    SLP or SUPER LOUD PERFORMANCE

    i bought the slp LM1's. I had flowmaster 40's on my mustang bullitt and they only made noise at about 1950-2200 RPM, these are loud from idle to 6 grand! i lovve them and would recommend them to anybody who owns a v8 mustang. of course though, keep your foot off the gas going by cops!

    Sound that turns heads

    I have a budget, so I decided to buy these and install them for under $300. When I did - Heaven shed a tear. Its loud, powerful sound irrupted and now my 03 GT stands out. I love being at the Gas station, firing it up, and just smiling as innocent bystanders watch me drive away.

    ABSOLUTLY AMAZING

    These are the best mufflers you can put on your car for sound and power!!! however I must warn manuel drivers you will get much worse gas milage not because they affect the car but beccause you will crave the sound when you hit 6grand!!! Best! Best BEST EXHAUST mod you can do!!!

    AMAZING!!!

    This changed my car from a normal road car to an all out drag car! It's much louder than just a normal cat-back and when you get n the high revs it really sounds great! With in an hour of putting these on I got a tone of looks and one guy even pulled up next to me and said "dosnt sound like a cheap one!" and gave me a thumbs up! These are a must for an mustang owner!!!

    Sounds awesome!

    I have these pairs of slp loudmouth resonator mufflers with an o/r h pipe and it sounds just perfect. It has an aggressive tone with a rich deep throaty sound and just a bit raspy. This is the sound I always wanted and I got it with the slp loudmouth mufflers. Was very happy with the price and installation was fairly easy.
