Anyone with the ARK Exhaust experiencing a jolt when you're slowing down? I get a noticeable push forward (back pressure?) when I slow down and it down shifts the car.

Not sure if this is normal as this is my first full catback exhaust system.

That's your transmission. I'm not sure if the auto rev match works on D (auto) mode since I also get the forward jerking motion, but on M (manual) mode, and I'm high (above 3k) up in rev, it matches almost perfectly.

Are you referring to the "pop" sound when you downshift, like when you slow down going from 3rd to 2nd? If you are, here's a thread that might help :/ https://www.clublexus.com/forums/per...ackfire-2.html

I don't really hear a popping noise. I usually drive in D mode. I'm experiencing a small nudge when I'm braking. It is similar to when RPMs jump back up in manual as you're shifting to a lower gear. It just feels harsher than the stock exhaust, which I felt very little, if any, jolt.

Yeah I was wondering what that noise was when I downshift but now I know I wasn't the only one that notices
