Which 3" Downpipe and Testpipe to go with my HKS Hi-Power?

I have an 03 Evo VIII with the HKS Hi-Power exhaust and I am wondering which 3" downpipe and testpipe I should get that fits it. I don't really care about how loud it will be just that I want a testpipe that wont cause the check engine light to come on. As far as the downpipe goes I am leaning more towards the Helix or Perrin downpipe I just need to know which one will clear my RMR lower arm brace and which one wont rattle or rub against anything. So please help me out with which combo I should go with.



Thanks
Michael

I think the HKS HiPower necks down to 2.5" at the flange (to the stock cat location). You may have to get a shop to cut about 6" back and weld on a 3" pipe section with a 3" flange.
and Yes the DC-Sports 3" DP+testpipe-in-one is about the best bang for the bucks.
