Yea Ive had both systems before and the loudmouth is just to overwhelming. My loudmouth catback only was louder than my lts, off road ypipe, and magnaflow combo. Im positive its just a sound difference.

The reason I switched is due to how loud it was. I could never hold a conversation with the SLP. With the magnaflow, I can finally hear people.
My SLP loudmouth made 8rwhp over my Magnaflow cat back. I cant tell any power diference myself.
Ex. I have a 71 Nova that had a 454 in it. It felt fast, but lost its *** on the top end. I could out accelerate an F-body up to about 40-50, but lost ground after that.

I got the timeslips to prove the change makes a difference! I had my lm2 exhaust installed last year. I didnt like the loud sound from the lm2 with my h/c package. I ordered a magnaflow bullet, but decided to get a before and after timeslip test. With the lm2 I ran a best of 12.35. With the only change being the magnaflow bullet install I went back to the track and my first pass was a 12.05 and after cooling it ran 12.03! The magnaflow was much quieter and I was surprised with the faster et!
