What’s going on everyone , new to the group just purchased any first lexus ! Have a quick question I want to get out of the way. The car has a muffler delete and no catalic converters makes a sound under the car is it normal ?

 

I don't hear anything unusual.

 

If you mean the ticking noise it's probably an exhaust leak.
Since the exhaust has been modified extensively then my advice would be to get it up in the air on a ramp and check for poor fitment.
