Ok driving with no radio on just me an the exhaust [:D]

however.... recently ive been joined by an annoying whistle that flares up as i change gear so kinda like;

1st gear .Ggggrrrrr......swwwiiiissshhhhh.....2nd gear ... GGgggrrrrr....... ssswwwwiisshh 3rd ect.....

Now it sounds like its coming from the passenger side. only thing i can think of is where i took my wire thru for the sub. (gromit behind the pollen filter)

but it hasnt always done this an the wire has been thru there for yonks!!

Some1 enlighten me?

Thanks

Yep its the R32ism hahaha

Right you might know what im talking about if i explain.

on the standard system you have a vacuum pipe that plugs into the back box area.

you take this out an plug it with sumate to do the flapper mod.

Now ive got the miltek an the vacuum pipe is still there but bunged up from when i had the flapper done. ive spoken to awesome this morning they said theyve only just came across this themselves an believe its a split in this pipe that causes the hisses coming from the manifold!! They say its nothing to worry about but id like to find it if its blowing hot fumes onto the underneath of my car haha
