Rear seats out - new noises?

[Inferno]

Not really sure what section to put this in, so apologies if it's in the wrong place!

As it was easy to do, I thought I'd take the rear seats out of the car as a few people had said that you can hear the exhaust a fair bit better and there may be some weight loss benefits.

You can definately hear the (standard) exhaust much better with everything out, but I'm also hearing a reasonably loud whooshing noice, very similar to a turbo spooling up. What is this? Is it normal? My guesses are either a leaking exhaust or the fuel pump. Anyone know?

Silly question but you did put the big bolts that hold the seat brackets back in didnt you?

Yes mate!

it will be the fuel pump but its quite normal.

It sounds like the whining from the fuel sender unit.... nothing to worry about as N!CK R said.

i can hear the fuel pump whining a bit with the seats in.

Good point, but I've got to work out how to take all the rear interior side panels off first before I get to things like that!

Any difference in performance with the rear seats taken out?

Not really, I can't be bothered to weigh the stuff I took out, but I'd be very surprised if it added up to more than 20kg. After I've taken more of the inner pannels out and swapped the fat Recaros for something more focused it might be noticable - but I'm not holding my breath!
