Icon5 Diesel de cat? - 14th November 2013, 12:50 PM

hi, have an early '06 registered mini oneD and was looking at a decat pipe. To be brutally honest im not oushed about power or torque, im purely looking for the 'cooo' sound from the turbo. I know the fact the turbo isnt huge doesnt help, but does anyone know would this give me the desireed effect? Thanks in advance!

I know I know, but moving from an old loud EP70 starlet to a quiet and sedate sounding mini.. I'm just not at that level of maturity yet im afraid!

Surely it'd be a dump valve not a decat pipe you're after if it's the chav-tastic 'whoosh' you're after.
Also, careful doing this round town. The rozzers can ticket you for noise pollution, so is it really worth 60 and a 7-day wonder?

Was always under the impression blow off valves weren't commonly available fur diesels? Something to do with gas recirculation in a Diesel engine opposed to simply being blown off in a petrol engine?

Be aware that this is getting a higher profile with government and insurers as removal of the cat makes the car 'unroadworthy' in design and use terms. Also the remap that needs to be done is seem as a performance upgrade. Whilst only emissions are currently measured at MOT, it may well be something that will be a failure soon. So, you pay your money and take your chance!

Im pretty sure if the car was fitted with a cat originally, it fails the mot if its not there at the time of test. Nothing to do with emissions.

I know this, because in the MX5 wolrd, those who had pre 93 cars could decat but those with post 93 would get an instant fail even though the emissions were still within tolerance.

Yeah I know, I've had several old toyotas, all pre 93 meaning decats have been fine. Thing about modern engines is that all te pie work contains hosts of sensors and what not, not to mention recirculating valves and the like, making doing anything with them extremely difficult unfortunately. Not even too keen on having it loud, would just like to be able to hear the turbo spooling up and letting off the excess boost, but unfortunately it seems difficult to do because of the above. Long gone are the days of a simple mechanical engines!
