I would get the T-5 pipes. You will end up wanting to get it ported soon enough. Trust me!!!
As for the shocks and a-arms.
All you need are the a-arms and the elka shocks. You might beable to use the stock brake lines not sure. Eather way the stainless brake lines preform and look better. If you go with the wicked a-arms.( thats what I have and love them) dont buy their brake lines. Get them somewhere elce.
With the elka shocks, you have to make sure that they are valved for the +2+1 a-arms
