Why not get someone else drive your car and then follow it in their car. That way you can hear the real sound without the risk of losses due to recording quality ?? MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!

So, i finally recorded this using the gopro, trouble is the ebay mic I bought was rubbish, so I had to just use the camera on its own,

the filesize is about 1. 7gb fo a very short bit of film, and it takes too long to upload, i left it for 16hrs but my broadband is too slow! Discovery 4 HSE

I hope to get this exhaust

I have a similar system; catback, stainless steel, X pipe, retain back box, twin valve. I bought mine May 2022 based on watching that video! Profusion Exhausts Ltd. near Heathrow, Berkshire, did the making and fitting over 2 days.for just under £2300. Apart from maintenance, the best money I've spent on the vehicle.

Oh, valves open and closed sounds just like it does in that video. Real life hearing is believing! Bloody Awesome.

Thanks for letting me know I'll contact them

I am getting exhaust from Guerrilla fitting 2 x 5" racing cats to it. Also engine just about ready to go in oversized pulley on cramck shaft and supercharger. Programmable remap too. Chains, tensioner and water pump replaced. All injectors replaced only 2 would come out with puller. Got 2 set of wheels summer 22" Overfinch with Pirelli Verde tyres and 20" with Nokian AT tyres.
