Going to decat - bit of pipe or £300 decat pipe?

[BennoGTi]

Im gonna decat my car hopefully within the next few weeks

Just wondering, if anyone has done it before on the GTi

What did you go for, cut the cat out and weld in new bit of pipe or the £300 decat pipe from the likes of Miltek, Blueflame ect?

Is there actually any noticable benefit of forking out £00ish over £10 for a bit of 2.5" pipe?

Thanks for any advice

the decat pipe is a bolt in section and will have locations to house your lamda sensors which will need mapping out if you do not want a engine light on

and if you go this route your standard cat remains untouched so could always be replaced for mot time or resale time

cut up your original cat and no comeback

Ahh rite, that explains the price then

Thanks for the info, probably best going with a miltek/bluegflame decat to save the sensor hastle and MOT time ect

Cheers dude




So anyone know of any good decat pipes, from the likes of Miltek, Blueflame.. demon tweeks ect?

Links would also be very helpful.. do I need the 63mm or 76mm one? For a 2007 GTi

Sounds a much better (cheaper) option!

How did you get around the emmissions light coming on mate?

[zedzo]

never came up on mine or the others weve tried it . gti mite be different tho.

[oliverpologti]

emission light came on straight away on my Gti after i drove off then when i got it mapped i got them to map the warning light out for it being decatd

[RoSonic]

Is there only the emission light coming up or does the car go into limp mode also?

[oliverpologti]

mine just emissions light came on didnt go into limp mode

Did they map out just that sensor or basically everything do do with the emissions light? Like a fancy way of taking out the bulb?

Can any mappers do this? Im getting a REVO map soon from Intelligent Tuning in North Wales, they should be able to surely?

[oliverpologti]

just basically remapped the sensor so it would accept higher emmissions but not read too high so the senor and system would give me warnings if there were other probs jason at more-bhp did mine for me

[BennoGTi]

Is yours a custom one from a shop or a standard one from the likes of Blueflame ect?

Anyone know if I need the 63mm or the 76mm?

[oliverpologti]

mine was the blue flame one mine was 73mm but i had full blu flame 73 mm system smaller one will be one you need unless your going for full blu flame 73 mm system
