intake hissing?

Hey all,

I bought an ED GLi a few months back that was (is) pretty much immaculate (seriously). I got a 2.5" cat back system about a month ago, and im glad i did coz it's so much smoother to drive. However, when givin it a good rev (very occasionally of course :s6: ) it starts to hiss for about a second just before it changes gear (ie. 2nd to 3rd) and noticably drops off in power. This cannot be good for it i wouldn't think?
It's an auto, and runs a tickford installed LPG system (dont laugh, i couldnt afford to run it on ULP haha).
Where would this restriction most likely be coming from? The car is 100% stocker other than exhaust...

Thanks guys.

Re: intake hissing?

Sounds to me like it could more likely be the bands slipping in the auto, considering it happens just before a gear change.

Have you had the bonnet open and actually had a listen for it to see if you can locate it?

Re: intake hissing?

Have you checked the oil level in the auto?

oil level is a couple of mm over the full marker on the trans dipstick. I've only heard the hiss while driving, but i thought it was corresponding to the revs it was doing, not the gear change...

I've never had it stationary revvin it's tits off before, but i've put the boot into a bit while stopped and couldnt get the noise, although i thought it was because of not revving it high enough to require the same volume of air as when i revved the crap out of it going along and it hissed.

My tranny is generally smooth as silk, yet tight, so i didnt think it would be that. Trans fluid is clean, and i've never given the auto a hard time coz i've heard they're pretty weak.

thanks.

i hope that last reply made sense haha. Pretty confusing when i read it back to myself.

Anyways i just tried it, and it does do it while stationary and revving the crap out of it momentarily also (i warmed it up for 10 min first).

Tried to get little bro to listen, and he said he couldnt tell where it came from coz the loud exhaust makes it hard if you arent used to the noise it makes.
