underbonnet soundproofing

[strad]

has anyone removed the underbonnet sound deadening from there astra ?

is it worthwhile ?

i have a gsi bonnet but the sound proofing covers the vents so cant see much point in it

should i junk it ?

I only removed mine for one reason. Heat.

Removing it would help letting out some induction noise and lower some temps, but tbh inless you really need to then i wouldnt remove it.

I think i'll be putting mine back on soon, as ive pulled my outside air temp sensor into my bonnet so i can keep an eye on it on really warm days, seeing as weather is cooling down a bit now i think ill be putting mine back on

Mine doesn't have any as standard...lol

When/if I upgrade to a GSi bonnet, i'll be junking it to allow for some lourves to be stamped in

mines long gone lowered the under bonet tems alittle and let the vents work better without it.
can here my tb's more now too.

The sound proofing is still on my GSi and it doesnt cover the vents!!

If you want more cold air in/heat out you can take the plastic black panel of the back of the vents.

I removed both one my old Gsi my new one doesnt have vents yet but the sound proofing has been removed. Saves a bit of weight as well.

Are you not able to just cut the proofing a bit on each side to allow the GSI vents to work??

sound proofing on mine is long gone. never had it on any of my astra's, seen it catch fire soo many times i prefer to rip it out !!

genuine gsi sounds pads go around the vent like mine and sim2cool's, but im doing away with mine if any wonts it for the purists out there i also have taken out the air-deflectors out of my gsi vents
