Hi folks,

im after abit of info regarding a decat pipe?

what are my options on this? where to buy?

im also thinking about renewing the exhaust system for a slightly larger bore system, are there any off the shelf systems available? maybe or not a passat/audi system could be modded to fit?

any help regarding a decat would be a great help.

-------------------------------------------------------------------------------------------

also to add, im getting strong exhaust fume smell in the cabin, i notice it more at standstill but its still there when moving, also its more apparent with the heater on hot but not so much when on cold.

and when standing at the rear of the car the exhaust fumes have a really choking smell. the car doesnt smoke either.

thanks.

I have the same problem with the fumes being faintly noticeable in the cabin and the strong choking smell at the rear, I'd really like to know what it is too...

Mine started doing it after a new turbo and egr valve and has been the same ever since...

so far ive found -

i think i'll give this one a try - http://www.ebay.co.u...682255622??from looking at where the cat bolts to the turbo on the car im pretty sure its a 3 bolt flange as opposed to the 4 bolt type.

I have 2.5 v6 tdi custom system by SK DESIGN

From 2.25 inch gone to 2.5 inch

Pre-cat ....gone

Cat.......gone

Centre box...gone

Rear box left standard due to the less noise with it and still keeps the smoke done even thou my one gives no smoke at all

Custom systems aren't that expensive, why not find a reputable place and get one made.

True that. ..
