S5 Fan thing?

 

that pic is awesome !

 

I ususally don't tell ppl to search, but this **** gets asked every other day. Search for beefy n/a

 

This would be the first clue: "i also need to buy new mufflers and a y-pipe". This is also called a "catback" exhaust because it includes the exhaust components from the catalytic converter onward.

Here is one example of a good catback:

do yourself a favor. Decide how much you want to spend to get the power numbers you want. That might convince you to start with a t2 instead of a NA right from the get go.

 

so u want stock ports or bigger ports?

 

If you can't have forced induction, the next best thing is porting. If you can't have porting, the next best thing is exhaust. Intake would be next, then slightly advance the ignition timing from stock settings, get an S-AFC or lighter wheels, do some weight reduction.

I love this question because it is so easy to answer.
