Quietening down a 1.6td

[rumbling_caddy]

   I have a caddy w/ a 1.6TD.  Currently is has the OEM hood pad plus I dynamated the hood.  I also put a rubber seal all the way around the edge of the hood.  Even with 2 muffler in series my caddy is still fairly loud.
I do have one of those TDI sound shield that go under the engine but haven't installed it yet.  Perhaps I can get to that this weekend on report back whether it makes a big difference or not.

They sell an OEM MK2 version on german ebay here:

The lower engine bay cover may have also come stock on ECOdiesel Jettas in the US.

I have seen a few belly pans on Canadian mk2 TDs

Park on some grass & get out & listen to the difference. The reflected noise is unreal.

The TDI belly pan is an acoustical thing of beauty... it looks like the wall of a miniature recording studio,  with varied sizes and heights of dense acoustic foam cubes.  Between that and the top foam-lined engine cover there's a huge attenuation in sound.

Where does it mount to? I wonder how much work it would be to put one on a mk2...

[Vincent Waldon]

The TDI has two splash guards on the sides of the undercarriage as well... contoured to fit against the frame and then flat to provide a surface to mount the belly pan to.  Dunno how well they'd fit on a non-MK4 chassis... one might be able to snag a set from a junkyard as an experiment?

I have a newly built 1.6td that broke in and at idle and low criuse it seems loud as you can hear the clatter (especially now a 0°C or lower).  Under boost it quiets down nicely and a cruise you can't hear any clatter (about 2900 rpm) with good power.  I'm just concerned abit with the sound a low cruise.  Is this the way it should be?  Just wondering..

Does it sound like its powered by a gang of skeleton flamenco dancers?

What about mufflers? I've been looking at options to replace my cherry bomb to reduce highway drone, any thoughts? Magna flow has a SS option that'll fit nicely but I don't think they are particurly interested in quiet vs performance & sound.

blackdogvan - I have a magnaflow ss muffler I bought from summit that is striaght through ($70).  I think it's quiet unless your full on max boost gets a bit louder.  I like the fact it's straight through.  With 2.5 dia, I'm sure there's not much backpressure at all. (on the 96 golf with 1.6td)

I had a Mangaflow on my gasser, absolutely loved the sound.  I've got a Grant on this one, also sounds fantastic.  I've got a heck of a lot more noise coming from under the hood than I do from the tailpipe either way...

Me too........I've got a thrush muffler.

Smear 'Canesten' on it then; also good for Athelete's Foot

I wonder about mufflers with f glass in them over time with soot build up...
