Twallis Posted July 2, 2015 Share Posted July 2, 2015 (edited) 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.

brillomaster Posted July 2, 2015 Share Posted July 2, 2015 The exhaust will get a little quieter as it soots up inside, but bet it sounds lovely! keep it on for a few months before making a decision on whether to keep it on or not. But have to say, after having a sports exhaust on a zed, going back to a standard exhaust just sounds so tame in comparison. missing the pops and crackles, will have to get cs to put a sports exhaust on my beemer when its next in for a service. 1 Quote Link to comment Share on other sites More sharing options...
Twallis Posted July 2, 2015 Author Share Posted July 2, 2015 It's quite a raw sound at the moment. I like the noise, I think I'm just a little conscious about whether it's 'boy racer' instead of purposeful sports car. Quote Link to comment Share on other sites More sharing options...
brillomaster Posted July 2, 2015 Share Posted July 2, 2015 Boy racer would be putting a 4" fart cannon on a 1 litre corsa... having a loud exhaust on a 3.7 litre V6 is what is should have sounded like from the factory, rather than the shopping trolley exhaust they put on as standard. Trust me, let it settle down a bit and then in a few months time, you'll hear a standard exhaust and just think it sounds crap in comparison Quote Link to comment Share on other sites More sharing options...

Yours will sound a treat with a pipe Quote Link to comment Share on other sites More sharing options...
Twallis Posted July 2, 2015 Author Share Posted July 2, 2015 I like your thinking Brillomaster. I shouldn't have to remind myself that it's not some chavved up 1.4 POS. Quote Link to comment Share on other sites More sharing options...
Bundus Posted July 2, 2015 Share Posted July 2, 2015 I have the Cybox short tails on mine too. I love them. You can actually drive slower and still enjoy the car as opposed to having to boot it just to enjoy some sound. I sound deadened my boot with 12mm thick carpet underlay and it made a big difference. Its not really any quieter inside but there are zero rattles or drones at any rev range now since all the plastic trim is padded from underneath. Id never go back to standard now, not after enjoying the roar on downshifts with SynchroRev on. Quote Link to comment Share on other sites More sharing options...
Twallis Posted July 2, 2015 Author Share Posted July 2, 2015 Bundus. Did you just put the underlay between the boot carpet and resess for the Bose sub? I agree with you on being able to drive slower and enjoy the noise. I found myself booting it when it was standard just to get some sound. The downshift noise is brilliant. Probably my favourite part of the sound after the overrun burbles. Quote Link to comment Share on other sites More sharing options...

I agree with you on being able to drive slower and enjoy the noise. I found myself booting it when it was standard just to get some sound. The downshift noise is brilliant. Probably my favourite part of the sound after the overrun burbles. I went full on and removed all the boot trim as well as the Bose Sub and anything else that would come out. I then used contact adhesive to glue the underlay down to the boot floor, boot walls and wheel arches etc. After that I just refitted all the plastic trim. It was tough getting the trim back in as it was all very tight but that's why I no longer have any rattles or drones. Well worth it mate.

Twallis Posted July 2, 2015 Author Share Posted July 2, 2015 (edited) Here's a short clip from some GoPro footage I took. It's stuck onto the spoiler so apologies for the wind noise. I'll experiment more over the next month or so and upload some more footage. Let me know what you think. http://s141.photobuc...html?sort=3&o=0 Edited July 2, 2015 by Twallis Quote Link to comment Share on other sites More sharing options...
brillomaster Posted July 2, 2015 Share Posted July 2, 2015 aww man i miss a V6 easily the best engine sound one can actually afford, bettered only by a V10 in my opinion! Quote Link to comment Share on other sites More sharing options...
