need your opinion

[OD]

have a MAC pro chamber right now with magnaflows, i was thinking of swapping out them for flowmaster 40 series. i like the deeper sound of the flowmasters... but i dont know...

any thoughts on this? will i gain/lose power?

You probably wont gain or lose any power. Why dont you trade those magnaflows with some magnapacks? IM me at coman87 for sound clips.
