Nissan 370Z Forum - View Single Post - Interest Thread: AAM Competition 2.5" H-Pipe + Res Mid-pipe to shorties or stock rear

Now yes, I do realize this will be extremely loud, bordering on what most people will consider rice/fart can, but I'm curious as to how much of the VQ's raw sound I can extract before I go deaf or get a ticket.

I currently have the short tails, which are a wonderful set of pipes. I think my hearing has degraded recently, but it's a small price to pay for the raw VQ sound!

I'd gladly look for a system that essentially eliminates the factory Y pipe and midpipe for a more free flowing, straighter H pipe configuration. I will soon be installing an OBX Y pipe and some test pipes until this system is developed. Let me get one thing straight though, you are retaining the Y pipe and redesigning the midpipe? Or are you taking out the Y pipe and midpipe, then redesigning them as a single (or two piece) H pipe?

Maybe some 12-18 inch resonators on the midpipe (after the H joint, before the muffler) would eliminate most of the low-RPM drone. Or perhaps create a Helmholtz resonator.
