would there be a noticable diff if I went from a white brothers e seiries pipe to an hmf pipe??

I dont think you would be able to notcie too much, maybe one would be a little louder than the other.

if you went with the full system you would tell a difference. but with just the slip-on sound would be better from the HMF but power might be slightly noticable over the E-series.
