What are some bolt-ons that im missing on my car that can create more power?

 

Test-pipe, 02 housing, tubular manifold... just off the top of my head.

 

02 housing,ported exhaust manifold,licp,front mount ic + retune

 

o2 housing make a big difference? i thinking about purchasing the megan manifold and 02 housing

 

The o2 housing is good for like 10hp.

The megan manifolds have had cracking issues usually i just tell people to port the stocker.

Also may i add to that list:

- Test pipe / High flow cat
- 20g turbo (still considered bolt on)
