Gramps Posted December 19, 2021 Report Share Posted December 19, 2021 Hi All. I've been trying to get a good audio sample of the Topgear manifolds/PSE set-up I have on my Gen 2 Boxster S exhaust. I bought a Sports action camera and tried that suckered on above the number plate looking down at the exhaust tips and took it for a drive but it seems too much noise for the camera to handle and didn't sound good. It was marginally better with the car static but still doesn't do it credit. Tried it suckered onto the rear of by my wind deflector, and also tried my Garmin dashcam alongside it but again neither sounded great. It doesn't have to be video as well, just audio if there's a way to do it justice. Would trying different frame rates on the camera help it handle the audio better? Can anyone offer some practical advice on how to get a good recording because I think it sounds awesome and wanted to share it with you guys.

Menoporsche Posted December 19, 2021 Report Share Posted December 19, 2021 Thought there was an exhaust vids thread? Not sure if it gives pointers. 1 Quote Link to comment Share on other sites More sharing options...
DisplayName Posted December 19, 2021 Report Share Posted December 19, 2021 (edited) How is the sound recording not working? Does the sound playback sound like it's breaking up? Or is the sound of the exhuast being drowned out by the wind noise? I believe if it's breaking up: a better quality mic? What exact device are you using? If it's wind noise then a dead cat / windscreen on the microphone solution Edited December 19, 2021 by DisplayName Quote Link to comment Share on other sites More sharing options...
Barclayboy Posted December 20, 2021 Report Share Posted December 20, 2021 I’m by no means an expert However having done many road trips with friends who are they all use an external microphone Have a Google, YouTube search for the best microphone for your type of camera 1 Quote Link to comment Share on other sites More sharing options...

Yes the playback sounds like it is breaking up, could obviously be the quality of the mike. The camera is an Akaso EK7000, not the best I know but pricewise I thought I'd give it a try. I did have a GoPro Hero but that went for posh one when it was on my track bike that got trashed 😭. As mentioned the sound is better when the car is static, but I think the road and wind noise once moving is too much. Quote Link to comment Share on other sites More sharing options...
Ninesomething Posted December 20, 2021 Report Share Posted December 20, 2021 These things normally have great compressors built in so it's almost certainly wind noise on the mic. You could try simply tying some fabric over it see if it works. Over the mic not the lens..... Quote Link to comment Share on other sites More sharing options...

Unfortunately it's never obvious if a generic USB mic will work with camera XYZ, so some Googling of the exact model number and mic suggestions may help find something on Amazon/Ebay. As JonSta mentioned you'll struggle to get a good sound out of the inbuilt one but a bit of fabric may help a little bit. Quote Link to comment Share on other sites More sharing options...

Yeh, been having a google for an external mic for my model but seems not an option on my model. Even those that do have the option I don't think would work unless they were able to plug in through the protective glass case that is needed to mount the camera? Saw YT vid where the guy used an external mic for his iphone and married it with the video footage. Still looking and will experiment more.

Gramps Posted December 30, 2021 Author Report Share Posted December 30, 2021 My boy kindly offered to have a drive of the Porsche yesterday. So took a couple of vids.

Ninesomething Posted December 30, 2021 Report Share Posted December 30, 2021 I found this - they say this is the place where a lot of the generic stuff comes from. Sent them a message but no reply. Could be closed for holidays I suppose. https://www.liangfei.com.tw/product_detail.php?uID=1&cID=165&Key=312 Quote Link to comment Share on other sites More sharing options...

When I done mine I teased each one out gently one at a time. Gave them a squirt of WD40 a few times over the course of a few days then worked on one bolt at a time. Slacken just a bit then tighten, slacken a bit more then tighten less etc giving it more WD40 as it went till the bolt was out,. Then I gave it some copper grease and put it back in. Then done the same with the rest. Didn't try tackling the job till I knew all bolts would come out ok. Luckily enough they all came out ok. Replaced them with stainless steel bolts when done. 1 Quote Link to comment Share on other sites More sharing options...

Replace all bolts with stainless steel studs and copper/ brass nuts then no issues if you ever have to remove manifolds again Quote Link to comment Share on other sites More sharing options...
