butterfly valve exhaust?

[spaz1879]

You have 1 throttle body, its located at the air inlet. The part coming off the engine is the exhaust manifold.
Your DUAL catalytic converter is 1 converter. Converters are made up of 3 precious metals. Front converter has 2 of these, rear converter has 1. You would need to split the exhaust after the converters to keep it street legal. As long as you don't remove the converters and the exhaust exits out from under the truck, you are still legal.

are you sure that the exhaust has to exit out from under the truck. what about stacks?

Stacks exit out from under the truck. Some states it has to exit in factory location. I'm pretty sure all states require it exits out from under the truck. Is it something you will get busted on, probably not. But with a ranger with a sliding back glass, if you exhaust exits under bed and you have the window open, you will smell exhaust fumes.

Having said that, I have a turndown after my catalytic converter. Muffler got torn off 4wheeling, and i don't feel like putting it back on. It's not loud enough to bother me.

i used a warlock mufler on my 97 with the 3.0 with the removable cut out. it was bad ass but you had to go under the truck every time to pull the plug with 3 wing nuts. but sumit racing sells 3 or 4 different cut outs that seem to work well.

you gotta watch that stuff in PA...I've had exhausts fail emissions very easily. they have some stupid laws since rendell took over

what he is saying is that he has spare parts , so he wants to make a valve using old throttle bodies , and he wants to run 2 mufflers on this truck , he wants to make a flange that the muffler will go onto , that bolts to the intake manifold side of the throttle body , there fore allowing him to control the path of his exhaust

and last time i checked stacks exit on the topside of the truck , and if all stated required that it exit out from under the truck , semi's would be illegal in all 50 states , about a dozen kids at my college have trucks with stacks , and they are legal

I thought about doing this but just a straight pipe, so i could have the muffler when I need it, and a straight pipe coming out the factory exit when I mud. But I just ended up putting a perminate muffler on... Maybe when i drop a v8 in so it wouldn't sould so much like s**t when its straight piped.

poor guy is confused

I think one issue with using a spare throttle body to change exhaust flow (like the electric and cable operated header dumps) is that the throttle body isn't sealed very good. The butterfly valve is tight to the TB's bore, but its not sealed. I would be afraid of "psssst psssst psssst" and other annoying sounding exhaust leaks when the throttle body has directed the exhaust flow to the muffler. I get anal about exhaust leaks, its one of my pet peaves. lol, but maybe you can deal with that.

 

[mongo]

hahaha you whould hate mac then

its an old 73 f100 with i think 6 big header leaks and 3 nice gaps on the pipe

hes down for the count right now


but my ranger has one somewhere i havent found it yet

i can only really hear it on really cold days and it to damn cold to find it

 

[Original_Ranger84]

You would also hate me I have a Massive leak right at the end of the y pipe, I have everything to fix it atleast. and the leaks would be in the throttle body and not leaking to the outside, I think he is saying that the throttle body isnt seal around and will let a small amount of exhast through the other pipe even when its closed.

i know its an old thread but here is the muffler that was mention a while ago. its called a power effects muffler. its a tuneable muffler, that has a knob to have the option top run straight pipe http://www.powereffects.com/tech.htm

No, no, no, no, no. Do stacks expel the exhaust under the truck? No. If it's not "under the truck", then it must be "OUT from under the truck", or if it makes more sense to you, "NOT under the truck". It doesn't matter where the pipe goes on it's way to the exit, as long as the exit isn't under the body.




a buddy of mine had an electric cutout on his Camaro. It would last about a month before it would start leaking and rattling and sound like general ass. Then he'd send it in for a replacement on warranty. He gave up after about 4.

 

[rurouni20xx]

well heres my take on cutoffs, they are legal as long as the rest of the pipe exits in a legal manner per your states requirements whatever they maybe. you are going to hate them, a friend of mine had some on a dual setup (duals out the back w/ mufflers, then duals out the sides strait pipes) and no matter how you adjusted it, it leaked like crazy. killed his mileage and he got tickets cuz both pipes were on all the time, just moreso to the straights cuz the backpressure from the mufflers pushed the gate open. if there is another form of cutout you can use, go w/ it. the regular valve ones are junk.

I would consider one of these...

Why use two valves when it can be done with one?

Instead of the extra plumbing and expense of a glass pack, just use the muffler or have a straight pipe. Yea---Make some noise.
