I sold my 370ZN back to Nissan Mill Hill last week but they wanted the original exhaust and cats back on it hence why these aftermarket parts are up for sale. The Cobra has done 13k miles, Berk HFC 10k miles - I want £400 for them and £700 for the Cobra (inc Y-Pipe). Discounts of £75 and £250, respectively. These are both rare as rocking horse organ donors and hold their value very well. Discounted to £1000 for the pair (and OMG what a special combo they are). All nuts, bolts & gaskets included.
Note that the Cobra is probably the best-fitting aftermarket exhaust for the Nismo extended rear valance and fits with perfect alignment.
I'm based in Putney, SW London. Willing to travel a moderate distance to deliver if paid for in advance.
