I have recently acquired a Maniflow 4-2-1 manifold with a 200 cell 'sports' cat (pic)
I am currently running a fairly standard looking manifold which has no pre-cat (pic)
Will be fitting the Maniflow shortly.
I'm wondering what differences it will make to the power and torque delivery.
I have a 2005 R53, currently it is configured thus:
17% KAVS pulley
Required colder plugs
Standard-ish manifold with cat, but no pre-cat
Orranje Stealth CAI
Non resonated cat back Milltek
Airtec Intercooler
JCW ‘Blue’ 380cc injectors
Dyno-ed April this year - mainly to check out the air/fuel ratios (AFRs), how rich or lean it was running.
211.8 bhp @ 6,250
200.8 lb-ft torque @ 4,100
