Question Exhaust system help?

-----2004 Ford Focus ZX5 2.3L Duratech 4sp Automatic Hatchback-----

I know there's probably a zillion threads with everyone asking, but im gonna ask anyway because I'd rather have a thread personalized for me and my specific model/trim/year

My 2004 ford focus zx5 is LOSING its exhaust. the speed bumps where I live are probably about 4 1/2" high because the landlord is a re-re so I bottom out constantly (and im not even lowered) so after finally getting the sh*&$ of bottoming out the weld that connects the hanger on the muffler broke loose. so i have it hung up there with a coat hanger for a quick emergency repair.

Im looking into getting new full exhaust system (but no headers)
I don't want to break the bank because most of what i see is upwards or $500, which is ridiculous.
So i'm looking for an exhaust at LEAST below $300 i don't care if i actually get better performance than my stock, but a deeper sound would be appreciated (not ricey)

Also: anyone recommend any Short-Ram intakes for cheap? i don't want to shell out $219 for one.

If i change the diameter of my exhaust from 2.25 to 2.5 would i have to change my headers? or would it just be "recommended" ???

Any help would be greatly appreciated, i'm open to criticism too.

And yes I do get too lazy to capatalize all my I's [bootyshak

to start, its header*

secondly, are you sure you have a 2.3L? IIRC there was some pzev models but i wasn't aware that they came with an automatic option in the hatchback, in either case if you do have one you lucky sob!

as for intakes you'll probably find steeda short ram to be the cheapest used off the BST.

i have 2.5'' on my car, no need to put in a header, you can if you like but i warn you its the biggest PITA you will ever encounter if you decide to do it, particularly if you wrap the header. mbrp/trubendz should be on the cheaper side compared to the rest of them or you can even head to your local muffler shop and see how much it'd cost to have one made.

and if you want some more responsiveness a new throttlebody helps on the automatic a lot, i should know i have one.

start looking for a used system. Two, new, nice mufflers are going to run you close to $200. New pipe is going to run you close to $150. then labor to install.

...and try taking the speed bumps at angle. I am sure you have more than 4.5" of ground clearance with your exhaust. I am lowered 1.5" and have more ground clearance than that.

yeah it is a 2.3 (i found out after i purchased it) i have ZERO interest in changing out my header* unless it goes bad on me. considering how little "wiggle room" i have in the engine bay.

I had a helluva time trying at my alternator. got it halfway out and ran out of sunlight and gave up. It has bad voltage regulation so im worried it will negatively impact my battery in the future, but no problems as of yet, so im ok with slightly flickering headlights and interior lights.

Thanks for the advice guys, it means a lot to me. And i always try to do my own labor on my ride. Unless its something im not comfortable with, or dont have the time for (like ripping apart my engine block in the street...never again lol)

For lower price, either ask a few muffler shops to fabricate you one or check out http://www.mandrelexhaustsystems.com Of course you usually will get what you pay for, some have had small fitment issues with the site i linked to.

just look for one that says its for a duratec and zx3/5, should fit fine.

do what i did. go to an exhaust shop that carries magnaflow mufflers tell them you want a 2.5" flex back system. If they cant do that because of your secondary cat (If you have one, I did) then get it from the secondary cat back. I had mine from the second cat back and i noticed a small increase in power and a nice low noise deep tone. not ricy one bit. I later removed the secondary cat and replaced with straight pipe and i love the sound now better. little louder and a few more horses came out of it! either way a 2.5" magnaflow from a shop will be muchhh cheaper and they sound awesome!

Oh by the way I paid $220 for that system. So sounds do-able for you :)
