Help! Need exhaust opinions!!
 

Ok. So I want to upgrade my exhaust. Now, with the excess air coming in, I know I have to compensate for the fuel. 550 primaries and 720 secondaries with a rtek 1.7, and walbro pump should cover it, if I am correct.

If I am going to piece everything together in words, I would need a pre-silencer(maybe a RB), downpipe, mid-pipe, to cat-back exhaust(maybe the rest corksport?). I just want to know if that's all I'm going to need? The one mod to the engine is that its street ported, and that's about it.

I know this is a redundant question, but can someone help me out? I want to do it the right way.
