Exhaust Sound After Timing Belt? (3 Viewers)

[AndersN]

So I picked up my 2006 LX after getting the timing belt done and immediately noticed what I can best describe as a slight throaty exhaust sound after around 1600 rpms upon acceleration. I also notice a distinct vibration in the gas pedal as it does not seem as smooth as it used to be. On the highway the exhaust drone sound was still there when I got into the throttle. At idle it is buttery smooth and the engine does not seem low on power. Hooked it up my iCarSoft TYTII, no codes. Below is what was done:

Timing belt Kit & Thermostat
New Radiator
Heater- T's
Serpentine Belt
Air Filter

I guess the main concern is it is timing belt related. Any ideas?

Check and see if the airbox lid is secured.

Just checked, all good there

And the air hose leaving the airbox? I believe there are two connections?

And I would check to see if the hose(s) have split anywhere during removal/reinstall.

I wonder if they got the timing wrong?
