Damage from running open headers

[Nitrox]

Is there, and what sort of damage can result from running with open headers on your daily driver.

yeah, you can blow your ears out.....

Awesome! LOL

I've heard that the lack of backpressure can cause burned valves although I don't know if there's any truth to this.

You might also blow your bank account paying for all the tickets you'll be getting.

Fumes, man, fumes.

     ,   the greatest sound known to  man ! is  a V8 with uncorked headers           ,  but will prolly be on first name terms  with your local

i've heard if it's really cold out and you shut it off that's not a good combo..potential engine damage

I have heard the same thing, the rush of cold air could warp valves! But i can not confirm this, nor do I want too. I am sure someone has experienced some type of problem if it does damage a motor. We have a done it at one time or another!

i have heard of that problem with  running no cast manifold or header !! just open exhaust ports    but just that hear say !!  does make kinda sence though

Solution: only shut off inside a warm garage. Run the motor for a while so the garage is really really warm. No worries about the cold air on the valves.

good idea    !!   header wrap could do the same thing i'm thinking  , will hold heat in the header long ! while the motor cools  

not had a problem my self running uncorked headers , althugh not on a daily basis

One question,why?

Cause I want to, now shut up.

Anyway, before we were so rudly interrupted...

What I have been told is that it is safe with LONG headers. But when you go with shorties, then you run the warped valve problem because of the cooler air rushing back up into the engine. If you think about it, why would open headers damage anything? Look how many street rods and drag cars you seee with open headers and also racing at night because the "air is cooler"

That's a legitimate question....i want to know as well ?

Nitrox, quit with the Punk attitude or you'll find yourself on Vacation...again

A guy at work warped some valves by runing open cast iron manifolds. He heard the same things but figured a just a few minutes would be ok...nope.

[frederick]

Less backpressure will upset the mixture, making it leaner.
A leaner mixture will damage your exhaust valves.

So when installing headers make sure to adjust the carb.

[mikesbbody]

I had my headers installed at a friends place I had to drive from his place, back to mine (about 20 mins) but I forgot something  and had to go back to his place then back home again. Fricken loud!  on that day there seemed to be more cops around but when I saw them I eased off the gas. These are regular long tube headers and I did no damage (or at least nothing I know about) it was fun though.

true , up the jet size one or two & go from there  !! easy if you have a A/F ratio gauge

Nitrox, nobody has mentioned the electric cutout option check the site
www.quicktimeperformance.com you may have heard of them before? flick of a switch and you have open headers I'm guessing you flick the switch again to close the cutouts which takes the noise level back to "normal"? I'm no expert on their products I think I'll check the site myself

If its alright with you, can we talk about headers instead of your ploy to instigate drama?

Back on topic... 

Ive been running open headers for two days now. And its just way to loud. So Im going to cap them. I am looking at those electric valves to toggle between open headers and full length exhaust. There about fairly expensive, but the court costs and fines from the law is MORE expensive. And as soon as I see a cop I can hit that button and swtch to full exhaust and "maybe" get away with it. But open headers and plate block off s are impossible to cap when a cop pulls up next to you. So it might be worth it to get the electric valves.Its sorta of a toss-up for me on which

[flyinlow]

I have driven open headers a few times. Once for 100+ miles. No problems with the valves. Dont know why cold air would want to go up a hot header after shutdown. You can get flames and afterfire durring deccelerarion when the carb goes rich.

I am sorry , could you repeat that?

[Nitrox]

The cold air is suppose to travel up into a set of "shorty" headers while full lengths are safe. Did you have full length?

and take deep breaths?    no, don't   carbon monoxide poisoning is serious, can kill ya
