In my case I want to use it when I'm driving longer distances, for less noise in the cabin. I will though get a cheaper bung than you, yours seems to be great, but a little pricey for me unfortunately (mine is 1/5 of the blitz, though not programmable).<br />My plan is to drill quite a some holes, or a few larger ones (not to large though).<br />Do you think this will help the problem with back pressure?<br />/Stefanflovvnoreply@blogger.comtag:blogger.com,1999:blog-9026458778495935571.post-44959099509807229262015-02-07T21:54:57.332+09:002015-02-07T21:54:57.332+09:00Tadahisa,

It depends of course on what gear you are in, as well as how much sound deadening you have on your car.<br /><br />IF you crank up the stereo though you won't be able to hear it I think...Akihttps://www.blogger.com/profile/13586596582322556131noreply@blogger.comtag:blogger.com,1999:blog-9026458778495935571.post-80245140468500245162015-01-24T15:05:31.533+09:002015-01-24T15:05:31.533+09:00Hey aki.

Although it appears at minimum I would have to buy at least the muffler portion (no GTR fitment?). But then I'd lose the titanium awesomeness. Your car sounds (from the description) awesome, BTW!<br /><br />Aussie - I agree, RBs properly tuned sound great when not muffled. I guess, so long as I am not on boost (and I won't be as boost begins to come on about 2000rpm) the valve won't be as bad as it could be... although I DO like your idea of drilling the hole out more. This weekend I'll see if I can set it so the default is NOT "0" but instead "15" in which case there will be that much less pressure on the engine.Akihttps://www.blogger.com/profile/13586596582322556131noreply@blogger.comtag:blogger.com,1999:blog-9026458778495935571.post-82195115605268695082014-11-26T11:12:52.779+09:002014-11-26T11:12:52.779+09:00And to add I have an apexi active tailpipe silence...And to add I have an apexi active tailpipe silencer on mine and it does make a huge difference on drone when cruising and takes the edge off the note when idling.

Personally I wouldn't take the risk. The issues would occur when the engine is under load more than just revving a bit higher than 1200 rpm. So you you could set it higher so it stays closed for the neighbours and city low speed traffic when it must be quiet, but I wouldn't be using it at all when driving normally as all it would take is one on boost event and back pressure and heat could lead to detonation and premature wear. Another idea would to drill a bigger hole just to be sure but I still wouldn't drive your car with it closed.

Had to add a DB killer to the mix to pass the inspection.<br /><br />I guess the Tomei outlett + Trust downpipe + Trust decat + Tomei expreme is just too loud to quit down by only using the valve. Its crazy loud but i drive it that way, neighbors got used to it!<br /><br />My only tip for you if you really want a loud straight pipe that can be quit and safe when needed is to get a Australian Varex exhaust. Its like the new designs for the R35 from Top Secret and other brands. It closes the valve and recirculates the gasses through a silencer. But normally operates like a true straight pipe.
