Just wondering if anyone ended up trying one of these systems (Evolution Full or Sports Cup)? Other than cost, the issue I see is the big torque drop in lower RPM ranges (see dyno charts on website) and fact that it would likely void warranty.

I have one on my Duc and love it. No experience on cars though

I've been considering getting the Sports Cup version. I am in an emissions region and don't know if the 100 cell cats would pass with the full system.

Do the 100 cell cats scrub less than the standard cats?

Jon70

I would assume significantly less.

I've owned many akro pipes for my various bikes. Have a full titanium evolution system on my gsxr right now. Fantastic pipes, extremely well made (the welding work is exquisite), and have real performance. If they produce a car pipe that's even in the same league as their bike pipes, i say go for it.

Oh yea they do. You'll never pass in CA.
