Peak 370

I think Horshams up-rev remap and 2 Cosworth filters may be the answer.

Y pipe? What's that?

Like I said at the start I don't want to waste money that I will never see come sale time; it is all about keeping it cheap.

Oh right, high flow cats. I think I'd rather de-cat, if I can get through the mot!

Have they got 4 cats, maybe delete 2?

Any downside to de-cat...after all is going to be £500 cheaper!

Berks HFCs are what exactly?

I have just bought a 2011 370Z, a very nice fully optioned one I got at a great price. My previous 6 sporty cars were all turbocharged and easily tuned but what about the 370Z, can anything worthwhile be gained without spending thousands I will never see again come selling time?

A re-map maybe? If so by who? Who's best?

Air filters? Is it really worth spending £120 for the 2 needed compared to the stock ones?

I hear about Y pipes? What's the deal there and what exhaust mods could I make without big bucks or failing the MOT?

Thanks for any advice.
