Title: had my decat fitted (Y)
Post by: Jayy26 on February 04, 2015, 06:31:50 pm

had my unbranded decat fitted the other day ...and made to fit to my miltek non-res back box...

doe sound meaty when you plant it ...the only thing that concerns me is  at lower revs when the turbo comes in,it sounds like its blowing from the front somewhere..but my dad was the one who took it to the garage and is certain its not the exhaust...could it be because i have a pipercross air filter instead off a propr CDA? and that its trying to suck more air in? ill try and get a video but its sounds so faint on the video...also when i replaced my dv to the plastic one (revison d) it made a different noise ,kinda sucking in more air? so could it be this thats got louder?

sorry its not that clear but its hard to explain...

cheers

Blowing will be the exhaust. Did you replace the gasket between the turbo flange & downpipe?

No I didn't,it was done at an exhaust specialist in doncaster..and they didn't use any exhaust paste either :/ the noise is coming from the front end somewhere..
The car hasn't lost any power thought :/

I changed my gasket when i put my downpipe and decat on and it lasted about a week till the gasket some how fell apart!
Worth a check
