Almost at the point of starting to rebuild my cossie and always wanted to fit the full stainless as it was before but then have a y piece welded In with a butterfly valve and then also a wrc style side exit letterbox exhaust just for the extra sound when hooning 😉 I've seen a exhaust advertised for about £1100 but not seen one fitted to a saff

 

Try Marc Kinzey mk he has a resto thread in restos and rebuild section he's made a few now I think drop him a pm

How you going to open the butterfly?

On my Escort rally car it has twin side exit. One has a silencer and a catalyst the other has nothing. My butterfly valve is controlled by the ecu on boost pressure. Below 0.5bar everything goes quiet and through the cat. Above that through both.

 

My mate had a saph with a side exit it sounded awesome. Bit noisy on a long journey though. Be good to choose between having it open and not

 

 

Ahh ok so just open/close.

Mine opens different amounts in line with boost.

 

 

 

I was just gunna operate with a switch or maybe remote , but really want to see some pics of em fitted to cars

 

I am doing the same thing with a bypass valve when I get my car back from the bodyshop the valve and pipe are sat here waiting for me to fire into it

 

I don't have a letterbox one, but I just made the side exit for my rally car. Used a standard type aftermarket exhaust as a basis and, where it went round the fuel tank near the sill, chopped it and made up a section to drop out under the skirt. Had to put a bloody big silencer into it to get it to meet noise regs though. I guess a turbo car might not be so bad though.
