hey all I've been asking around all my local exhaust shops and I've got an average price of 1145-2100 for a full exhaust system with hi flow cat and a 4-2 -1 header. the problem is no one has any headers for Honda accord 90-93 models and they are charging me extra to custom make a set, what im trying to figure out is do i have an F22A4 header or not because if i did then the extra horsepower wouldn't be worth it, but my engine is a F22A9 (145hp) and i don't know if its cast iron or the tubular 4-2-1 design. can someone please help me. thanks

F22A9 I believe is similar to our F22A6. Look at your header/manifold. If it's a rough-cast piece of iron, it's not tubular. If it looks like tubes, it's tubular. Simple as that.
If they want to charge you an arm and a leg for a custom header (that will probably make no more power than what you have, since it'll just be slapped together), and you don't want to pay $1200 AUD for a Bisimoto header when they're available (which isn't yet... they'll be 600-700 USD, so after shipping and conversion, I estimate 1200 for you) I would just get a Megan Racing header. They can be had for $150 USD or so... and shipping can't be all that much... They aren't fantastic, but they aren't crap. If it costs you $500 AUD to get one, it'd be better than one slapped together by a muffler shop!

yer i looked at it. its tubular so no reason to get headers now right. if thats so then this is the cost im looking at.
high flow cat - 320
exhaust - 480
dual outlet - 200
twin tips - 300 for 2 sets
so 1300 all up. all mandrel bent and stainless and this shop has really good rep, i've seen the big 8's gain like 26kw and shit, so im guess for a quality cat back with the high flow thats an ok price. opinions anyone?

Expect no more than 10kw... probably more like 6 or 8, with your powerband shifted up in the RPM range. If you're going with a dual exhaust, you'll probably make less... might even lose power, as dual exhaust will cause a decrease in velocity. What diameter piping are you going to use?
(and for those helping out, he's in Australia, using kw and Australian dollars.
Kw = hp x 0.7457, and the current conversion rate for USD to AUD is: 1 U.S. dollar = 1.10926234 Australian dollars)

yes about the lose in power, i was concerned about that so at the Y-split the piping is to be reduced to 2 inch to prevent loss of power, i also have found a set of headers that i may be able to buy, the company seems pretty reputable and its not some cheap ebay company, the company name is Xforce i don't know if anyones heard of it here but on ozhonda and australian sites they give it some good ratings. thanks

haha yer one header im just used to saying headers . just wondering though, since all the i4's sound like bumblebees and shit, but the wrx is the only one that sounds different because its in a h-4 design, and the header design is like 2 one side 2 on the other, i was thinking even though it may lose power if i were to get a custom header made but instead of a tri-y design but like since the firing order is 1342, 2 ports from the header from cyl no 1 and 4 and 2 ports from the cyl no 3 and 4, so as the 2 from each go down they dont merge untill the end or something like that, hopefully making it sound non fart can bumblebee etc. lol i know it sounds stupid and would probably make you lose power but does anyone actually think this will work
