March 23, 200818 yr comment_234738 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! Report

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 Report

April 3, 200818 yr Author comment_237102 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 Report
April 4, 200818 yr comment_237258 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 Report
