    Lid makes a huge difference with horsepower gains and also looks way better under the hood. Very easy to install and we'll worth the price

    SLP Loudmouth Exhaust Camaro V6 2010-14 Axle-Back System w/4 inch Tips

    I really like the exhaust; but I was incredibly hesitant to buy for weeks because I just didnt get a serving-justice sound (confidence) in the exhaust. I tried youtube, but there are no videos for this exhaust on a 2013 LT model. A possible clip of its sound would do awesome...! Thanks

    Current Mods:
    Exchanged stock exhaust with SLP Loudmouth Exhaust for v6 2010-2014 Axle-back system.

    After having to drill out the passenger side flange, because it was way to small for the bolts and buying nuts for those bolts because they weren't included, the install went very well and the out come is a very very happy customer, love the sound especially combined with SLP Loudmouths and BBK shorty header. I'd recommend theses X-pipes to anyone want a very loud and VERY aggressive sound...now just to install the BBK Throttle Body that i bought along with theses X-pipes good job SLP and LMPerformance for getting them to me before Christmas...

    Current Mods:
    BBK shorty headers...SLP LOUDMOUTH exhaust and BBK Twin Throttle Body
