HM headers and Lukey exhaust?

KWAWD, is yours the KW GTVi AWD or the KL Ei AWD? If former, then you already have the straight through muffler as fitted to the Sports/VRX and other GTV/i Veradas. When you overtake, do you just kick down or use the tippy to shift down a couple of gears? If former then if you normally drive sedately then it wont respond very quickly as it learns your driving behaviour (better to use the tippy). I use the tippy all the time and do not have overtaking issues (even with wife, 2 kids, boot full of stuff) on the highway. Bear in mind, I also have the 380 cams and SKR tune as well as modified intake to feed in cold air from outside (similar to the NZ CAI snorkel) as well as a 200CPSI metal cat.

I've got the KL AWD. (Apologies about my handle here which is misleading). I don't think it comes with the EI designation, it's just the AWD?
I just use the auto in, er, auto mode, mostly. But overtaking feels less effortless than my KH, as if its holding back somehow.
I gotta say, the KL kicks down at the right times and all and I'm not necessarily flooring it at top speed when I get this feeling of holding back. It feels like its revving harder sometimes than the KH would be in the same scenario. I think it's noisier than the KH which probably gives me that impression, I dk. The KH can be slow to overtake at high speed because it won't always kick down, but it never felt like it was being held back, always felt free flowing. The KL just feels like its not breathing easily or something, it's hard to explain. Basically the car is heavier than the KH and naturally noisier given the drive train, so I put this feeling of "holding back" down to that, a perception thing. It's got to work harder to deliver the same performance as the KH, so rev harder and sound noisier right?
You're probably right about using the tippy, i do drive fairly sedately sedately most of the time. I'll try it, but I think any simple mod that improves performance is worth a go.
Sounds like ur car is quite a bit different to mine with those mods tho.
