I want a catback, but first of all I heard the piping should be 2.5" to b good. also, I dunno if headers will fit the exhaust cuz they never give u the exit size /:

mayb im jst too new?

another thing, when i search headers online i find some for like less than 200...is that jst real good price or real cheap products?

Popular header brands are MMW (Monster Motor Works) and Weapon R. Most headers are 2.5" outlet if im not mistaken, unless they are a turbo header. In which case they would probably be a 3" outlet.

You are going to want to buy a 2.5" piping exhaust, thats really most of the systems out there, unless they specify they are a turbo-back system.

If you do get a header you WILL get rasp. So go to a muffler shop and have them purchase and weld in a resonator for you. You're going to want 1 or 2 nice big resonators to take care of that rasp.

sont he magan pipes are straight im about to get the megan downpipe and s- pipe for like 280 and they give you 10 to 16 whp

I prefer the mmw header 4-2-1, comes with s-pipe as well. most headers are 4-1, which causes more rasp and smaller horse power and torque gains. I believe mmw header exit is 2.5in.

You'll never see 10-16WHP from that...

Plus you get all of the peak gains at the top end of the power band
