4.0 v6 SOHC exhaust mods

[BirdThatsMe]

so im trying to add more power from my exhaust my cat is already hollow but I want to add headers and a electric exhaust dump but it’s gonna cost me $330 and I also want to make the Honda Civic people shut up with their crappy exhaust

It was a mistake to do that to the cats
Wasted your time on that one it's kinda frowned upon here
Someone with help you tho

I’m gonna have it on an electric straight pipe system

I was thinking vacuum controlled cutouts

I would do that but I have no clue on how to hook them up

 

[donalds]

A main vac line I can think of 2 off hand
Just install a T in the line and run the new line to the cutout servo motor

Then when you floor it or put a load on the engine the cutout will open and close when you let off

Oh really I think I might stick with electrical but I’m trying to find a 2.25 e valve and a wiring harness I already have a y pipe

 

[donalds]

Do you need just the cutout and all the harness to the dash

I can find kits with everything on eBay

Well it’s not telling me how to attach a vacuum cut out because there are some that will allow you to open at any time

 

[donalds]

You connect it to a vacuum source or directly to the intake manifold 2x 2.5" Electric Exhaust Muffler System Y Pipe Valve Motor Kit w/ Manual Switch 192840103697 | eBay Here is a electric kit

power? Not going to gain anything.....If you want just loud, stick a flowmaster 10, or 40 on it.

This is not a productive use of time or money. Get a 5.0L Explorer, throw headers and a turbo on it. If you just have $330 burning a hole in your pocket, get a new cat so you get at least dismal fuel economy instead of truly horrific fuel economy.

You do realize the 4.0L SOHC is a slowly ticking time bomb before the timing chain components fail?

 

[donalds]

Boom
I'll defuse that *****
