Exhaust Valve Shutoff

[Timbo126]

Does anyone know of an exhaust valve that could be used for a 4" pipe. I was thinking about running a dual exhaust setup coming out of a Y split after the downpipe. One side would have a muffler and maybe a resonator for when I want the truck to be quiet. Then the other side would be a straigh pipe for performance. Has anyone ever seen this?

That sounds like a neat idea. Look into some of the hot rod companies that build exhaust cut outs. Post up good pics if you get it worked out.

Mudrunninpig has something like that on his truck... Might want to shoot him a pm.. His is for his stacks to be turned off when he wants. It's a great idea..

I like the idea of this but would this kind of set up create any unwanted back pressure?

jegs, summit... they have stuff like that. Just google exhaust cut offs, bypass valves...


Neat idea!

I suggest upgrading to a 4" or 3.5" down pipe that connects to the Y pipe with the valve. But it is totally fine to use the stock 3" down pipe.


To make it enough of a difference / worth the effort,
On one side,(I suggest the drivers side) have the Y valve feed a 5" pipe for the big fun sound. And the other side (passengers) to a 4" or 3.5". I suggest the 3.5" for better sound deadening.
Use the Stock exhaust system with cat and muffler delete pipes and install a flow through muffler. After the down pipe the stock exhaust size is 3.5".
If you like the idea if using the stock exhaust design, either keep the stock down pipe or upgrade to a 3.5" downpipe.


^^^ that is if you want to keep the tail pipe exhaust design. You could also use a stack for the loud sound.

Are you talking about the ypipe creating back pressure? not if it is the same size as the down pipe.

Well I have a 4" TB back exhaust now which is cutoff on its way down from the axle near the spare tire so you cant see the tip. I was thinking of adding a muffler to this pipe and possibly a resonator if theres room. I got rid of my stock exhaust so thats out of the question. I didnt see the cat as being much of a sound reducer anyways. Then after the downpipe do a Y split with a 5" straight pipe which will run to the other side of the frame go over the axle and on its way down get cutoff. Is there enough room for this or will the fuel tank be in the way?

Looks like I found one for a 4" pipe

So I talked to a shop today about bending the extra pipe for my ehaust idea. They were saying that it would be super hard and expensive to run another 4" pipe along side the existing exhaust pipe. But we got talkinig and came up with the idea to put the Y pipe valve right after the down pipe. Then come straight off with the standard exhaust. On the other side of the valve we would come off with a short 4" pipe and then turn it down right before the axle. Does anyone know how a short exhaust would sound.
