yeah, just call Hogan and ask to speak to da man himself: Kurt Hogan, he is the one responsible for all orders and manufacturing of the DP's, he will set you up real nice, the kit comes in a long box with all you need. You will have some newspaper as packing material and your gaskets and flanges will be in a envelope taped to the side of the box labeled with marker, "Gaskets and Flanges". Your Downpipe will come in one piece half-way bolted-on for packing and fitting...gives you an idea of the direction it goes etc....thats if you buy a HF CAT with your set up....the shorty DP is just one short piece that is ideal for 3" back all the way custom exhaust....I dont recommend that though as there is such thing as too much exit flow...keep the ratio from the front as 3:2.5:2.25 to the rear in the muffs...just opinion...do the cardboard paper towel roll or gift wrap tube experiment I tell to guys for flow questions....you have to keep air tight toward the rear for a back pressure figure to help your HP...blow into one of those, and ill bet you get winded really quick...now place just a lil smaller one at end inside to constrict the flow, you will see smaller constrictions will "pinch the air" as this keeps ya flowing well and doing someting with the back pressure which means your not just cycling air out the rear...this is just my opinion though...lol
ya ill be getting the highflow cat. thx btw, great help man.

Ok, here's the deal to avoid a code with a new performance downpipe. Get a O2 Simulator. Check the web, there are a lot of electrical ones out there. Or... this is supposed to work: a mechanical simulator. http://www.s2ki.com/forums/index.php...9&hl=simulator Although this is not on our cars, I have read about this on other sites with various types of cars and everyone who's tried it says it works and it very cheap and easy.

Well one can't even buy the OR DP anymore...so that sucks. I looked into the CA law and the car has to been 9 years old to physically touch the cat, whether a OEM replacement or a new DP or the like--you are facing a $1000 fine per cat if you tamper with them.

I don't think it has ever been legal to remove a non-faulty emmision device period. I only removed mine because it was ummm defective. Kurt at Hogan Performance will build you the highest quality product you can buy, hands down. An HP Tuner will get rid of the light if triggered (not all cars trigger a light - mine took 2+ weeks and happened "off road" at 130+), but the downside to not getting it tuned if the engine light comes on is the Auto Start will not work, and you will not pass your state emissions test (if required) because once they plug into your OBD port, it will register a faulty CAT/O2 sensor and you'll get the big ol "R"ejection sticker. With the HP Tuner, you'll pass without a problem, and with Flowmasters these things sound great.

Don't roll your eyes at me! Just stating it's only in emissions counties. He can get an inspection in another county, just with an affadavit, which will only get you into trouble while back in Houston.
I'm glad here in Bell county we don't have emissions yet.

Vector Motorsports has a tune for $369 that is 'stealth' and they can remove the light. You can opt for HPtuners which costs more, but is much more capable.
There are some other tunes available also.
*edit*
I've read that spacer type simulators don't work for our vehicles due to the 02 signal being varaible, and with the spacer it gets a constant reading.

Once you remove the code with a tuner, while using the Hogan DP7S, will the code return? I just installed mine 3 days ago. No troubles yet, but it sounds like this code is inevitable. Thanks for any info.
