NathanT 1 Report post Posted March 20, 2021 Hi all, Looked on the forums here & ft86club, & couldn't find anything close to what I'm looking for. I've currently got a Cobra non-resonating catback & backbox, but find its MUCH too loud since I live in a relatively quiet neighborhood, so I'm aiming to replace it with something as close to OEM volume as possible & add an exhaust cutout for the choice between quiet & loud, but would like it to be stainless steel to it wont rust. What catbacks & backboxes have you run, & how close to stock volume were they? Share this post Link to post Share on other sites
willclarke 50 Report post Posted March 20, 2021 Are you running a catless header?The Hayward and Scott system with helmholtz that myself and @3782mc use are very quiet in comparison to a lot of aftermarket ones I've heard, even with catless header with oem front pipe, then slightly more noise when swapping out the front pipe for hfc / decat.

Thank you 1 willclarke reacted to this Share this post Link to post Share on other sites
Varelco 211 Report post Posted March 24, 2021 Invidia Q300 is the quiestest aftermarket exhaust for this car. Pretty much every aftermarket exhaust is made from 304 stainless, its a common grade stainless so its pretty cheap but it still rusts, just not as quickly. By exhaust cutout do you mean you want a valved exhaust? To switch between quiet and loud? Its possible but it will be expensive and nobody has done it.

There are loads on youtube that have done a custom exhaust cutout on a gt86. Some replace them after a year or so because the cheap valve gets stuck in one or the other position. If you want a cutout go for a proper system like an Xforce Varex, where it is all built in. Share this post Link to post Share on other sites
