Hi guys first time posting so be gentle lol.

I'm the proud owner of a nighthawk black 2001 DC2 type r which I've now owned for a week it has 87,000 on the clock paid $17,500. I have a couple of questions.

1) is it worth getting a set of JDM headers? Where could I get some? I don't want an exhaust and am not tracking the car or modifying it.

2) is there a way to widen the bolsters on the recaros? I'm a big guy and there a bit tight.. I'm not fat just 6 foot 2 and 100kg lol. Or can anyone recommend some seats? It surprisingly has more head room than my vtir prelude

3) do all type r's have the little placard under the hand break with the build number?

4) what's the life expectancy of a stock type r engine if it hasn't been tracked or thrashed and full service history?

5) the old owner was using motul oil I think it is.. is it any good?

Thanks in advance!
