2017 Red Sport 400 w/ Fast Intentions lower downpipes and non-resonated cat-back exhaust.
I've also been driving in Standard mode when around town - keeps the rpms down, but also it doesn't rev match when downshifting (Sport mode), which I really don't need if I'm not getting on it.I think I'll find myself driving in Standard mode when in town. Something I never do, as I'm in Sport always. But keeping the rpms down a bit, and the quicker shifts, may be just right. We'll see. As for the gains.... they're defiantly there. 0-80mph seems much quicker.
Really? My RWD feels like it rev matches in any mode. Even in ECO mode if I'm braking and downshifting when going from 60-0, when I hit second there's a momentary acceleration.I've also been driving in Standard mode when around town - keeps the rpms down, but also it doesn't rev match when downshifting (Sport mode), which I really don't need if I'm not getting on it.
Now that the exhaust has some "bark", it becomes very obvious when the rev-match occurs. While it is obvious in Sport & Sport+ modes, I can't say I've heard the rev-match in other modes.Really?

For those with the downpipes, do you get a strong smell of fuel without the cats?
Thanks, keep us posted on any negative side effects or any difference in gas mileage either way.No, because the system still utilizes the primary cats. The DPs replace the secondary cats, which are specifically for meeting cold start emissions. Once the primaries warm up, i.e., "light off", which is pretty fast, the secondary cats are along for the ride, per se.
I've had my DPs installed for the last three days, and with over 100 miles of seat time, no check engine messages, which is expected, because the system still meets its Readiness requirements, which is what emission stations look for when they tap into the OBD-II connection. In addition, Infiniti just sent me a automated message regarding the car's health, and it was all green
Sounds nice and deep, a little bit of raspiness but that's what I love!
Put about 100 miles on mine as well over the holiday weekend, and I love it. Super deep tone with just a hint of rasp, and nice "blurble" on the rev-matching/down shifts, although haven't had an actual backfire yet.Does it "blurble or backfire" during downshifts or letting off the throttle at higher RPMs?
