exhaust clarification

[scottthurlow]

i need 100% accurate answer

i have a 2003 saxo vts and i have been told that the cat is in the manifold and in the centre section

i am 90% sure that its in the centre section but need to know for sure!!!!

[KamRacing]

centre section 100%

[scottthurlow]

cheers budd, so for exhaust system i can go with

4-2-1 mani, decat pipe, mid silencer/no box, pipe to back box

correct me if im wrong

Yes or keep your standard cat and centre pipe, then run a full length performance centrepipe. Usually works out cheaper than a decat + catback pipe.

[scottthurlow]

so keep the cat and centre pipe for mot?

and the full pipe for normal, would that be really loud?

links to parts please!

[LeeM]

just noticed that
this is the vts mani and cat deisgn and centre section. same for all vts's except for the addition of a second lambda sensor in the mk2

so what would i need to decat the car the cheapest but easy enough to change for mot purposes!

[LeeM]

a decat pipe to replace number 11 in the first pic, thats the cat.

[scottthurlow]

so wats the sports centre pipe that would eliminate me not needing the decat pipe???

[LeeM]

that would go from the manifold to the backbox, 1 piece that removes the cat and silencer.

Its one long pipe instead of a decat pipe plus middle section. Makes it easier come refitting CAT for MOT and stuff.

[scottthurlow]

so the one long pipe is easier to change than the decat pipe ?? i though it would of been easier the decat pipe been changed?

[LeeM]

id rather change a decat pipe than a full length race pipe but thats just me lol. however if i was decatting id remove the silencer too.

[scottthurlow]

i probs will remove the silencer and go the decat pipe route! but dnt want massive loud system

[LeeM]

i had a sportex straight through with an ashley backbox on a standard vts manifold, it was one of the loudest cars ive ever heard

[scottthurlow]

i dnt want it that loud so would they need to put 1 mid box in or a bigger backbox???

[LeeM]

well i didnt think a cat made much difference, but ive put my btb on my mates vtr which has the cat in the mani and its its sooooo much quieter
