Need exhaust help anyone

[p33pss]

Bought a classic blitz exhaust off site member looking for best way to make it fit my newage sti its cat back anyone done it before

[Shambles]

Is the centre also blitz? If its just a Subaru centre then change the back box only. If its a classic centre section then you will either need a classic down pipe or cut the flange off the centre section and change the length of the pipe to suit.

Aye its blitz centre too 3" will my prodrive sprorts cat be 2.5 or 3" do u no

[Gambit]

Itll be 2.5

[scooby stu]

Im pretty sure it narrows to 2.5 to fit ok. I had a nur spec on my rb5 and it was 3 inch but narrowed to 2.5 to fit.

I think it mite be 2.5 going into 3 at backbox end and centre 3" at each end so will this not fit rest of my prodrive system do you think without welding

The length of the downpipe is different between a classic and newage. A complete classic system will fit a newage lengthwise and vice versa with newage system on a classic. The issue is when you try to use a mixture of both parts

Oh rite happy days so need get a classic downpipe to just cheers lads for help
