hello,
i've just fitted de-cat down pipeto my99 uk turbo.the thing is it is now making a funny noise.i can hear the turbo whistling as i come onto boost but it is like a whistling stutter.if you know what i mean. i also have the heat shield rattle but i will sort that it is just this stuttering whistle i am worried about.

cheers for any advice

Lee

 

If its a slightly raspy whistle its normal.
I thought mine sounded odd as it was coming on boost.
Its just down to thinner walls of the decat.

 

cheers mate, was just abit unsure.are you supposed to hear the whistle outside of the car?onder2:
i am going to post the k/link first thing in morning + cheque.
also be in touch about the gauges fitting, may be able to come to you.

Its ok Lee,they sound a bit strange.
Sound brill when more boost is running.
Whatever suits you.
