Honda Grom 2023, put around 800-900 miles on it being stock, I didn't mind it for what it was. Did a PSP / K&N air filter with the stage 1 Cam " STOCK " exhaust and I can say I tell a significant difference. I didn't see no more speed increases but I noticed 1 - 4 gears have way more torque it just feels what it should be from factory, 5th gear is better but can still tell it's a longgggg gear.
Overall I'm very happy with this upgrade I didn’t care much for speed I just wanted torque and it's what I got
