Richjb 0 Report post Posted June 25, 2022 Hi, I'm looking for a quiet performance exhaust to go with a TD EL manifold, in particular no drone on the motorway. I currently have a TD super-resonated. Especially interested to know if anyone has paired the Hayward & Scott Cat Back System with larger centre silencer with a catless manifold: https://www.haywardandscott.com/.../toyota-gt86-cat-back... The Ark Performance Grip seems like a good contender if anyone can share their experience. Thanks! Share this post Link to post Share on other sites
willclarke 50 Report post Posted June 25, 2022 Myself and @3782mc have the one up from that, the Hayward and Scott Helmholtz resonator cat back and it's brilliant, no drone (by design) and overall quieter than most other cat backs with decat manifold. Borderline too quiet actually with stock front pipe so I went for a HFC and was a good compromise. https://www.haywardandscott.com/toyota-gt86/toyota-gt86-with-helmholtz-chambered-rear-silencers-and-silenced-centre-pipe.html Sent from my Pixel 6 Pro using Tapatalk Share this post Link to post Share on other sites
BRZ-123 174 Report post Posted June 26, 2022 The invidia Q300 is also excellent with decat manifold. It's a bit too quiet with OE manifold. Sent from my SM-G781B using Tapatalk Share this post Link to post Share on other sites
