yeah i mean idk...i love the deep growly sound of off road H's but I also love the loud scream of off road x's!!! IDK WHAT I WANT LOL! oh and just to let you guys know i have the magnaflow magnapack catback which if u guys are unfamiliar with it basically doesnt have mufflers...there more like hollow chambers that u could literally roll a golf ball through like straight pipes and could be compared to SLP...so yeah its already really loud when u get on it but at idle and low rpm's its fairly quiet...
