Jcg1 Posted 22May, 2022 Report Share Posted 22May, 2022 Hi guys, anyone use tubi side mufflers on their 997? What does it sound like any drone? what mufflers have you used on the sides. cross pipe already installed across the back and not loud and angry enough. cheers Quote Link to comment Share on other sites More sharing options...
sjm Posted 22May, 2022 Report Share Posted 22May, 2022 Standard 997.1 C2S boxes with 1 3/4 inch bridging inlet to outlet pipes. I think it’s pretty loud along with quite a few other people. It’s a traditional gundo/ fister mod. There’s another mod that cuts into the muffler itself from inlet pipe to bypass a couple of baffles, but that was mild in my opinion.
