db killer - IVA friendly?

Whats the chance of this passing IVA? Or taking it and sticking it in the exhaust if it is too loud?







If it ain't broken, fix it anyway (just because).

I suspect it will be at the discretion of the tester....it could only be fitted after the emissions have been done...

Furore Formula Car - the only two seater modern Formula Car lookalike. I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours. http://shop.ebay.co.uk/furoreproducts/m.html?_dmd=1&_ipg=50&_sop=12&_rdc=1

I fitted one of those from Russ, after failing my first iva on noise, worked a treat and knocked 6db off.

It's fallen off now though

It's mild steel so I'm sure a bit of pipe and a welder the outer bit could be made to fit in a 3 inch pipe.

i made up a baffle and put it inside the pipe before the silencer. drilled a small hole through the underside of the pipe and put a rivet in to hold it in place.
