okay i just got an test pipe that i just got that came in today. i'm not so sure if anyone out there has one also but it seemed that the screw that botes onto the header and the pipe needs to be longer or not? also how the hell do u take out the O2 Sensor off from the cat. Help me out i don't need no BS people

 

If you can, you should try and re-use the 2 OEM stock bolts that are already underneath where your headers mount like in the picture to the FAR LEFT(not short ones included in your kit; sometimes they are too short). Where you need to loosen it looks like an elongated oval shape with 1 bolt on each side. You will have to access them underneath the front of your car while it's on a lift or jackstands probably removing your black plastic splash shield, being careful not to break the bolts when you loosen them. Make sure your downpipe (I'm guessing you're calling it a test pipe), has an intergrated cat. converter built into it for passing emissions. You have to purchase a special socket for unloosening the o2 sensor cause of the wires, etc. Make sure your car isn't totally cold, you'll have a hell of a time loosening the sensor. Warm it up for a few minutes then turn it off so the pipe isn't contracted from the cold. Put some anti-seize compound on the threads of the sensor so you can get it off again. Your new downpipe will run from directly underneath your headers to the middle of your car underneath, bolting on the other end in a triangle pattern (3 bolts). Hope that helps. It probably looks something like this I'm guessing....

 

is this pretty much a bolt on removing the cat or it bolts up before the cat?>

 

You unbolt the cat. from the header and mid-pipe, remove it, and replace it with the test pipe.

 

dont want to ask a dumb question but is there any major gain with this?

 

Besides a slight noise increase (and the issues that come without having a catalytic converter, aka. passing emissions and "tricking" the oxygen sensor into thinking there's a cat. so the car runs right), no there isn't any gains.

 

okay today i got it in but the only thing that i'm having trouble is the gasket where it sit on the header and the pipe is to big. (came with pipe) so i just had to put on the one that came with the car. Now is there any way that i can get a Strup Angled CEL Eliminator where the o2 sit because the check engine light comes on. OH i have an dc header on and it seemed that when i drive the car it look like the car is leaking air or sound like it an swap. i don't know but if this happened to anyone before let me know how i did or so.
