Product Description
The Rev9 FlowMAX catback (Part # CB-228 )is a direct bolt-on exhaust upgrade for the 2018-2022 Honda Accord 10th generation in both 1.5T and 2.0T variants. The system runs 2.75" (70mm) mandrel-bent T304 stainless steel piping with TIG welded joints and CNC machined flanges throughout. It exits through the factory rear bumper garnishes using the factory mounting points, so it keeps a clean, stock-looking fitment from the outside while giving the Accord a noticeably different exhaust note. All gaskets and hardware are included for installation.
The quad muffler tips are double-walled stainless at 4", and the muffler canister is also stainless. The larger 2.75" piping over the factory diameter improves exhaust flow and gives the 1.5T and 2.0T engines a deeper, more aggressive tone under acceleration. At highway cruise the sound is refined enough that it is not intrusive for daily driving, which is a common concern with catback exhausts on a sedan like the Accord.
If you are also looking at other upgrades for your 10th gen Accord, we carry Accord coilovers and a full range of suspension parts for the CV1 and CV2 chassis.
