Clown Posted March 23, 2008 Report Share Posted March 23, 2008 If you have a flange join somewhere, make a plate with about 5-6 holes at approx. 8mm in dia. in it. That worked on a mates skyline. It will give a little bit more back pressure but its only for the epa test. Here's a bad effort for a diagram but I think you'll get the idea LB Aparrently thats not entirely legal, but hey the tyre place lets it pass! Gotta be carefull that you don't get done again for noise pollution soon after tgetting it cleared its a BIG BIG fine. Its kinda crap that you have to go through the hassle if the car is legal like my mr2 was! Good luck with it dude! Quote Link to comment Share on other sites More sharing options...

Pitty you had to get a bigger muffler. Hopefully you got a flange join on it so you can put your old one back on. Spewin that the flange plate didn't work. I'm thinkin of putting one of those VariFlow butterfly thingy's on mine. LB Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted April 2, 2008 Report Share Posted April 2, 2008 those variable things are not legal if their full opened state is louder than 90db Quote Link to comment Share on other sites More sharing options...
butty Posted April 3, 2008 Author Report Share Posted April 3, 2008 i put my original exhaust back on no longer then 4 min after the test with the quiet one... faxed away the paper work today...so i'm all sweet till they ping me again..but i did get a flange welded on just before the muffle so its easly interchangable..... the quiet one was about twice as long as my loud one...lol had it go on diagnally just to fit it haha Quote Link to comment Share on other sites More sharing options...
webers4x48 Posted April 4, 2008 Report Share Posted April 4, 2008 those variable things are not legal if their full opened state is louder than 90db My exhaust isn't legal any way so any improvement is good. I just don't want to go backwards by putting a smaller exhaust on it and then find out that I have to put the big 1 back on when I turbo it. i put my original exhaust back on no longer then 4 min after the test with the quiet one... faxed away the paper work today...so i'm all sweet till they ping me again..but i did get a flange welded on just before the muffle so its easly interchangable..... the quiet one was about twice as long as my loud one...lol had it go on diagnally just to fit it haha I hoped you did that :abuse: LB Quote Link to comment Share on other sites More sharing options...
