I currently have the slp loud mouth axle backs installed on my car. I have run it with a bbk after cat x and resonators removed and gotten a lot of compliments on the sound. I am going to be running cat deletes shortly on the car (actually installed them and took them back off) and want a more tame not ear piercing sound. These were $379 new shipped, purchased on 5/16. The car now has 2600 miles on it and has seen light rain twice. I am willing to trade out these for gt500 mufflers so I can utilize the extra hp from deleting the cats. Let me know who is interested. Thanks!

I have some videos on facebook of the exhaust, but can not seem to figure out how to post them
someone who is not deleting their cats and has gt500's wants more sound... I know you're out there.. You know you wanna trade 
Post a vid. I'm about to add cat deletes and run it with my SLP Loudmouths. I wanna hear how obnoxious it's about to be. lol
I couldn't figure out to to post it, but trust me.... It's very loud. I like my cars loud, but I was embarrassed to drive it
either trade for gt500's or sell flat out 300 shipped obo
payment sent! Will pick them up Friday!
dropped off today. Thanks again!
