Best way to quiet your SLP Cat-Back
Originally I had bought the SLP LM1 cat-back system for my 2003 Mustang GT. When I first installed it I thought wow, this is pretty loud. A few months later, I was too used to it and found it to be quiet. So I installed a full length catless H pipe. It was amazingly loud, too loud, and had a machine gun sound on the highway. So rather then get rid of the SLP cat-back, I bought the Powerflo\'s. It is very hard to find ANY reviews on this product, as you can tell by mine being the first and only one on here so far. They sound deeper, and are MUCH quieter then the LM1\'s. They have no machine gun sound, and are so much more quiet then the LM1\'s. I would say it is now just a little louder then what I used to have when it was JUST the lm1 cat-back. I would highly recommend this product to anyone looking to quiet down their SLP system.
As always, thanks American Muscle, free shipping and I received them in two days.
