991.1 C2S - Exhaust upgrade with Topgear

[FrancisA]

Hi All
I am looking to upgrade the exhaust on my 991.1 C2S.

An indy service centre has proposed the side box deletion using Topgear exhausts.

I wanted anyone with experience of the same to share their experience in terms of noise and any noticeable performance increase. In addition any observations on the quality of Topgear’s exhaust products. Finally any advice on an alternative exhaust upgrade.

Thanks
