I had the same dilemma with my exhaust and am still trying to sort it out, wanted something which will flow and a nice tone without being overly loud. I ran street friendly Japanese exhausts in all of my daily driven imports and was after something like the HKS legal system on my old JZX100, nice note on full throttle but fairly quiet when tooting around town. Unfortunately my vehicle runs the factory rear bumper lip so limits 99% of exhausts due to the tips not fitting
Can’t really recommend the xforce, mine didn’t fit very well and was pretty loud
Sounded amazing on full noise thru the hills but was too much for daily driving IMO, got to the point I couldn’t listen to music and my kids sitting in the back regularly complained of the noise.
Had the stock mufflers adapted to suit the xforce, cut down all the noise but sounded like there was a kazoo stuck in the exhaust until the cat heats up. Ended up swapping out for an AVO unit (same as LibertyTragic) minus the mufflers, with the plan of fitting some MY14 STI mufflers….but had some issues with fitment with the factory bumper rear lip
