I've tried to search the forums for some useful information on this issue, but I've been unsuccessful. So I'm just gonna ask, what mid-pipe systems sound the best with the SLP Loudmouths? Should I go Off-Road, On-Road, H, or X? I think my LM's sound great but I need more.
So, please help me out and leave a video tag too if you have one.
