Hello fellow Kieran and GSF owner 😉 I will try and give you as much info as possible to hopefully help!

If you want noise, the mid pipe is where to get your primary improvement at a lesser cost then lets say headers. Back boxes only make minor changes (from sound clips heard online). I went for both but back boxes are valved.

So I have GTHaus midpipe (secondary cats removed) and backboxes installed (yes I realise they are from US), I looked into pretty much every option before purchasing. What I found comments to be about the other 'brands' were that they literally got no noise improvement or in some cases felt it made it sound worse and you've just spunked a loada money on it. I came to the conclusion that I would need to look at Jap/ US options (Novel and GTHaus were on my list).

I did successfully barter with GTHaus on price and shipping costs and found them quite open to negotiation. However, the problem lies in that your budget is not suitable for these options I am afraid.

As suggested above, it would potentially serve you well to approach someone locally and investigate options. Any other questions please don't hesitate to ask on here or pm me 🙂

Hi there. Kieran your option sounds very good. Do you have any posts at all with the sound recorded? When I have listened to various GSF exhaust alternatives, they all sound fairly similar once the initial start up excitement is over. I Am also wondering about some exhaust enhancement but also very much aware that when I had my really quite loud Porsche Panamera GTS, I tended to turn the exhaust “off” most of the time as it was just too loud for an old git like me!
