considering buying an 05s

[rdass623]

I am considering upgrading from my 00 base box to an 05 s model. I was wondering if anyone is familiar in the differences which may be experienced, as far as the engine is concerned. will this car although a 987 still have the 986 engine setup? in essence I have heard of different air boxes, different oil filters, and exhaust for these model years. I was wondering if my exhaust from my 00 would fit on the 05, and whether the oil filter adapters are the same for the spin on filters. the 05 has a 3.2 engine rather than the 3.4 more commonly associated with the 978s models. not really a deal breaker one way or another, but the 05 with less than 30k for around 20k is really tempting.
