Over the past few days before this incident my exhaust tone slowly got louder and more beefy. so, its Christmas day and im heading to my dads house. my exhaust start to get louder and i hear this sudden CLUNK!! my exhaust detached itself at the resonator and it was dragging itself on the ground lol. so i pulled it off.

i now have gone around 20-30 miles with it off and have used about a quarter tank of gas... Can anyone tell me what is going on here? Is it another problem somewhere? The local exhaust shop can only put on the smallest pipe of 1.5" on. will this totally kill my back pressure? will i need to add a CAI or something to make up for lack of power?

also i have another problem. I hear a ticking noise coming from my engine. it varies with RPM. Also when i start my car, it will go down to idle, then start ticking. and its loud too. after the inital ticking wears off, it will come and go at random. if i rev it up, it will come back down to idle and start ticking again. as far as i can tell its coming from the rear of my engine block. i need to get a sound probe to be sure. Could this be the fatal knock?

HELP MEH!!!

well back pressure is an issue. you need some not to much though. the ticking if it goes away with revs then you need lifters if its present a rev then your looking at possible bottom end problems. one way to discern this is to run down the road on flat ground. run it to hwy speeds, then back off the peddle a little then floor the peddle, then run a flat speed, that's not to add speed or decrease speed. if you hear something emanating at full throttle then its main bearings. if you hear something at flat throttle then its rods. or wrist pins on your pistons. hope this helps.

that tickin sound is a tappet. My spires done it for ages. Nothin to worry about.

As for exhaust. Just do it yourself?

Of course It could be either, we can't hear what you hear. Losing hla's is not uncommon, most times you get the warning indicators first though. Ticking at startup, but then they'll finaly pump up after a little while and quiet down. Eventually the seal is totaly shot and then they can't hold oil and won't even pump up at all, hence a constant ticking at all rpms.
It's pretty easy to find the bad one/s, if you remove the valve cover.
I'd remove the spark plugs as well, so the engine is easier to rotate.
Rotate the engine so the hla you're going to test, has it's valve in it's completely closed position. Now just push down on the top of that rocker arm with your thumb on the hla end of it, there should be no gap between the hla and the valve.
If there is, that's where the clicking is coming from, rotate and repeat with the other 7.
This does of course, not mean you can't have rod knock as well, but that's a much more expen$ive and labor intense process to address.
Think about doing a write up with pictures as you proceed and Good luck!

I have seen plugged PCV valves make some funny engine noises. Pull and shake, also check PCV vaccuum lines for plugs.

That is a really good explanation of how to do the hla's, I need to check mine and have been looking around at all the topics looking for one. Why did the car go through so much gas though? Where is the resonator?

It may not have to do with any of the things we've discused so far...he may have busted rings for example, and that's whats he's hearing, that would affect mileage.
A bad temp sensor would make it run "too rich" for example.
Guy's will come on here and not mention the check engine light has been on forever, but it won't be mentioned because the car was still moving and they need it to run "just a little better" you know, to maybe get to work a little more.
The muffler/res may have punched a small hole in the gas tank on it's way to freedom for all we know. Honestly, if you think we're good at this with "described symtoms" try to imagine being able to actually put hands on.
We got a guy on here discribes "some" of his symtoms like the "car won't idle" but won't mention (we find this out two posts later) that he also knows the intake is sucking in coolant from when he put it all back together badly last time, then wants to blame the car!
Hey, we try to help out where we can, but It is what it is.

ok so i was told by the mechanic i am shadowing that the ticking is a lifter. so not a real big problem there. nothing like "the knock" lol. it will be fixed eventually.

The fuel issue, i really dont know. im gonna start with the simple stuff. fuel/air filters for starters. if that does not resolve anything, then i dunno.

Also LangBardr, the resonator is between the cat and the muffler. it looks like a small muffler.

Also mouse i was thinking about doing an exhaust myself, is MIG an acceptable welding method? I do not have access to a TIG welder or even the skills to use it lol. also would 1.5" pipe with no cat be alright? or would i lose what little power i already have? and you gotta remember i have the little 1.3l american engine o_o

We need some real mileage numbers here, losing an exhaust system will not "half" your mileage, but A neighborhood kid snatchin gas will.
If you lost a lot of power and mileage, you may be down to 3 plugs running the car, but that would set a missfire code. Make sure you still see the check engine light at start-up, so we're sure the bulb's not burned out.

yeah i agree on milage numbers, but i really have no way to do that considering i only put $5 in here and $10 in there. i have no steady income so i put it in as i get it. im throwing in a new fuel filter tonight so we shall see how that effects things. ill make sure that bulb isnt blown out.

its funny tho, because there are no visible problems with my car. no smoke, leaks, anything! just weird crazy things going on. i cleaned my engine bay 2 summers ago, and it is still the same. (meaning no oil or fluids, a bit of desert dust, but thats it.)

Ok so i replaced my chocolate syrup fuel filter... Hopefully that should clear up some issues... Tomorrow im gonna throw in a new air filter and treat everything with seafoam. That should also fix my lifter problem somewhat if its just dirty. ill try to make a vid of stuff, but who knows.

And honestly, at times, i feel like i AM having a misfire, especially when that lifter starts clicking real bad. it just gets all sluggish and bleh. then it stops and i have normalish power back. we will see tomorrow after the seafoam if it needs replacing. Ill also pull the plugs and clean/re-gap them if necessary.

just take your original exhaust system and rebuild it using the same system to fasten it there

no i mean connecting the different sections of the pipe. should i just use a coupler and weld it together, or should i fab up a flange or something?

funny you should ask... My original system (still in use) is connected by the oval flange our cars came stock with. Keeping that flange there means open variety of interchangable exhaust systems such as tips and mid sections. But if you're going to do a permanent fixing then do what they do with the bigbore and run it continuously all the way through with no stops.
