OK I've decided on Kooks long tube headers, a rotofab intake, and a superchips cortex, i need to finish my order.....
And i think Marylandspeed is about the best price on everything but do you think they would give me a one big order discount. MARYLANDSPEED hint hint.... please

That being said I like the Corsa note but i hear they won't go with the longtubes. so what are my options. I will not comprimse on the Kooks long tube and rotofab and the cortex so don't try and change my mind or give me your oppion on those components I just want info after the header. Thanks for the help I know I should get some good oppinions on this one. oh and I drive at 70 to 75mph to work everyday for 30 min each way with 2 other people in the car. so nothing crazy loud at that range

You might want to get a custom tune with header's. Because it will throw code if you dont. I know mine did.

What setup did u have? I'm thinkin maybe full kooks with catted x pipe. Would that throw a code? I'm also keepin the long catted slp's in mind too, any feedback on those with a corsa.

Yes the long tubes will throw code for the rear O2 sensor I believe.
I would go with Kooks long tubes and X-pipe with stock mufflers.
Also go with OTR CAI, like the Varam CAI works best.
Just my 2cents...

so no matter what cooks long tube will throw error. That's part of the reason i'ma get the cortex at the same time

I think all header's would cause it to happen.

something I wanted to try but since I already have my LT's is kooks mid lengths with a corsa catback. I'm running with Magnaflow axlebacks and if you drive 70-75mph the drone is bad.
