oh and dont drive too long with the steel wool in there, eventually it will start to burn as the cat get quite hot and the tester will know whats up as you he'll be able to smell it.

lol steel wool, just borrow a stock header
or get an exhaust shop to fab up a flange with like a 1" opening and jam it between the exhaust and cat
That would be an interesting experience when the tester is revving the engine at 6250rpm for the test!Quote:

Tried the steel wool still failed ..
It's all engine noise.
Anygot a stock header ??
Engine noise shouldnt be that loud as the test is about 1m from the rear of the car...if their test equipment is picking up engine noise from that distance with a closed bonnet then there is something wrong with your engine.
Im surprised steel wool didnt do the trick, i dropped my old prelude's reading 4db using steel wool. Did you use quite a bit of it and stuff it in there?
Actually another thing, what RPM are they testing it at?
Maybe if you mentioned your location...
I'm buying one of these in a few weeks time:

THAT will solve your problem.
Ive got the Varex muffler system, and if you are caught driving with the flange open, and it fails the test, you will get fined as though it is a normal non-flanged muffler. That Apexi Flange will probably be harder for the cops to find though..Quote:

I dont believe so. When the butterfly valve closes, the aim isnt to air seal the muffler.. its has a bypass where the exhaust gas travels up and down the muffler length a couple of times, like your stock muffler, and then passes out through the end of the muffler..Quote:
