i am ordering my header and high flow cat next week. i am wondering if this is the right combination because i remember someone posting a while ago they got a magnaflow high flow cat and someone suggested that they had get another one. well i am probably most likely buying off of gravana and thinking about getting Magnaflow Carsound OBD-II Stainless Hi-Flow Cat, and Pacesetter Armor-Coat 4-into-1 Header. Will this combo throw any codes? and is that the right cat to get?
I like the 4-2-1 header better. You'll get a better deal on the OBX stainless 4-2-1 header on ebay, which looks better and you won't have to extend your o2 sensor wire. Also, as far as the high flow cat goes, I recommend the Magnaflow cat part number 53035. However, it's a 2.25" inlet and 2.25" outlet so it's best if you don't have a catback already to go ahead and have one made. I paid $150 for a 2.25" custom catback and the high flow cat installation... so just spread it out.

does the obx header on ebay come with the "down pipe" kinda thing? and is it ceramic coated or does that not really make that much of a difference in performance? also i just dont want things rusting out because of the winters we can get here in ct. and whats this about extending the wire? never heard of this before, but heck if its one less thing i have to do im all for it lol!

the stainless steel headers don't rust... stainless steel doesn't rust. ceramic coating does make a slight difference. The 4-1 header positions the o2 sensor in the collector basically where the header and b pipe join together. The 4-2-1 header has it in the stock location, but due to the header design, it can only get readings off 2 cylinders. It doesn't affect how the o2 sensor reads at all (at least I have not experienced any troubles with mine).

Do you need to extend the o2 sensor with the pacesetter on the ecotec?

pacesetter 4-1 long tube header tops the 4-2-1 headers...
4-1 short tube ....top end
4-2-1 mid range
4-1 long tube, whole powerband... best of both worlds
also reading from 4 runner is way more accurate than just 2, hence why pacesetter is carb approved.
cat converter, 94035, low profile so if you do lower the car, no worries on scrapping.
how hard is it to extend the wires for the pace setter header? what is involved in doing it.
cut wire, take other wire, splice in middle, solder... done.

my cat doesn't scrape, it's the catback itself that scrpes most of the time.

oh @!#$e thats not hard, cause im buying catback, high flow, and header and new gasket and taking it to a shop and telling them to have fun. guess they cant screw that up too bad.
event you say that the 4-1 long tube gives power through out the power band but obx's 4-1 long tube is said to only give low and top not much in the middle? am i just miss informed on this or is this correct? is the obx not as good of a header as the pacesetter?
ITS ALL FUN IN GAMES TILL SOMEONE GETS SHOT IN THE LEG
the 4-2-1 "shortie" header is for low end. however i noticed a gain throughout my entire powerband also

does obx even make a 4-1 long tube header. cause i found this one on ebay and im starting to wonder if its a fraud.
ebay header what do yall think

I doubt it look it is $43 to ship it, add that to the price and you are at what is cost on the average.

lil bit of comparison example....
http://tiger.towson.edu/~apittm1/header.JPG
4-1 vs a 4-2-1
yes i know its not our cars, but its a test based on design.
from what i understand from picking brains, reading, and real world examples
4-1 long tubes kinda act as the lower half of a 4-2-1 where its 2 tubes... the longer runners allow for the exhaust gases to gain velocity, which in turn increases torque.
pipe size and a few other factors come into play, but thats the rule of thumb.
im only lowered 1.6 so clearance really isnt bad. so would the pacesetter ceramic coat, and magnaflow high flow be a good pair off of gravanas site? no other issues or problems or extra things to do besides extend the o2 sensor wire?
nope. just make sure to not use an impact on any of your exhaust bolts.

hey thanks i think that im gonna go ahead and buy that header cause it looks like it would be a pretty good upgrade for my exhaust system.

go for it. the install is pretty straight forward and you shouldn't have any troubles.
