Recently I've been calculating the costs and finalizing the logistics for an RB26DETT swap I'm going to do into my 260Z. I understand to some people this alone may be sacrilegious, but to each, his own. I have everything else for the swap figured out except for my exhaust. Obviously, I am going to need a custom exhaust, so I'm looking for suggestions on mufflers and resonators that can give me a good F1 style sound, but, I also don't want it to be earsplittingly loud. I do understand that raising the rpm's would be the best way to do this, which I plan on doing eventually, once I have the money to rebuild the engine with aftermarket internals. But, for now, I would like to find a muffler or resonator that could provide me with that high pitched sound. Thanks for the help!
