Liam Posted October 18, 2002 Posted October 18, 2002 Anyone have ideas on how to pass the noise test. My Pinto engined car on 45's failed (103). It is fitted with the 5 1/2 inch dia. silencer. Westfield suggest welding a baffle in the form of a large washer inside the pipe but that sounds a bit drastic, won't do much for the stainless steel. Liam Quote
Mark Stanton Posted October 18, 2002 Posted October 18, 2002 Treat yourself to a larger diameter (only slightly) re-packable stainless steel silencer Quote
Andrew Posted October 18, 2002 Posted October 18, 2002 What about using"gun-gum" or something similar to stick a washer in temporarily, then dig it out after the test? You could put it in the end of the silencer, and hide it with the curved tailpipe. I've also had a Pinto engined car tested earlier in the year, the two blokes that did it, had a bit of a whisper to each other, then declared it "fine", I've a feeling it too, was marginally over the limit but they let it go.

Phssthpok Posted October 19, 2002 Posted October 19, 2002 Undo your "silencer" clamps, rotate the silencer so it exits towards the ground and tighten up the clamps. The ground acts as a baffle and dramatically reduces the noise. When the bureaucratic fools have finished their testing return your silencer to its original position; preferably while they're watching. Quote
Liam Posted October 21, 2002 Author Posted October 21, 2002 Thanks all. Any suggestions on repackable silencers - what? where? cost? unforeseen snags (they always seem to be present)?Liam Quote
