apoc_reg Posted September 8, 2003 Share Posted September 8, 2003 I just received my cat replacement pipes for my MKIV NA and they look nice and unrestictive but there is no place for the sensor which goes into one of the cats to go. What does this sensor do and will I be ok not having it conected? Thanks Link to comment Share on other sites More sharing options...

Soonto_HAS_soop Posted September 8, 2003 Share Posted September 8, 2003 My TT probe got tied up out of the way. It's only a catalytic(sp) temp warning gauge, no cats = no worries! Ben.. Link to comment Share on other sites More sharing options...

apoc_reg Posted September 9, 2003 Author Share Posted September 9, 2003 Just had a look in the technical section at down pipe install and it mentions a support bracket which bolts to the cat pipe. I dont have one. does anyone know if a NON turbo should (as the article is for a TT supra)? thanks Link to comment Share on other sites More sharing options...

Scooter Posted September 9, 2003 Share Posted September 9, 2003 Apoc, could you let us know how the cars effected when this is fitted, particularly the exhaust note / volume. Cheers Link to comment Share on other sites More sharing options...

Mines the same. You sure? Is it not a HEGO sensor (lambda probe) which goes before the CATS to adjust the mixture? Link to comment Share on other sites More sharing options...
Soonto_HAS_soop Posted September 9, 2003 Share Posted September 9, 2003 The lambda is in the turbo housing at the top of the exhaust system, no where near either of the two cats. Plus I have a little warning light on the dash to show it. Ben.. Link to comment Share on other sites More sharing options...

Cheers If I can butt in, like a rampant horse... I had my cats out, and did notice a small increase in performance. Exhaust note could be described as F ing LOUD, a bit like if the exhaust pipe had been rammed into the back of your head and the hot gasses were melting your cochleas.

lust2luv Posted September 10, 2003 Share Posted September 10, 2003 Good description of a decatted SZ! I seriously doubt the lambda probe would be in the turbo housing on an NA! Link to comment Share on other sites More sharing options...
Paul Laing Posted September 10, 2003 Share Posted September 10, 2003 how much are these pipes for the NA? Are they the same as the Turbo? Paull Link to comment Share on other sites More sharing options...
Thorin Posted September 10, 2003 Share Posted September 10, 2003 Originally posted by Paul Laing how much are these pipes for the NA? Are they the same as the Turbo? Paull A little bit less I believe (as it's all one section). Think CW's are ~£280 for the NA pipe and ~£300 for the TT pair. Link to comment Share on other sites More sharing options...
