hi need a littel advice have recently had a new millteck stainless system fitted to my vrs and high flow down pipe and decat. however since it has been fitted have noticed a strange noice when i let off the throtle sounds like a loud pigoen in ma engine bay:rofl:. lol but didnt do this before , have ask amd essex wher the system is fitted they say tha it can make the turbo noiser. just need to no if any 1 has found this problem at all .:confused:

Yeah, since I had my decat it sucks and whistles like heck.

VROOOOOOOM [off gas] woooooo Yep, mine does it. Don't worry.

thanks guys that will stop me worryin , another question what sort of bhp increase dose the system give ya ?????

Well my car ran 145bhp 239lb ft on the rollers with a decat, cat back system, pd160 intake and pipercross panel filter.

Its not much how much raw power you gain but the decat certainly makes the car feel less restricted especially at higher revs which it continues to pull into.

doesnt help the bhp that much just helps get rid of the gases quicker

a cat back system retains the cat..

He got muddled up i'd say /\

i thought decat was bad for a standard turbo?

is it actually worth doing?

it's bad for the standard turbo with a remap. On the standard map it'll be fine, slightly louder and a lot less restrictive.
