Muffler drone and replacement

Muffler drone and replacement

Postby DanVanPDX [OP] » March 4th 2020, 4:39am

New Safari owner here. And also new van owner. Very excited to get this thing all fixed up and turned into a camper.

Around 60-65mph a serious cabin drone resonates through the van. I found some holes in my muffler could this be the problem? I’ll also be replacing subframe bushings, lifting with new shocks, and getting new tires so hopefully between all of that any vibrations or noise issues will be taken care of.

But as far as the muffler goes, is there a recommended aftermarket alternative to replace stock? Not looking for a loud or obnoxious sound just something with better performance and maybe a little bit of throaty sound.

Thanks for the help!

Holes will make a difference. For me quiet mufflers are where it's at esp driving long distances, and vans tend to amplify any sounds.

Walker makes their Quiet-Flow stainless steel muffler that is an awesome deal for a replacement https://amzn.to/3atBhwM and this should be the right gasket https://amzn.to/2wshcbu

Agreed. Also be careful with "performance aftermarket"... you may be just trading in one drone for another. V6 engines just don't sound good.

Thanks for the help guys! The Walker seems to fit the bill nicely. The most important thing for me is no interior cabin noise if possible. But yes, I am coming to learn that an 18 year old van will always have a new squeak or noise for me to search out!

Walker Quiet-Flow for the win. Sounds just like the factory muffler back when it was new.

Oh, and don't forget that for the tailpipe you will probably need/want to borrow a tailpipe embiggener from your LAPS and grab a muffler clamp to re-attach the tail pipe.

If your planning on camperizing your van then get some of that stuff they use to quiet the vehicles as it will also make it easier to cool or heat.

Try a 32 year old van like I drive. My 88 Astro is still stock, and I plan on keeping it that way. But I did go with the Walker muffler (someone on here had provided a number for) for it when it needed replacement. It's pretty quiet, which I like. I use my van for hauling stuff, so sometimes both benches are out, sometimes only 1 bench is out, and those seats when empty will rattle too. I like to think of some of the noises as the van talking to me. If you pay attention to the sounds they make, you can catch something before it gets worse.

X2 EVERYTHING above, and if I may add; make absolutely certain that all of the hangers are in good shape and also that nothing is touching the floorpan or anything else it shouldn't. A pipe that comes into contact with anything while the engine is under load will make a droning sound too sometimes.
