since you already have a ur dual axle back try the ams test pipe or high flow cat but that would make it louder. This is my UR catback and my neighbour complains already when I warmup my car in the winter . I took off my test pipe to be a considerate neighbour plus I also cant afford to get it tuned yet . You might want to replace the pipe between your axleback and cat converter and that would change the sound of your exhaust as well.
i have a perrin cat back and it it a nice 3 inch piping and a very very mellow tone, my wife cant even tell that i changed the exhaust, just throwing the input out there, i love it, i was looking for flow from the 3 inch over noise from the muffler,
I am currently running a MAP 02 dump with a ETS test pipe and a ETS V2 Quiet exhaust. I absolutely love the sound. Its got a really deep tone and a nice low rumble. I don't really know why ETS calls it "Quiet" cause it definitely screams under WOT.
If you have an open dump o2 housing I'd imagine that's making most of the noise during WOT, not the ETS v2 Quiet

I was referring to when I had a recirculated 02 housing. And if you're behind me you hear the exhaust, not the dump. My dad and I went on a drive earlier, I took my X and he took his STI. We swapped cars and I followed him. We did a side by side pull. My car makes more power than his does. so I was on his right side I heard the dump as we took off. Then as he pulled ahead I heard the exhaust and could no longer hear the dump
Got AMS turbo back with mini cat (50% less noise at high RPM) with magnaflow catback and am very satisfied with sound and performance but more importantly, no cops after my car even if im tuned and got 320 WHP/340WTQ
Iam happy with my Cobb exhaust. Its not too loud or too quiet. Just right. However i dont have a HFC or downpipe on so not sure how louder it would get. Lol i dont think that bad with a resonated pipe
My turbo xs with test pipe is pretty quiet, mellow with very little to no drone. Very little bends in the design looks Oem minus the tips and the price is on point.
