Exhaust loudness dropped dramatically? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

1) I would check all the clamps, gaskets and the pipes themselves on the exhaust system first maybe have blown something out of there
2) Have someone else listen to your car so if its loud for them or multiple people its probably just sensory adaptation

I took off the muffler and ran it straight out the stock front pipe needless to say it was stupid loud but it all sounded good (did not remove axleback). So I reinstalled the muffler and it lost all rumble and was very quiet and my buddy said it sounded a lot quieter then it used to as well. My brother said the same thing.

Just lift the car up to and rev the engine around 2500RPM to check for leaking exhaust. I've had my Borla UEL on for a year and it did not lose its loudness at all before I changed to Tomei EL.

An exhaust leak would not make the car more quiet.

I love the part where you end it with "Please help".

Sure it would! All the decibel fairies would get away!

My vote is for something stuck in the muffler. If something was stuffed inside you would be able to see it with a flashlight right?

If the exhaust was blocked so much that is makes the car quieter it would be throwing CELs like crazy by now or stopped running completely.
Exhaust has to get out as badly as air needs to get in.

Now I don't know a lot about exhaust but doesn't the muffler have done kind of "packing" inside? Could that have settled or come loose?

Usually that will make it louder. Or if it blocks the flow too much start throwing codes.
Not an impossibility though.

Did you find a solution? I’m experiencing similar issue, and don’t even know where to start
