I have been researching pipes for months and have read thousands of threads, spoke to tons of people, and have seen dozens of bikes with Rinehart TD's. I love the sound of Rineharts because they have more of the true deep Harley rumble. In fact out of all the pipes out there, I had my choices narrowed to V&H or Rineharts.
Most people with Rinehart's complain how loud they are at cruising speeds, which is a turn off for me. Also, I think the biggest complaints leading me away from Rineharts is fitment and QC issues; such as, headers cracking, fitment issue around the brake lever and timing cover and of course the color changing end caps.
I have read a plethora of threads about people complaining about their Rineharts due to several factors, but they all love the sound.
When my turns comes around to replace the pipes on my SERK, I am planning V&H true duals with oval slip-ons. Everything I have read, and everyone I have spoke to absolutley loves them. They states the Vance and Hines are top quality pipes, i.e. fit, finish, perfomance and sound.
If I put a set of pipes on the bike, I only want to do it once and not have to swap out an exhaust system or part due to multiple warranty / quality control issues (Rinehart's)...
Looks like I'm going V&H for mine. Just my input, your mileage may vary

Do your homework....
