Not sure you mean shifting between gears or the feel of the shifter. The shifter feel will improve with upgraded TiC shift bushings.

Seriously I did every upgrade possible to make the stock wrx 6sp shift better, nothing really did much.. worst manual shifter in my life... I hate the cable shifters.. I did an Sti swap.. OMG no comparison at all, the car went from ok to drive to amazing and fun.. and no more weird 2 - 3rd weird rev spot.. too low or too high feel... I know that is a more involved upgrade, but do keep it on your radar if you hate the stock shifter as I did..

Someone mentioned after replacing the trans mount and the cross member bushing, shifting from first to second is smoother and easier also downshift back to first from second while the car still rolling, they claim it is due to less of the transmission movement from the upgrade.

But my car don't seem to have those issue before I did this upgrade anyway. So I was just pointing out those "better shifting thought/ feel" don't really apply to me.

Here is the link for a quick clip just made showing the before and after.

Interesting, the amount of movement is pretty much the same (OEM and Group N) in video link clip below, just slightly different less with the group N, but I guess that done the trick to prevent the pipe hitting the transmission mount sub frame.

Thanks everyone's input, super happy that the J-pipe hitting sub frame issue is now resolved.

In addition, I have made a clip for my diff movement after the installation as well, but unfortunately it is not a before and after comparison.

Edit:
After two days of learning this new setup. I found that during stop light, it vibrate a little more than it was.
Pretty much that's the only noticeable difference from OEM to Group N in terms of NVH.

Bringing this up from the dead for anyone searching out j-pipe issues.

I had a GS catted j-pipe installed on my 2015 WRX with minimal miles. A well known Subaru performance shop in Maryland did all the work (including tuning). I had noticed a noise in reverse and on downshifts coming from front drivers side of vehicle. Took car back in, and it was the j-pipe bracket rubbing the subframe bolt? I didnít see it, but this is what I was told (I donít have the resources to do my own work at my house). The mechanic said the bracket was t-slotted and it worked itself out and was rubbing, so they did some basic fab work and I no longer have the issue.

My symptoms were what sounded like a thud or a clunk on downshifts and reverse. It was due to the j pipe rubbing something, very similar to the original poster. I donít think itís a GrimmSpeed design flaw, but good for people so speak up when they encounter the same issue.

Once again, I know this thread is old but I researched it like a madman before taking to my mechanic- thought anything from pitch stop, to strut top hat, to the downpipe rubbing a heatshield. Instead of was just the stupid bracket rubbing something. So for anyone else searching with a 2015+ and a grimmspeed pipe, check your bracket!!

My brothers 17 wrx does the same thing with the grimmspeed j pipe. Rubs against the transmission bracket. I loosened the bolt for the bracket on the j pipe and moved it as far as I could and it doesn't rub for now. Guess we'll see if it moves again. The only solution that would be easy enough would be the dent the j pipe in a little or grind the corner of the trans bracket itself. Anyone else come up with other ideas?

Having something similar. Get a clunk on downshift into second, only when I downshift hard though. Everything is torqued to spec, not seeming to hit the transmission mount. Making me crazy not being able to drive the car. Definitely something hitting, just for the life of me can't find it. Double checked my work on three separate occasions.

dremel the offending bolt. And reposition the pipe on the bracket to create some additional room,
