that's fairly heavy.

the smb one i have is smaller and definitely at least 1-2 kilos lighter than the oem one.

I belive stock is around the 9.5 kg mark.

I dont think there is a huge performance gain everything on my car (NB8B) is stock excpet the N power muffler and it only made 80 rw kw.

Well, I went and visited James this morning and got one,fitted it up, and love it. Great note,quite deep, but it lets you know its there.Can't say I've got more power, or response, but it sounds great and thats what counts. Thanks all for your help and suggestions.

you'd be lucky to get 5kw.

Well during vic dyno day, Stevesports car made 10 rwkw more than Wun. The main difference is he has mid pipe with highflow cat and cheap pod filter. So 10 rwkw for exhaust mod is very much achievable, rear muffler prob just make around 2-3 rwkw, what's important to invest in high Flow cat when you do your mid pipe.

I believe or my theory is:

muffler alone is 3 kw.

a pod alone is like 3 kw

but a pod + muffler + cat is like + 10 kw.

With the cheap pod filter, was it from the stock pipes? If the intake was on the hot side, was there heatshielding?

The power difference between these cars on the dyno is not always because of mods, what about if they have worn spark plugs and leads or one car has 200,000km on it. Some motors are also just freaks.
