When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “braappp!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cu\u003eProduct Details:\u003c\/u\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch2\u003eDesigned and tested on a real car in the real world\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eT304 stainless steel, TIG welded back-purged construction\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eReplaces restrictive factory catalytic converter\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eInstall hardware included\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eGreat power upgrade with uncompromising performance\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eIncredible sporty exhaust sound, subtle when cruising\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eNo drone with factory exhaust\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eStunning polished finish for great looks\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch2\u003e2018+ Audi S4 3.0T (EA839)\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003e2018+ Audi S5 3.0T (EA839)\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTo remove the CEL that will occur, proper tuning software must be used.
