Glanza_Mike Posted May 16, 2016 Share Posted May 16, 2016 Hi guys, tried TTC mode out for the second time Today and quite like it apart from the low down exhaust noise!! I can put up with the increase in noise low down in general but between 1.5k and 2k when i press the accelerator (doesn't have to be hard) the exhiast noise gets extremely loud!! It sounds like it's just resonating and it's really very loud. Is there any way to reduce or stop this? A single turbo Supra doesn't have this problem Would it be solvable by removing the exhuast butterfly? Or mapping maybe? Thanks Mike Link to comment Share on other sites More sharing options...
j_jza80 Posted May 16, 2016 Share Posted May 16, 2016 Singles do have that TTC unleashes the full exhaust flow onto both turbos, so it is a side effect of that. It's just that you have one of the loudest exhaust systems available for the Supra Link to comment Share on other sites More sharing options...

Glanza_Mike Posted May 17, 2016 Author Share Posted May 17, 2016 Haha, it woukd be fine if it sounded nice but loud but between 1.5 and 2k it just sounds super loud and like a fart can, after that i could put up with it. Link to comment Share on other sites More sharing options...
TheTurtleshead Posted May 17, 2016 Share Posted May 17, 2016 The boostlogic exhaust is your problem. Had one for literally a few days when I had a TT in TTC. Took it off and sold it almost straight away. A single would indeed be the same, but a different tone. Link to comment Share on other sites More sharing options...

Just keep it over 2k, there you go I've just saved you a few hundred, payment in beers is fine Link to comment Share on other sites More sharing options...
