MANWHORE Posted August 2, 2006 Share Posted August 2, 2006 works with anything. just cut off and replace one of the flanges. I've said it before. not worth the trouble. Basially, it doesn't lower the noise much. Also, if you get epa'd, they'lll just open the valve, because it's a variable noise controller.

mad082 Posted August 3, 2006 Share Posted August 3, 2006 you'd be better off just putting a silencer in the rear, like what most systems come with. no cutting, and much cheaper.

silva33 Posted August 3, 2006 Share Posted August 3, 2006 I had the same exhuast, it still failed EPA with the silencer in by 2db... i had to install another resinator into the system either that or install a mid muffler. By installing the silencer your car will aslo stop making power at a certain rwkw like mine did..

Mandingo Posted August 3, 2006 Share Posted August 3, 2006 Get a resonator, any exhaust joint could add it to your blitz system. silencers are teh gayest Link to comment https://www.sau.com.au/forums/topic/128643-apexi-exhaust-control-valve/#findComment-2380406 Share on other sites More sharing options...
Mr. Oizo Posted August 3, 2006 Share Posted August 3, 2006 just get another mid muffler installed, but flanged, so you can remove it for track/drag days and put it back in when you're on the street Link to comment https://www.sau.com.au/forums/topic/128643-apexi-exhaust-control-valve/#findComment-2380422 Share on other sites More sharing options...

Mr. Oizo Posted August 3, 2006 Share Posted August 3, 2006 how restrictive is that though? depends how quiet you want it to be? why do you care how restrictive it is on the street anyway? its not like you need all the power, nor should you need it.

MANWHORE Posted August 3, 2006 Share Posted August 3, 2006 noise and restriction are proportionate. I don't care what anyone says about their quiet system that doesn't cause a restriction. Basically, it will be more restrictive if you make it quieter. The question is HOW MUCH that restriction affects your GIVEN POWER OUTPUT. Personally, I run a straight 3" pipe. Most possible power, minimum possible restriction. BTW, I have an ecv in my car. It's very restrictive. The car feels like it accelerates about half as fast. you can watch the revs climb if you stamp it, and it is really choking. Whereas, in first, if I normally floor it, the rev needle just smacks straight up to the red. Regarding the rear plug in silencer (buttplug), i find mine to be quite restrictive like the ecv. Regarding the centre muffler - refer to my first point regarding noise and restriction.

MANWHORE Posted August 3, 2006 Share Posted August 3, 2006 btw, ecv is not 200 firstly, it's 300$. you need the 81mm version if you have a 3" exhaust. Then you need an exhaust shop to cut off one of your flanges, then weld in the ecv. It's u to you whether you want to quieten it down. personally, i want it as loud as possible.

Busky2k Posted August 3, 2006 Share Posted August 3, 2006 I found that the ECV in cars have a modest effect. It certianly doesnt go from ear splitting to stock like. I'd be looking at getting mufflers first and use the ECV to 'top it off'.

ToF Posted August 3, 2006 Share Posted August 3, 2006 (edited) Why do you want the Blitz? The Trust Power Extreme II is very quiet but still gives off an awesome growl when you give it to it. I believe it is also 88dB alone (stock dump + front pipe) as well, so all legal.

Ryan1200 Posted August 3, 2006 Share Posted August 3, 2006 Dont waste your time with the apexi evc i hav it and had nothing but problems with it so its now wired fully open.. spend the extra cash and get yourself a legal exhaust system.. best iv seen are CES exhaust systems in brisbane.. they will hav a system in stock to suit your car and guarentee legal db's and 20+kw gain...
