I'd mentioned in a couple of posts that my car came with a brand new set of short tails, boxed up and I can now say I have had them fitted.
First of all the job of getting the OEM rear box off and the new pipes on took 1hr at a local garage and cost me the equivalent in labour. The pipes look good when fitted and the end sections fit quite nicely into the bumper. I think the trims are slightly smaller than OEM and are actually round where the OEMs are slightly oval.
I'll cut straight to the chase and explain that these pipes are loud. I'm still getting used to them and trying to judge how loud they are; I'll explain a little bit more. On cold start up the throttle blips up and settles at 1500rpm. If you live in a quiet cul-de-sac this is going to annoy your neighbours. However once it settles (to 600rpm (you can actually do this by giving the throttle a small blip) the exhaust gives off a nice steady burble. On part throttle the exhaust is relatively docile. It's still noisier than an aftermarket exhaust with a rear back box but this exhaust has got me thinking as to whether I'd be a bit miffed if I'd have spent £1200 on a Milltek non-resonated to find that it's still quite tame. I'm only speculating as I'd have to experience one first hand to have a real opinion. On full throttle it's a screamer though and you really get a feel for that V6. Downshifts are now a joy and theres gurgles and pops on the overrun.
The noise frominside the cabin is a little intrusive at times. For example, on full throttle there's a frequency though about 4000rpm that vibrates the boot lid momentarily and that's quite uncomfortable. As we know sound deadining isn't great on the 370 so you hear quite abit from inside but I ran the car up to motorway speeds this week and it's not intrusive at all, no drone like you'd get from a true straight through exhaust. In fact, the exhaust is loudest through 1st, 2nd and 3rd gears as you migth expect. Run it higher than this and I'd say it's quite acceptable.
The jury is still out on whether it's 'too loud' as I only have the standard set up to compare to and many many videos I've watched on the net. I have a feeling it's on par with a Jag F-type V6 S with the valves open, if you've ever heard one of those.
I'll post the video in a min when I've worked out how and I'll try to get more posted in the near future when I've had a proper play with my GoPro. In the mean time let me know if you have any questions. This exhaust is staying for now but will certainly be for sale when I come to exchange my 370Z for something else in 2016.
