I just want to say thankyou to everyone who gave me information and suggested Roadhouse 65 Specials for my 05' SS750. I put them on this weekend with some minor setbacks such as getting off the stock pipes and them sending the right kit but wrong directions (Spirit 1100 directions). I removed the baffles before starting the bike up. When I started the bike it just about blew me out of the garage! The sound is amazing and its louder than most harley's I've heard. I bought the scratch and dent special and the pipes are flawless so for a total of $230 dollars including shipping this was definately the right move. I have a buddy with 750 spirit and he has Vance and Hines with a jet kit that cost him about 600 including installation. This kit sounds just as mean if not meaner for way less. I recommend these to everyone I couldn't be happier with my choice. So once again thanks for eveyone's input on this it's just plain awesome. I'll post some pics soon and video's so you can hear what it sounds like. Might cut baffles in half since I will probably sound like an a-hole or get a ticket.
