paul mac Posted May 4, 2009 Share Posted May 4, 2009 basically this is an electronic version of the Apexi exhaust control valve it will drop the noise level of any exhaust between 3 - 5 dB, they really quieten the car down, keep your neighbours happy and stop your ears bleeding on the motorway , unlike the Apexi once you close the QTP it forms a complete seal which is no good for the supe, to this end i had this machined out at work to 76mm so you will have to use it with the QTP digital controller http://store.summitracing.com/partdetail.asp?autofilter=1&part=QTP%2D10200&N=700+115&autoview=sku to calibrate the open position. Full details of the exhaust valve http://store.summitracing.com/partdetail.asp?autofilter=1&part=QTP%2DQTEC30&N=700+115&autoview=sku apart from the machining work, this is brand new £75 delivered, these are £130 each on e-bay SOLD Link to comment Share on other sites More sharing options...

dandan Posted May 4, 2009 Share Posted May 4, 2009 I'll take it mate. Edit: Could I fit a (custom made) larger butterfly back in there to seal it up completely? Did you open the bore of the aluminium or shrink the size of the butterfly? Link to comment Share on other sites More sharing options...

Did you open the bore of the aluminium or shrink the size of the butterfly? the housing is bored out as the 3" version of these is more like 2" 3/4 ID which is annoying, there is a gap roung the butterfly plate of around 2mm (same as the Apexi) so yes you could easily make an oversize plate, out of interest why would you want to seal it Dan Interested paul if it doesnt sell. first refusal Stav, hows project bad boy IS200 going Link to comment Share on other sites More sharing options...
