CNT Racing HD-9730 Header/Up Pipe Combo Fitment on 05-09 Legacy?

CNT RACING V4 08-14 SUBARU WRX AND 04-2018 STI EQUAL LENGTH HEADER WITH UP PIPE

It doesn't say that it fits the Legacys like the CNT Racing V3 header does. Is it because of the up pipe? Is there any reason why the V4 header/up pipe combo wouldn't fit on an 05-09 Legacy if it fits an 08-14 WRX?

Thanks a lot in advance.

I called CNT Racing today and was told that it will not fit 05-09 Legacys.

Anyone on the forum who has any experience with fitting this on a Legacy?

Anyone on the forum who can advise as to why this wouldn't fit a Legacy?

Just taking a guess after looking at the pics side by side it looks like an oil cooler interference issue. Maybe someone will chime in with a definitive answer though.

I think you might be right looking at the angles, but does the WRX not have an oil cooler there as well?

Why not go with v3 or one from 1320 Performance ELH?

Interesting.

I like the idea of an equal length header / up pipe combo or at least having the two made by the same company for better confidence with fitment without spending 3-5x as much on GS/Cobb/whatever. I have a CNT downpipe and I'm pleased with it so I went back to CNT looking for a header / up pipe and found this.

It looks like 1320 doesn't make an up pipe to go with their header and CNT doesn't sell an up pipe separately to go with the V3 header.
