How to muffle exhaust (to pass the EPA test)

[RFish]

hey guys

The other week my car got picked up for being to loud, it was 4db over the limit, it's a Vz sv6 with a twin 2 1/4 system.

Any suggestions on how to quiet it down just for the test, read stuff about steel wool in the exhaust cuts the sound back but i honestly have no idea?

I only want a quick fix just to pass the test.

Cheers

Fit a couple of smaller tips with rolled in ends.

Where can I get that and how do I attach them?

Any exhaust shop can do it. Get a couple of tips that fit inside you pipes and tack weld them on, this will quieten it down.

Steel wool

Did it in my subaru years ago to quieten it down for RWC, think they check for it now though

All i can think of is to pay to get a bigger muffler or somethign on? :/

This car must sound like the loudest wet fart imaginable.

This will work, it would reduce the noise by about 2 or 3db approx. install them just before the pipe joins on to the rear mufflers.

in the past i have used rolled up chicken wire in the pipes , passed the noise test no worries drive home and pulled it out never hassled again in that car , last one was in my VL running a 3 " system one muffler and a ressy out the back once again letter arrived saying a police officer observed my car and believed to have a defect or loud exhaust , so pulled out the chicken wire rolled it up dropped the pipe after the cat and fitted the wire , went for the test passed with a reading of
84 db , drive home removed wire no more hassle over the next three years .
Also i have used the baffles in the rear exhaust flanges of late model ve's 6 and 8 , just a plate of steel 1.0mm thick with holes drilled thru
