I got Gibson Swept side exhaust system on my 2000 tundra 4.7L, a few months ago i notice when i drive through town i can hear my exhaust echoing off the buildings and it doesn't sound right at all, in a way it sounds like a pinging but at idle i don't hear anything only when i'm driving. I bought it about 8 years ago and put on maybe 20-30 thousand miles. I know i'v put the muffler through hell but it's still got it's deep tone when i step on it. could the muffler be toast?

could be.

Exhaust always echos off of walls doesn't it?

Bammuffler

^ that didn't take long.

yeah but i ment that when it does echo off the wall it sounds like somethings wrong with the muffler.

Where can i hear some of the bammufflers?

never mind i was youtubing it wrong

Is it a WHOMWHOMWHOMWHOMWHOM sound? That's normal around 2k RPM.

no, i really don't know how to describe it but it just doesn't sound right but after i'v watched a few youtube videos of Bam mufflers i'm thinking i might pick one of them up...who do i get a hold of to get one?

I suppose anything is possible but in this case quite unlikely. I've had some el-cheep-o mufflers installed on several of my own vehicles and the worst thing that ever happened to them was that they rusted from the inside out because I took a lot of short trips. Then, when my vehicle wouldn't pass the smog inspection, the mechanic blew up the muffler while working on the vehicle and I had to replace it. With only 20-30K miles on the Gibson it's very unlikely that it's defective already. Even my replacement mufflers coming from the muffler shop have always lasted lots longer than this.

You get them here. PM Esondidotundra.

Have you checked for holes in the muffler and piping? Exhaust leaks? They can make horrid noises. It's pretty hard to make a muffler go bad unless you live in the salt where they rot.

BAMuffler is a great muffler, surprisingly solid. Keith doesn't mess around when he makes those.

he's hiding from you. why not take your truck to a shop, have them put it up in the air, and listen to the exhaust for leaks/rattles. inspect the muff. if it is shot after all these years, take a quick pic and send it to gibson in exchange for a free replacement under warranty.

Well just a bit ago i took my truck to pick up a few things and it wasn't making any noise at all like before :confused:

Please let me know if the links worked.

I'm surprised you're having a problem, Gibson makes a solid muffler. From your original post it sounded like the louvered core rotted and blew out, but then you posted that there is no more weird sound coming from it.

If you have any other questions regarding anything related to performance on a Tundra, I should be able to help. I'm subscribed to this thread so post up or email me dirtydeedsindustries@gmail.com
