Ph2 172 running a ph1 cat

[cs_dave]

Is there any reason that my ph2 172 would have a ph1 cat as ive found out today lol. Its getting decated but intrests me as 2 y

The cats are the main difference of mixing exhausts?

Phase 1 manifold?

Phase 1 cats are shorter if single lambda so I guess this is a twin lambda one.

People used to swap to them cos they flow better but I'd be surprised if it was a noticeable difference.

 

[cs_dave]

Only ad a quick look will see if its a twin lambda. Are the ph1 and ph2 manifolds the same. Ive never done a ph1 lol

Yeah the manifolds are the same.

I thought there was a difference in flow? Phase 1 being better?

That will do as i have a pms decat system to put on so will just sell the cat lol

I was told that the cells of a Ph1 were on par with a sports cat cell .
That's the only reason I see it's fitted , or because it was cheaper .
