smudge 1020 Report post Posted July 1, 2014 My new setup on the 86 is a big improvement, but just needs to be a tad louder in my opinion. It's made up of: Borla UEL headers Berk overpipe Berk HFC Invidia Q300 catback The Invidia's midpipe has this larger section in it Am I right in assuming that this would act as a silencer, and that with a straight pipe it would be a bit louder?

Special K 442 Report post Posted July 2, 2014 Looks like a silencer... but could be their version of a resonator... My H&S straight pipe was certainly louder than the silenced version currently fitted.. very similar looking to the above.. Spec K Share this post Link to post Share on other sites
Riceburner 284 Report post Posted July 2, 2014 That is a resonator,replaced with a straight through pipe would increase the sound considerably.The system is designed to run with this,so changing for a straight through May sound terrible.Its a case of try it and see what happens.

Keethos 842 Report post Posted July 2, 2014 This will not be applicable to you directly as each system is different, but as a rough idea, my Cobra non-resonated system with the 2nd CAT delete was reading about 108dBs, with a resonated pipe instead, I dropped down to about 89dBs. 108dBs IS LOUD! Not to say that this will happen to your system, I'm sure this isn't the case with Millteks but it will make it louder, the question is how loud and you won't know that till you try it (and probably after it's been ran/carboned up as it will get a lil quieter once it's carboned up). After more volume are we? Share this post Link to post Share on other sites

After more volume are we? Let's put it this way. My old 350z was recorded at 110dBs TRACKSIDE at Castle Combe last year. That's a good 30ft away from the actual car Here's a video to give you an idea, although in real life it's obviously a lot louder [TUBE] [/TUBE] I like volume, as long as it's not raspy or drones in the car on motorway journeys. From my experience, if you have quality parts like I did on the 350z and on the GT86 now, volume isn't an issue inside the car Booked in to get a custom straight mid pipe made up on Saturday, will post videos after and see what we think Share this post Link to post Share on other sites
Lauren 2259 Report post Posted July 2, 2014 110db is ridiculously loud and way too loud for the track and for the road. That would just drive you (and everyone else) nuts driving around with an exhaust like that. Share this post Link to post Share on other sites

I'm only a bit passionate about this subject as I used to run the pitlane for bookatrack and when we had cars that were as loud as your's going past me at full throttle made me want to kill the driver with a slow painful death as it was just incredibly painful and totally unnecessary. Still, glad the GT won't be as loud! Share this post Link to post Share on other sites
smudge 1020 Report post Posted July 2, 2014 I still don't understand the need for noise limits at tracks Yes, I understand the locals don't like it. But surely if you don't like it, don't like near a racetrack?! Share this post Link to post Share on other sites

But surely if you don't like it, don't like near a racetrack?! Someone has to live there, and as much as I like cars I wouldn't want to live next to a track with no noise limits... If you upset the locals it can cause a track to be shut down. It's not only the locals but it can affect wildlife as well I guess. Tracks tend to be near rural land after all.

smudge 1020 Report post Posted July 4, 2014 Wanted to get a before and after of the exhaust. So these videos are with the resonated mid pipe that comes standard with the Invidia [TUBE] [/TUBE] [TUBE] [/TUBE] Tomorrow will be the same videos but with a straight (unresonated) mid pipe Watch this space!
