Put on an exhaust pipe 2 1/4 from cat back and aftermarket muffler. The mechanic asked if I wanted the resonator taken off and I said sure. I think he took off the Cat and left the resonator on! My understanding was that the resonator was right after the headers and the Cat was further back from the resonator. He removed the second one further back on the car (the one I assumed was the Cat). The resonator he gave me was a large metal object that could have passed for a small muffler. So I think my Cat is now off my car and I can get into a lot of $h!t. So was it the Cat or resonator?????

Forgot to ask, does it sound nice, and notice any difference? Also how much did it cost, I am still searching around for a good shop, and I would like to know how much you paid so I will be able to compare a little. Thanx

The resonator is pretty far back from your header. Its a "bubble" in the piping for your exhaust, about 1 inch wider than your regular pipe. The two big things you can see down there are really a cat and precat according to the mechanic who did mine.

The part removed is approximately 6 inches wide and 15 inches long. It was located approximately 4 feet from the engine. Is it the cat? or the resontor?

As far as the price for the 2 1/4 exhaust from cat back was $105.00 which included install of aftermarket muffler. It sounds good not too loud and is very smooth. The power gains seen are in the upper RPM range from upper 4's to red line. Can tell a slight difference. The only true way would be too hook it up to a dyno. Going to be installing headers, BTB, and CAI as soon as they arrive. Then the larger exhaust potential will be utilized. The exhaust work was done in Pa. at Mr. Muffler.

Thanx for the info on the pricing. 4 feet from the motor and 6 X 15, you got me...unless I look under my car and see what you are talking about. Ok looked under the car and then looked in the owners manual at the diagram and from what I can come up with, that is your CAT. Says it right in the owners manual in section 7-1.

I guess I should have looked in the manual as well, sometimes I just don't think. That sucks now another trip back get the resonator off and the cat back on. I definately don't want to get fined for having a catless car!

If it has a casing on it then it was a cat. If it was your exhaust with a bubble then its the resonator.

Put it this way, does this thing look like it was welded on originally or does it look like the car under your head in the engine capartment. If it looks like the cat under you head then he took off the main cat converter for your car. Both cats look almost identical so you should be able to tell.

I just went outside and looked under my car and I don't see a resonator at all... Check this out though:
http://www.hmaservice.com/xml/graphics/EC/ECFA091A.gif
this picture is a diagram of the 2000 1.5L exhaust system from hmaservice.com. There is a catalytic converter listed, but I thought the one they have as the cat was the pre-cat. There is a "center muffler" also listed. Is this the resonator? The pipe doesn't bubble like it must on the x3 Accents. I am assuming the unlisted big bubble in the middle, between the muffler and the manifold is the main cat. Am I right?? I don't know anything about anything with exhaust and I plan on having mine put on this weekend. (2.25" pipe from cat-back) I don't want the shop cutting off my cat either! Someone who knows what they are talking about please clear this up.
Thanks alot!

Thanks for the link Treybrad,

Yah the middle muffler is the one that was taken off! I didn't realize our cat for the 2000 was around the engine (exhaust manifold). How can I put on my aftermarket headers without getting rid of the Cat??? Man I'm getting confused! Taking the car to the shop tomorrow, hopefully they can clear things up...

Hey Doc,
when you say the "middle muffler" is the one that was taken off... do you mean the "center muffler" as indicated on the picture or the big bulge in the middle of the picture?? I keep getting more confused!!! I just asked a friend to look at the picture and he says the "front exhaust pipe" is the resonator.. That looks kinda hard to replace to me... Is he right???

Treybrad and others...here's the deal! The cat is located right after the manifold in the engine bay about 8 inches from where the gases leave the engine. There is one O2 sensor before the cat and the other O2 sensor after the cat. So you can take every thing off after the bottom O2 sensor and it will not be the cat. FYI Aftermarket headers will cause the removal of the cat therefore another one has to be installed. In the states you have to have an O2 Sensor before and after the cat. I hope this clears up all the confusion (my bad).

Lantra...this garage will do anything you want them to do, even remove a cat. <b></b>

Thanks for clearing it all up! Does anyone know what the thing labled "front exhaust pipe" is?? And if everything after that first cat on the manifold is able to be taken off.... that is one HUGE resonator!
thanks

basically, I went to the dealership and made the parts guy look all this up on his computer. In case you really care, Doc was right... there is only one cat and it is right after the manifold. The section of pipe in the middle with the big bulge that was in question is indeed a resonator. The whole middle section of pipe new from Hyundai is only $150 or so, which is way too low for a cat anyway. They couldn't tell me what the "front pipe" thing was though. Hope this helps clear things up for sure.

Hey just to let ya know, when I had my car done, I got the 'flex pipe' replaced. It is by the engine and it looks like a chain-link fencing kind of. Its also flexible(duh!). Just my 2 cents.<img src=icon_smile_tongue.gif border=0 align=middle>

ahh.. that must be the "front exhaust pipe" is. What does getting this removed do?? Is it restrictive, or would it be a waste of money trying to get them to remove it??
