hi all,

OK, I want to go decat..current setup is below.

HEADER:GT spec Gen2 headers
UP PIPE: GT spec Gen2
Downpipe: H&S high flow sports cat to 2.5"
Centre pipe(with o2 sensor in it): stock(i think) 2.5" to 2.5"
Tail: blitz nur spec R.

as far as I understand the nur spec starts at 2.5 to match the stock exhaust setup. my centre pipe mount that goes to the gearbox has snapped so i want to get rid of this..

so, my options are, 2.5" decat to the stock centre pipe (replaced for a new one with a new mount) or I have seen a 3" downpipe that replaces both the downpipe and centre section but then it wouldnt fit on the nur spec R.

Ideally I want a 3" all the way through but want to keep as much of the nur spec as possible..i think its in 2 pieces so can I keep the back box and replace the reducer section? any suggestions on what pipes to go for?

Thanks for any help in advance.
