Had the guy who did my engine put the long-tubes on. He said it was the worst set he's ever had to do. I was more than happy to pay him a couple hundred to do the job.
Seems to have a little more low end torque and the mid range has picked up and smoothed out noticeably. I'm not sure on the top end yet cause Regina Muffler and Brake hacked a mid pipe and welded it to the cat-back causing other weird problems with the system.
