I'm having problems too. 1st of all I had to cut a piece off my to make the header fit. I installed the header and high-flow cat. My engine light went on. 1 month later still won't go off. I reset the computer, bought new o2 sensors, changed the position of the sensor and still nothing. I called hp racing and they told me that this problem has only happened to me. somebody help!

Somebody sells an O2 simulator that sends a fake signal to the sensor and keeps the light from coming on.

Aren't there 2 sensors, one before the cat and one after? hmmm...I have read about installation problems but nothing about the check engine light. Can you give some specific details about the installation.

[IMG]i/expressions/face-icon-small-mad.gif[/IMG] 1st I removed stock heaader and cat. next when I was trying to install the header, a piece of the motor mount was in the way so i cut a small piece off so everything would fit. the thing w/ the o2 sensor is that there are 2 spots on the header where you can put the sensor. I moved the sensor from the lower opening to the upper and used the supplied cap for the lower one. I reset the comp again and after a bit of highway driving , the light lit up again. just to rule out the sensors, I bought 2 new ons and installed them . reset the comp, and still the engine light returned. I 've contacted hp racing and they said I'm the only one to come out and contact them. By the way, their toll-free # is 1800-522-7855. I'm dealing w/ Frank. I must say that Frank is being very good abuot trying to resolve this problem. But I'm starting to get a littlr frustrated.

I checked my car out this afternoon at work I fixed the vibration the header was rubbing a bracket on the subframe so I just bent the bracket a bit the engine light was a catalyst deteriation code the high flow cat doesn't work as good as the stock cat I reset the light and it didn't come back on os hopefully it was an intermittant thing

So, how is the performance? Is it noticeable? Did your exhaust get louder or what?

I called HP today and talked to Rich and he said they are coming out with a computer chip that should solve the problem he said the chip will give us more horse power I think it will be simular to the venom 400

i have the 4.1 and the stock cat, bolted right on with no cutting or anything. took a floor jack to the front and jacked it up and put it on myself. performance? well it adds a lil towards shift points, id say 3.5 and up on the RPM

Hmmm...I have only read about fitment issues. I wish I would have bought the header now, but they didn't go low enough. You still have to mod the e-mount. I am waiting for the redesigned version before I buy one. Hopefully, someone will offer a GB then and from another distributor if we are lucky. I have never seen anyone handle a GB or business prop in such a bad and lazy way.

I have the HP header with free flow cat, mid pipe, and axle back exhaust. My light recently came on. Does not hamper performance. As far as horsepower increase goes, with all three peices, very noticable. i guess I will be buying the chip they will be offering. My only main problem is that I cannot get the donut gasket to seal well where the header connects to the freeflow cat, anyone else having this problem.

Then dont buy a car, because it requires gas for it to run.

ha! smart thinking. IT is a good point though. but hey, i was gonna get a chip anyway. If it fixes my engine light problem, smoothens out the exhaust tone and adds hp at the same time, than its all gravy.
