Hondata exhaust drop down menu: Straight pipe
Posted: Fri May 02, 2025 9:31 pm
Hello, I recently got the Hondata flashpro for my 2021 civic type r. I have a full straight piped oem exhaust and was wondering what exhaust option I should choose in the mod menu under Hondata. Since it’s not oem the back pressure would be different, but the exhaust diameter is the same as oem. So should I choose an aftermarket exhaust in the menu or keep it as stock? If so which exhaust should I choose? Thanks!
