SLP LM installed

I installed the SLP LM. So, far I like them. At start-up it's loud, louder than my last axlebacks: magnapacks. At idle it quiets down. It's fairly tame when you drive at normal speeds, but is loud when you step on it. Are SLP known to trumpet? I don't know if it's the nature but when I step on the gas peddle, I hear a blaring trumpeting noise. Or is that because of my mid pipe, prochamber w/hi-flow cats?

It's the slps. They are notorious for being very blatty like you are describing.
