Bigger injectors effecting exhaust tone?

[Smoke Panther]

Is this possible? I bought some LS1 (26.3#) injectors to make the ARH-NA cam feel more at home, and after i got them in, the exhaust tone was noticibly deeper. Is this normal for going to bigger injectors, or did I botch the install?

i hope you have a tuner, cause odds are you are running pretty rich. Your cars computer requires a tune when switching injectors.

If you hear a diff. its cause your car is running much to rich.

Gain access and make sure you update your tune to reflect the larger injectors. Otherwise you will eventually run into some problems with engine knock.
