Wired open by-pass valve on 355 with Tubi??

Calling GrahamS...

(his is wired open).

just wire it open and go for a drive if its better leave it if not put it back to standard or ring karl verdi he will know

 

I've got the same set up as you but have also wired open the by pass valve.

To be honest it's a little agricultural at idle and I can't deny that you lose that second stage transition.

But, it's a lot noisier around town and the sound bounces magnificently off buildings at low revs

There's a video of my exhaust knocking around on here somewhere. See if you can find it and listen for yourself.

At the end of the day it's only a 5 minute job to wire it open so if you don't like it you're not stuck with it

 

It's not gonna do any damage wiring it open then?

 

Don't think so. In fact I was told the opposite in that it had prevented heat from building up and saved my cats from totally disintegrating(this was before I took the cats off of course!)

Edit: Chaa, I presume you're going to the Conkers on Sunday? If so then I'll give you a demo of how it sounds and you can see for yourself if it's the way you want to go.

 

I've just read on another thread that it will damage the exhaust headers! Worth thinking about.

 

Have you got a link to this thread?

 

i cant see how it would damage the manifolds al it does is letting the exhaust gases out quicker without going through a valve

 

Not everything said on FChat is true. In fact, quite a high percentage of it is bollox !

For what it's worth, I thought it sounded great at idle too

 

Stick some K&N filters in too, if you haven't already done so

 

Have you got an Essex boy "Kevin and Sharon" sun strip at the top of your windscreen too?

 

I couldn't find it when I searched again so I had to go through my history.

The dude was from Switzerland................(I think you may have gone unnoticed.......hang on, we'll give 'em time to finish their brekkie!)

 

Most of the rubbish come from *whispers* 'other countries'...........Chaa!...............Chaa, I'm on my way......

 

As you say, the manifolds go anyway, it is down to a specific design fault as far as I can see.

Can't see why the bypass valve being open or shut would make any difference, seeing as it opens and closes all by itself in normal use.

 

If it opens and closes, then why does it close?

 

Paul

EU drive-by noise is I believe the primary reason it closes, it is also alleged to give a bit more torque at lower revs with the valve shut due to greater back pressure

As others have said open or closed won't affect the Headers/Manifolds which basically are made of metal that is too thin

 

And YOU used to slag off TonyH for recommending Karl Verdi
