decat

Was looking into getting a full exhaust system with dummy cat from pptuning . Was wondering will it pass mot , on inspection or emissions? I have a 2006 pre dpf 2.5 AXD engine , the plate value is 0.8 , if I'm looking at the correct number . When getting stuff like this done do you need to...

My 16-year-old catalytic converter broke off from the pipe and now I'm thinking to replace it for a new cat or decat pipe, because welding this old thing is like a beating the dead horse, and Gun Gum flexiwrap will not hold much. The choice is between BM Catalysts BM80025H, Bosal 099-895, and...

I need a new exhaust - if i buy a complete new decat exhaust system will it be an MOT fail ?

Hi Folks, I am in Australia and will be back in the UK soon. I want to know if I bring my ECU out of my 2006 T5 AXE with me and have the DPF/EGR and speed limiter, if it has one, deleted from the software? I can then blank the EGR and get a DPF delete pipe and fit it when I get back. Can any...

Hi, Was wondering if anybody could offer any advice on decating my T4. My exhaust was blowing so took it to the garage and they've recommended a stainless steal decat exhaust. They said it would be better and give a little more power. Thats nice but doesn't it put your emissions through the...

Hi all :) It's approaching that time of year again, and since the last MOT I've had a SS side exit pipe from T4S RUS fitted. The garage that do bits and bobs on my van (and sort the MOT through the local station), well, they always seem to be dubious as to whether the guy at the testing...

Big thanks to Naz at Enigma (Powerflow) in Slough http://www.enigmatec.co.uk/ for fitting my Powerflow decat stainless steel exhaust. System was crafted on site and really I'm pleased with the result. Turbo spins more readily and there is a noticeable improvement in performance.

I have posted this in the Mk4 golf thread as well, but I have heard lots of people asking about de-catting their exhaust .... Have been told by 3 independent MOT'ers provided your engine is healthy, you don't need a CAT for your MOT. Check how fine (and how much of) this honeycomb is in this...

Hi I have a 2.5 tdi 1996 new shape diesel manual acv ENGINE. The exhaust section off the front pipe seems like it has just got a 150mm dia box on it on the short section then a straightish long piece to the mid box of the pipe. Its like an L shape. It has always passed its MOT and I have had...

Got around to de-cat and centre box removal today. On close examination I decided to punch out the cat ( thanks darren mk :))as it was impractical to cut it out of the system. Replaced the centre box with sleeved 60mm steel tubing. I have pics of the whole operation and can do a step by step if...
