ETS quiet exhaust and a test pipe... Too loud. Ideas?
My current exhaust set up is too loud. I have two kids and really need to quiet the car down a bit. It's hard to hold a conversation in the car and the back seat is too loud for the kids. I had an EVO 8 with buschur exhaust and a magnaflow muffler running a down pipe and test pipe previously... my X is significantly louder.
Currently I have an Ultimate Racing down pipe and test pipe mated to an ETS V2 Quiet Exhaust. Honestly I thought this set up would be a "quiet" option, but it is really loud.
I'm considering the UR mini muffler test pipe, but I'm not sure how much of a difference that will make. Has anyone switched from a TP to this? Is it barely noticeable or does it make a significant difference? Searching on here I found that people like the UR mini muffler test pipe, but haven't quite got my question answered. Anyone with my set up that has switched??
I don't really want to switch to a high flow cat, but will if thats what it takes. Just don't want to waste 300 bucks on a mini muffler if its not going to be a noticeable change.
My kids thank you for any help!!!!!

The test pipe does make a decent difference, if the quiet system is too loud the only real option you have is adding a HFC to quiet down the system. The test pipe w/ resonator does not work all that well, it does change the note, but it doesn't quiet it down much. The 3.0" diameter resonator takes effect around 5000rpm+ where a 2.5" seems to take place around the 2500rpm range. It's all based on sound waves and resonance frequency. The HFC does add a restriction into the system and changes the note.

Have you tried putting the resonator right in front of the rear axle? As you know (so I'm saying this for others, not to insult you), the effects of a resonator depends not only on size and such, but also on location. From what I can tell from spending hours looking at the designs of Evo X exhausts, the quiet ones either are small (which will push back the optimal location to the point of being in the actual muffler, so that works) or have a resonator before the rear axle. It has always surprised me that your system, designed to be quiet but also 3", doesn't have a resonator in front of the rear axle.

I always thought the ETS quiet was loud even for a quiet exhaust. I do like the sound though.
For quiet I still prefer my T1R exhaust. Full 3" with resonated testpipe.
It's quiet compare to the Buschur, ETS, and UR exhaust I heard.
Here is a thread with pics of how the T1R exhaust is designed. Super quiet and only aggressive at WOT. Good for a daily.
