i searched around a bit and found a couple things but it didnt tell me what i was looking for.

i know some have problems with ebay headers but i have run them before without much problem. just wondering what the gain as far as preformance and sound im going to get out of the ebay header? i know its not going to be huge gain but i am looking for some. i have already pulled the mid-muffler out and replaced the rear muffler with a 5zigen i had from a while back laying around.

all opinions are welcome :clappy

You'll see a bit of a gain. Biggest issue with ebay headers is durability, which is really not that big of an issue in itself.

I got an Ebay exhaust on my 97 Ex 4cyln. Recent problem with the resonator, hoped to unbolt it last week but didnt get around to it, had a truck and a stupid nissan to work on first.

My resi appears to be rattling and I think the baffling has come loose. Sound is good aside from the rattle, durability isnt bad either.. However, I woudl highly recommend that you sand the entire exhaust system and spray paint it with Rustoleum BBQ grill paint (you know that super high heat shit taht goes to 1200 degrees) to prevent rusting mainly. I did it to my header but not my downpipe, which I regret. I actually cured the paint in my oven. + I had 3 coats on it ;) I used the flat black, I dont think the Satin is very good after seeing my buddys work on his nissans header. I reccomended that he sand and paint it, not only did he use a very fine(1000 grit I think.. I used like 280-320) sand paper, but he used a "satin" finish of the BBQ grill paint. We ended up getting some "break loose" penetrating oil stuff on the header and the paint melted away.

He had to drill the FUCK out of that header to get it to fit, mine slid on with no problems what so ever, the worst fitment I had was the hangers didn't line up perfectly and the flanges needed some work that I didn't pay attention to.

If you buy an Ebay Exhaust system I recommend bolting everything up with no gaskets in place and checking for any gaps between the flanges. You can use a flat bastard file to get a more exact mating of the flanges. Also you can port match the flanges and gaskets to get better flow(again something I didn't do) I re-used my stock Cat, which I didn't have a gasket for, The gasket they gave me for the cat was as worthless as tits on a boar hog. Should you get a full ebay system you'll probably need a new cat gasket from the downpipe to the cat( I was forced to re-use the stock gasket :/ ). The other flange of the cat and the exhaust system worked just fine.

If you'd like any other insight on Ebay exhaust for an accord please feel free to PM me. My exhaust cost me a grand total of 227 shipped.:w00tz Came with everything pretty much, except new headstud nuts, I bought them for like 6 bucks /w self locking flanges built in because castle nuts were hard to find.\

The main difference is the more expensive one comes with a test pipe. I say Fux that, they are both about the exact same thing. Honestly though it depends on what state you live in and where your O2 sensors are located on your current exhaust system. I didn't beat out my Cat because my O2 is mounted after the catalyst on the stock setup, fearing a CEL code I left it alone :)

When we unbolted the cat during my install the bolts broke of course, well we had to grind them off flush then get a steel punch and a hammer to drive the bolts out of the cats flange. Be prepared to take anywhere from 6-10 hours for the install if you encounter problems. Impact tools are highly recommended. Use penetrating oil or break loose stuff on all the bolts at least 24 hours in advance. If you can park the car for a few days and re-apply more every so often, even better.

You'll have to do your own research and inspection of the parts and setup on yours and compare them to the ones on Ebay really, I dont know much about 98-02 accords, other than they still use a F series engine. The exhaust should be similar, but as for 94-97 system working for 98-02 I don't think so. since my recent look up on Ebay, check this

eBay Motors: 98-02 ACCORD 4CYL L4 STAINLESS STEEL F22 EXHAUST HEADER (item 270377284208 end time Apr-26-09 20:33:15 PDT)

Flex pipe is in a different location for starters. Either way, get some PB on there and soak those bolts for a few nights before taking it to the shop. Like I said before soak em down good a buncha times and the longer you can let them sit the better. Your down the street mechanics will thank you. A new cat will cost a grip. Even more so for a "high flow" cat. Plus they'd have to weld a flange on there. As long as the stock cat isn't clogged youd do a lot better getting a tuneable ECU for your car, going OBD1 (on board diag 1 doesnt have a O2 after the cats)will allow you to smash that cats platium out to make it into a test pipe.. heck you can even recycle that crap. Better not do this if your state tests for emissions though :D

ECU's are a great investment as their value doesn't depreciate much either unlike other car parts. I recommend a chipped P28 ecu and conversion harness, I believe your car is OBD2b so you would need the according conversion harness. Don';t take my thought as gospel though, its up to you to check out the ECU and find out what the plugs look like on it to know exactly what ECU conversion harness to order should you go with an ECU instead of a high flow cat.

The only reason I'd suggest a high flow cat is if you went turbo.

EDIT:

Heres one for your model, Id think about buying that and making sure it comes with every bolt and gasket you need, then letting the mexicans get the old bolts out of the cat.

not really depends on the header. some can hurt performance. was it a 4-1 header or a 4-2-1 header. you won't really know how it will affect performance till you bench flow it against a stock header. then the car has to be tuned for it to see any real gains. hondas run map

Not all ebay headers suck...lol
for hondas they do

they see very little gains from "real" performance parts. why would a 50 dollar ebay header made by the 11 year old chinese boys 7 year old sister in a sweat shop give you any gains of a hyatech header

if you find you have a 4-2-1 it will be better then an ebay POS.

if you don't have a 4-2-1 - get one... it will be better then an ebay POS and you can pull it out of a junk yard for less.
