Exhaust divertor valves - the kid in me

[brachunky]

Had the LS 400 since July this year & quite enjoying the ride to be fair. However.........................despite the p/o fitting a few VIP trimmings, I don't think its the style for me and tbh, to do vip properly its a big buck situation! So, I'm thinking about making a few mods that I fancy and the first one is to make the car sound a bit more "muscley" if there is such a word. It has a year old custom system already on with no rear boxes but leaning towards a pair of those pre silencer exhaust valve jobbies to complete "my sound"
I have been googling locally and did'nt see any at the NEC yesterday so who has found,fitted and tried these little things?

Example of chinese version

Haven't used one but I am very interested in getting some so will follow this.

I've seen some on eBay going for over a grand which seems obscene for what you are actually getting.

Yesss

Going onto my truck.





I think it needs to be done.

Can you set them partially open?

Hallo sb

Yes you can set them any way that you need.

Are these not just electric exhaust brakes?

This is what they do

These are on porsches, known as psm. It bypasses most of the silencer, has a push button on the dash.

Mint! Get a couple of DB meters and an Arduino and you could set that up how you want.

Many years ago I had a '92 plate E36 328i, it had factory standard twin tailpipes.
1 pipe had a vaccume operated butterfly, the other was always open.
(1 open = improved low down torque, both open = flat out power  )

Probably ebay but I'm not quite sure

I've struggled to find many non-chinese models, not that there's necessarily anything wrong with the Chinese ones, but it surprises me that there's not more options.

May be a bit too much after import taxes etc but no doubt the quality is great

These are very good.....

Quite a few production cars have electrically driven valves in the exhaust front pipes for ECU controlled forced EGR.
I'll bet with a bit of investigation theres a low cost scrapyard solution to sourcing these, a common model thats in plenty of yards where the valves could be chopped out and something home made to control them.

I remember from a while back Isuzu Troopers had these these valves, Although I can’t remember if they were electric or vacuum operated, might be worth a look.
