Thinking of building my own PSE (parts)


Recommended Posts

yep, thats the plan atleast :blush:

Im just in love how the original PSE sounds and first the muffler bypass was on my mind.

But why not go all the way, including remote operation?

In my mind the electric vents are useless but they are realy easy to find. And the effort to build a DIY PSE should be on the lighter side.

The vacuum ones on the other hand, they are not what i would call cheap and hard to find :huh:

I have tracked down one supplier for the electronic for the vacuum actuator, http://www.carnewal.com/products/P57/p091/Installation-Set-for-Switchable-Exhaust-via-Remote

Now to my question, does anybody know if the actuator is open or closed under free condition?

Hi from Norway smygolf!

I am currently building a homemade PSE. I will post a full write-up when I get done, but here is the basic idea:

-I am welding up a bypass similar to the stock PSE, I will use vacuum valves to allow part of the unmuffled exhaust to go straight to the outer muffler chamber and out the tips

-OEM dash switch will turn the good sounds on and off

-Parts list includes box S muffler, stainless piping, exhaust valves, dash switch, latching electrical relay, vacuum solenoid valve, vacuum tubing, wiring.

So far I have most of the parts, I will be ordering the last bits next week and hope to have everything working on the car by February. I will get the kit from Carnewal also, but the solenoid valve he supplies is closed in a free (no vacuum) condition, while the exhaust valves are only available open in a no-vacuum state. Since I want my switch to determine on or off without supplying voltage and keeping the solenoid on when the exhaust is off, I sourced a solenoid that has connections for both normally open and normally closed states.

I'll let everyone know how it goes. :-)

I found an easier way, sounds better too..

I basically cut open the muffler from the top (had it out because I fixed my wobbling transmission shifter shaft) and cut out some of the internal piping (along the black lines in the pic)and closed it up again. The exhaust flow now has a more direct path to the tips.

Thanks for the responses, both the "stealth" internal mod and the Pedro-style mods are fine for an OEM exhaust mod.

However, you'll see that the OP wants to do a PSE style exhaust with valves for remote on-off operation. Thats what I am currently building as well and will post a full write-up when done.
