's why the full disk wheel covers, "streamline" the wheels.
A stock model T winshield folds down, bet the windshield in your car pic' folds down to help with less drag.

Most were a weekend good weather race car. They did drive them to the flats outside LA with no fenders etc.
