Crudeoink Posted August 31, 2023 Report Share Posted August 31, 2023 Hi all! I'd like a bit more induction noise on my 987.2S and have recently taken the battle out of the side grille, which added marginally more noise. I've since ordered a BMC filter to add a bit more noise, has anyone else been down this route to get more noise? Did it work out ? Anything I can do to add more noise if this doesn't cut it? I dont really want any more exhaust noise as the car already has a Carnewal backbox and tests at 98dBa Quote Link to comment Share on other sites More sharing options...
MickH Posted August 31, 2023 Report Share Posted August 31, 2023 What you want is the MRN induction kit. I have one and its very loud Quote Link to comment Share on other sites More sharing options...
Crudeoink Posted September 1, 2023 Author Report Share Posted September 1, 2023 I'll take a look at this thanks! I'll have to report back on the induction noise once the BMC Filter from D911 arrives, not expecting much but hopefully a bit more noise Quote Link to comment Share on other sites More sharing options...
Guest Posted September 1, 2023 Report Share Posted September 1, 2023 I took ALL the engine covers off a few months ago to clean the engine and took her for a spin with them off and you'd be amazed at how much these covers protect from sound and especially heat. Induction noise was incredible with just a desnork and dry performance filter but you'd be hard pressed to drive more than a day or two with them removed..... the engine heat is amazing. Intrigued by the induction kit and would consider one if i was contemplating selling her. Si. Quote Link to comment Share on other sites More sharing options...
mr.tourette23 Posted September 2, 2023 Report Share Posted September 2, 2023 What about one of those clear engine covers? Gets rid of the insulation, keeps out the heat but lets more noise into the cabin.. also looks pretty cool if you keep the engine clean Quote Link to comment Share on other sites More sharing options...

Lonewolfgjp Posted September 2, 2023 Report Share Posted September 2, 2023 I managed to get a great sound out of my 987.2s by removing the side baffle and fitting the BMC replacement filter. My car also had the factory PSE and I also had the car remapped which improved the cars sound and made the power delivery smoother and responsive 👍 Quote Link to comment Share on other sites More sharing options...

The BMC and a few other bits should be arriving today. I'll try and get around to fitting it and reporting back on some increased induction noise! However the arrival of an 8 week old puppy is currently putting the brakes on most activities at the moment 😅 Edited September 4, 2023 by Crudeoink Quote Link to comment Share on other sites More sharing options...
Pothole Posted Monday at 08:49 PM Report Share Posted Monday at 08:49 PM How did you get on with the BMC and the baffles removed? I tried the BMC on my 987.2 S Cayman and no other changes, and honestly I didn't think it made any difference at all to the noise, which is the only reason why I bought it. So, I took it straight back out. I'd really like to improve the induction noise as I'm not a fan of loud exhausts and for me it's the induction howl that marks out a flat six. With a loud exhaust, these cars just sound generic., Quote Link to comment Share on other sites More sharing options...

If you do find a way to increase the induction noise I'd be interested as much as exhaust noise is cool, induction noise is cooler! Quote Link to comment Share on other sites More sharing options...

Have you considered blocking off the helmholz chamber in the airbox? Popular trick on 911s. Prob because it's dead easy to get at on 911s of a certain vintage - 996s or 7s - can't recall which.

Mattman42 Posted 7 hours ago Report Share Posted 7 hours ago Seen some posts suggesting moving the connector clamp on the exhaust to create a gap and more exhaust noise - no idea if it actually works. Have also done the desnork and find it more noticeable when the roof is up Quote Link to comment Share on other sites More sharing options...
