There is actually quite a few options as far as price, look and functionality goes. You can do dual exhaust (like mine), single drivers exit and single passenger exit. Corksport IS the cheapest and is really loud. Apexi is popular and priced reasonably. All depends what you are going for. Headers are really nice. RB is the only way to go really. I have heard OBX makes them now but not sure how they stand up to the heat. Pacesetter is crap. Don't get they're headers. You can aslo do a staight pipe (no cat) or a RB test pipe. What are you looking for?

im basically looking to get the most hp i can with a non turbo

The most horsepower with bolt ons?
Or are you willing to open the engine?

for now im just looking for the most hp i can get with bolt ons.

your biggest hp gains will come by using the search function up there

Okay, i have a RB test pipe laying in my garage, on my car i have a borla cat back, and RB headers, how loud would this be if i added the test pipe? And if i already have my ports hooked up to work off my air pump would i be loosing to much back pressure just from the engine? I understand that my ports have nothing to do with my exhaust now, im just worried that if it flows to free i might lose some torque. So confused and curious

P.S.
Obviously i have an N/A

the n/a like a lil back pressure, RB header and a custom cat back (your local exhaust guy) is the cheapest way to go for a few more hp

alright i think im going to go with a racing beat header for now but i read that you can only use the header on and engine with a carburetor intake system, and somewhere else i read that you can use the header with and upgraded fuel system. does this mean that if i uprgrade fuel injectors or a fuel pump that i can use the rb header? or should i just go with a cat replacement pipe instead of the header?

j0rd4n

ummm...you can use the rb header with the stock fuel system, that's not your bottleneck at the moment. i don't know who says you can't...
