thanks for the info
i have been pestering people for some time now can anyone clear this up,
i hava UKDM integra Type R
mods:
AEM long arm intake
SS tein Springs
Mangoose Cat back system
i want to get a manifold and high flow cat, but am unsure what size i will need to get as the ukdm standard manifold s 2.25",
if i fit a 2.5" manifold and high flow car or decat (change for mot) will it marry up to my mongoose system, as i am not sure if it is 2.25" or 2.5", no point getting a 2.5 manifold if it will have to be converted to fit a 2.25" cat back system.
any advice would be great,
just found my exhaust it is 2.25" (57mm)
what shall i do, is there much power difference between a 2.5 and 2.25 ststem?
thanks folks
