I suppose if you count the exhaust too then i've removed weight there with my KTEC one Yeah i still need to get the isofix bar out to be honest. Maybe, just maybe one day i might get some nice fixed buckets if i have no rear seats as i've heard recaros are quite heavy but i love them too much at the moment. They don't get uncomfortable on long journeys and they're so hugging. I just don't need the recliner ability tbh.
I would like to remove some bits of weight here and there but as i said it is a daily after all and i don't want it to become too uncomofortable or noisy haha.
When you say gutted the acoustic valve, how have you done that? did it increase induction noise at all?
Exactly, these cars are still built to a budget and with things like exhausts mild steel is cheaper and doesnt reverberate like stainless meaning its quieter. Its often heavier due to thicker gauge too.
So, I have removed all of the vacuum hosing and blanked them all with 4mm silicone blanks. Removed the solenoid from the bracket and hid it in the airbox (kept it plugged in otherwise it will trigger an emissions light) and ditched the bracket. literally gutted the valve as in took out the flap and cut off the exterior motor so it looks like an intake trumpet. Due to the hole you are left with I wrapped it in black electrical tape. It does increase induction sound a little when flooring it which is perfect and saved half a KG. Ill get some photos.
