Quieter performance exhausts (or muffler add-on options)

[f00stx]

So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area.

It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so....

... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z?

And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

Nope.

Grab a varex and turn it down as you get close to home, win win?
