I wanted to start a fresh thread dedicated to the Xforce dual catback exhaust, with 2.5" DIA pipes with an X section. There are some other threads out there mentioning this Xforce company, and the best one was for an ISF.

Therefore, this should serve as an current update as I've just installed the Xforce catback system for my 2012 RWD IS350.
Backstory: I was considering the PTS Joe Z, loved how it sounded in a few videos, but it was expensive. I found the Xforce as the similarly engineered and much more affordable catback (piping very similar). I got mine for ~$606 with tax on SummitRacing. I couldn't find any videos of this specific exhaust for the IS350. I took the gamble and I love it.

My verdict: Bear in mind this is my first aftermarket exhaust, but I consider it worth every penny.
It isn't loud when idle, cold start is nice and low/good tone, no obnoxious tones and not super loud when revving to max RPMS, it just sounds wonderful. A clean sounding exhaust. I had it installed at a local shop for $200 (wickedwrench), just in case modifications had to be made but it bolted up just as supposed so, only mod was needing to modify (cut/weld) the muffler mounts.
- Drone-there is a low drone when enough throttle is given in the 1.5-3k range, mostly if you are in high gears on the freeway and give it a bit of throttle to go faster, it gets pretty loud. This is easily mitigated by snapping enough throttle to downshift to speed and then cruise.
(I do have the RR Racing ECU tune, with their intake elbow and K&N air filter - which I also recommend)

I hope this will be helpful for others!

Any other experiences? Questions? I'll have to post a video later on here, but you can see it below, and more here @troy.is350 (lG):

I would appreciate a ride along or drive by myself as I'm considering the F-Sport which as we all know is stupid expensive.
TIA

// lol disregard! Thanks OP... working now!
How would you rate Weld quality and finish? Are these thick wall pipes/mufflers meant to last?

Troyx350

Finish is good, stainless steel. Welds are acceptable, not the most beautiful but I don't doubt the welds will hold up. Really, I'd say their aren't any quality issues with the material and connections, just more of asthetic, and the muffler tips being angled kinda wonky.

I think the double-walled muffler tips will last, especially since there is an inside pipe that will burn first before the inner muffler-tip wall.

What kind of power did this result in?

I know this is a little late but I'm considering getting this.. any thoughts 3 years later? How has it held up?

Here is a response I just gave on this)

Have you posted a sound clip? Interested in what it sounds like. Can’t decide if I should go xforce or Ark DT-S for my car
