Anyone done a cat back system on 2.2 Puma

Hi Guys,

Has anyone done/fitted a Cat back system on a 2.2 Puma yeat as wanting to know if you get a nice sound difference and any power gains but at the same time does not mess the engine up etc?

You can go completely straight through if you wanted but of course now you need the CAT present.
Alive do a CAT back system I think, you can get sooprts cats too but they are seriously pricey.

I'm confused

there is no cat on the 2.2 , only the DPF . Iv taken off the stupidly heavy no use for anything mid box AND the end small box . It's a major job taking off the DPF at the engine but what's the point ? It's only gona fail it's MOT
I have a slightly better performance with both boxes off and won't be touching the DPF .

Yeh mate probs the same thing but the cats were all easyily taken off midway along the exhaust . There's no way your gona get through emotions with straight through on the 2.2 . Even if taken off its then gonna haf to go to BAS to have the ECU jiggered about wi . A big hastle when you could be better to have it have BAS wave his majic wand on it easy .

IMHO, mucking around with the exhaust system on a Puma is not going to provide much, if any power gain.
However, I'd be interested to see a before & after dyno figure, stock exhaust against cat / middle muffler removed?
