Got a brand new 3.5" (90mm) electronic exhaust valve, after looking for ages I couldn't find a genuine 3.5" valve, the Apexi ones come 80mm as the biggest size !
I got this from the US made by QTP, full billet aluminium 3 bolt flange, comes with cable and toggle switch and waterproof connector
Never Used !!
Also got a "flange set" which comes with 2x 3 bolt flanges to match the valve, just weld the flanges on the exhaust and slip this in between, bolt it up and away you go !
Asking $200 for everything, I payed a lot more then that not to mention delivery from the US
Can send more pics of the unit and flanges if you require
Thanks
