High tech twist on a old school mod!

I just ordered my electronic exhaust dump-out (exhaust cut-out) I am going to try to put it between the cat and muffler (provided anough room) the wire to a switch. Driving on the streets, nice and quiet, flick a switch and, "what can't hear you over that awesomely loud jeep" Found a good deal on one, $80. But it only has the Y fitting and the electric manifold, and is weld in only. I am going to fab up some high exit pipes for it.

I have a pair of those on my 67 mustang, but they wern't auto... I had to crawl underneath and take a plate off each side. The one you have is electric? Never seen one of those, I have seen one with a cable but I hear they break easy... I wanna see pics when your done!
 
This is very similar to the one I ordered.

WHERE THE HECK DID YOU GET ONE FOR $80????????????????????????????????????????????????????????????????????????????????????
 
ha i just bought a 20$ cherry bomb and am planning on weling it on. Just dont get on it around cops and ill be fine. Most my freiends are straightpiped so ill be fine!
 

tell me about the motorcraft carb

I can only get one. It is kinda used. put on to a show car, but never wired. And they threw in a flowtech Y fitting, $80 cause I also traded a 41 plymouth complete dash.


As for legallity, there is no law about possesion, just use, and this is a strickly off road usage.

Back pressure, the cat should provide enough back pressure
 
if it is used for street racing... the intimidation factor rises a lot.... we need to find a 3" dump for the camaro we just supercharged.... he's blowing header gaskets weekly, or more.... even with NO cat, and a good free flowing muffler, he's still go too much backpressure
 
First, if your blowing head gaskets, turn the boost down a bit. If it is a 9:1 compression (stock f-body lt1) too much boost will detonate the motor. Do you have some type or retarding mechanism?
Running long tube headers?

I don't think too much backpressure is what is causing a blown head gasket. Is there liquid coming from the exhaust pipe, and is there a anti-freeze smell in the exhaust (don't spend too much time sniffing)?
 

not head gaskets.. header gaskets/exhaust gaskets... we've looked into it all... we know the motor is safe... we just can't get enough of the exhaust to go where it belongs
 

u-bolt yoke conversion

wow old topic revival jps4jeep, but where did you buy this from? i gotta buddy tryin to find an electric one
 
For the Header gaskets I would look into metal ones. We just got them in at autozone. They are supposedly soft metal and can be reused over and over again. It might be worth a shot. They are not behind the counter then are in Isle 6 with the chrome perforance stuff.
 
Who's In?

What engine are you running in it, and what size are the headers? My favorite solution to a problem like that would be to dump the rest of the exhaust system, and just run the headers :lol:

That would be sweet having an electronic dump. Pull up to someone at a traffic light...rev it up a few times, then open it up and rev it...that would give them a little supprise :shock:
 

we put in a manual cut-out... ooooh boy is it loud... runs a lot better like that too.. not too much backpressure that way
