No sound clips sorry, but my friend has SLPs dumped on his car. Its got a HCI, Long tubes, Off road X and SLP resonators, and the car is LOUD. It might be too loud for the street and to me doesnt sound great down low, but gets real raspy through the mid range, and screams up top. I would love to hear some with tails on my car, but unless I get some to borrow, I can help with a sound clip, sorry!
Again, no clips. I have a SLP LM1 kit on my LX. It's a H/C/I car with FRPP shorty headers and Bassani catted X-pipe. It has a deep rumble at idle, sounds very aggressive but not overly loud under normal accelleration, but young children and animals run screaming at full throttle. Literally. I love it.
