Today when I drove my ITS, I had it in Sport+. After driving for maybe about 10'ish miles or so, in local city streets and highway, I noticed that at no time, was there any exhaust "Pops" occurring. I had plenty of situations that should have produced them, such as downshift decelerations and/or clutch press engine falloffs.
Normally this not only opens the exhaust for the more audile notes, it generally will exhibit the exhaust "Pops". I understand that the system won't do it immediately. It seems to require the entire system warm up a bit before this behavior is exhibited. I also understand that not everyone prefers these noises, citing them as "immature". I tried adopting that mindsight myself to just run the exhaust in Sport. Unfortunately, I seem to really enjoy the Pops and therefore run Sport+ and/or Individual mode where I have the Engine set to Sport+ mode.
This is the first time since ownership I've experience this issue. Mine's a 2025 model and I've had it for about 1 year now.
One thing to note is that I recently replaced the OEM air filter with a K&N drop in filter (did not change to a Cold Air Intake, just replacement filter in standard airbox). I'm sure many may take issue with that choice as I've noticed in the past using those filters as replacements can be controversial and contestable. I have had years of success and observed reliability with most of my other vehicles running either drop-ins or full airbox to CAI swap outs. That being said, I've been driving the car since that replacement and observing the "Pops", and therefore am somewhat skeptical as that being the cause. Of course I tossed the previous filter to swap back and confirm this.
Do I need to be concerned?
If the issue persists, am I going to have any success with the dealership service department, in explaining, them understanding, and accepting the issues as legitimate?
I only ask that prior question because past experiences with dealership service departments in general seem to have issues with models or trims that are outside the normal higher volume sold models. As an example, I had a 2005 Toyota Corolla XRS with the 2ZZ-GE. It experienced a issue the valve timing. The dealer attempted to repair, but upon receiving back, the VVTL-i system no longer worked. When I confronted them about it, they basically indicated they didn't understand this engine due to the lack exposure their department had with the engine being it was more rare than a standard model.
