adam_350z Posted March 28, 2015 Share Posted March 28, 2015 Hi all, Bought my 350z with a japspeed k1 on it. However im sick of the drone on the motorway and when cruising - even with baffles in place. In terms of looks i like the cobra resonated system most, however im worried its still going to be quite droney? Which pushes me to the scorpion but im not a great fan of the tips. I dont want a quiet exhaust under full throttle i just want rid of the drone.😠Anybody with the cobra resonated able to put my mind at ease?

KyleR Posted March 28, 2015 Share Posted March 28, 2015 Some say their Cobra drones, others say it doesn't. In my opinion, the latter are in denial Pretty much all aftermarket exhausts will drone a little, it's personal preference how much you can deal with. The Milltek is pretty quiet until you mash the accelerator, but it's also quite pricey. Quote Link to comment Share on other sites More sharing options...
GMballistic Posted March 28, 2015 Share Posted March 28, 2015 I don't feel that my Invidia Gemini really drones but it is a bit more pricey than the Cobra/Scorpion brands. Quote Link to comment Share on other sites More sharing options...
SHEZZA Posted March 28, 2015 Share Posted March 28, 2015 +1 for invidia Gemini and depending on what your y pipe is or it's condition is if that also needs replacing the price of the invidia is not much more than a complete cobra cat back system. If you y pipe is good though and your on a budget cobras a good option also, and I seen you can get the miltek system from y pipe back from Clark Motorsport Quote Link to comment Share on other sites More sharing options...
alexwitham Posted March 28, 2015 Share Posted March 28, 2015 I have a Scorpion and it doesn't drone one bit. It's also not that raspy, no popping or farting either, It's loud enough for you to realise your running an aftermarket exhaust but quiet enough for that stealth mode if the revs are kept below 3k.

adam_350z Posted March 28, 2015 Author Share Posted March 28, 2015 Invidia gemini looks lovely, but i aint paying a grand for an exhaust. Especially when you only see the rear of it 😠Scorpion is a possibility then. Im guessing the resonated cobra will still be a lot quieter than the japspeed?

alexwitham Posted March 28, 2015 Share Posted March 28, 2015 One thing to note with the Scorpion - I had issues with fitment, it was fouling the rear axle/chassis so required some heat on a bracket and a bit of bullying to bend to a better fit. Quality wise, it's cheaper for a reason I guess. But having said that, it does make a good noise Quote Link to comment Share on other sites More sharing options...
daveallen1999 Posted March 28, 2015 Share Posted March 28, 2015 I have a resonated cobra system myself. It does have a small amount of drone at about 2500rpm. But I have got used to it, especially when I take it above 4000rpm and it roars into life! Quote Link to comment Share on other sites More sharing options...
adam_350z Posted March 28, 2015 Author Share Posted March 28, 2015 The problem with the interwebs... how much is a small amount of drone Quote Link to comment Share on other sites More sharing options...

GMballistic Posted March 28, 2015 Share Posted March 28, 2015 The problem with the interwebs... how much is a small amount of drone The real problem is everyone hears things differently. Personally I think you really need to hear these things in person though so you may be best off going to a local meet. At least that way you won't spend money on an exhaust system you don't like because you find it drones. Quote Link to comment Share on other sites More sharing options...
adam_350z Posted March 28, 2015 Author Share Posted March 28, 2015 Probably right! Think its just because the k1 is at the extreme end of the scale, if i had a standard just now id go straight for the cobra resonated and not think twice 😕 Quote Link to comment Share on other sites More sharing options...
Chris Wiltshire Posted March 31, 2015 Share Posted March 31, 2015 I've got a cobra resonated going up for sale. It does drone a little at a certain rpm but once going on the motorway it's quiet until you put your foot down. Has a great v6 sound. If I remember it droned a little if say you drive in 5th/6th at slowish speed.. Just fitted a Motordyne and this doest drone at all now it's bedded in.

brillomaster Posted March 31, 2015 Share Posted March 31, 2015 i have a cobra resonated, the only time it drones is if you go full throttle in 5th or 6th at 2,000 rpm. It also started worse, but got quieter as it was run in, so much so that I don't notice it anymore. but cruising on the motorway its fine, as you're above 2,000 rpm. and in addition it sounds great over 3,000rpm, and pops and crackles when its warm.

veilside z Posted March 31, 2015 Share Posted March 31, 2015 My lads in the process of exchanging stock , for R35 gtr exhaust, in removing the centre section and fitting decats. Probably a lot if adjustments needed, but looking forward to the sound with interest. Quote Link to comment Share on other sites More sharing options...
Bodyboarder81 Posted April 7, 2015 Share Posted April 7, 2015 I would say invidia ..... Without HFCs or decats for a nice sound , no drone and brilliant build quality . Scorpion for the cheaper option , but expect fitment issues .... Does sound nice and absolutely no drone ( unless you fit HFCs / decats ) 1 Quote Link to comment Share on other sites More sharing options...
galgazza Posted April 7, 2015 Share Posted April 7, 2015 Having the Invidia fitted next week and will let you know how different it is from the standard. Must say I cant wait. Quote Link to comment Share on other sites More sharing options...
mikejbry Posted April 8, 2015 Share Posted April 8, 2015 Cobra resonated fitted to a HR here, it drones between 2000-2500 rpm, it gets on my tits a bit, but when cruising I learn to drive around it, either up or down a gear. If you are hung over its not a great noise haha. I can't say that everyone who says it doesn't drone is lieing, but I can definitely hear it. On the plus side, it does sound pretty damn good Quote Link to comment Share on other sites More sharing options...

Luke0549 Posted April 24, 2015 Share Posted April 24, 2015 how about a japspeed k2? i had one and thought it was great. Looks standard, quiet on idle/normal driving, but give it some beans and it makes a lovely noise thats not too in your face. a lot of people slate them for their build quality. But i didnt have a problem with either of my k1s or my k2. Quote Link to comment Share on other sites More sharing options...
