My exhaust...

So I finally got my car into the exhaust shop that welded my exhaust together to begin with...

Back in Feb I got 2.25" pipe with only one 18" resonator and a twister muffler (very low tone) and a $70 Magnaflow tip... All that with labor was $200.... Then a week later my flexpipe failed inside (lots of rattling)... So I took it back to get it fixed... another 120-130... Anyways, it sounded beautiful...

A few months down the road I ordered xiaogary's header. Received it, installed it, the noise is even deeper, but a few weeks after installing it, I started hearing some "rattling" noise or some "clunking" noise that I narrowed down to being around the muffler area that only happened around 2K RPM... Checked all the "J" hooks and everything - nothing was close enough to rattle against the pipe (as was first suggested by the exhaust shop) at certain RPM... the only thing that I found wrong was a small hole at the bottom of the weld between exhaust muffler and exhaust tip.

Took it back to the shop so they can fix that and make sure nothing else rattles - only got as far as lifting it... Oh, we're emission certified shop, we can't touch a car without a cat. Get it off.... Went back a few weeks later, talked to them again... they said they would fix it if it was something they installed if I had the cat back in.

So last night I put the cat back in, drove it around for a bit, the noise was still there, but quieter. Took it to the exhaust shop, they found and fixed some leaks right around muffler area (the one found earlier and another one or two above the other side of the muffler). While they were at it, i asked them to throw in another resonator (to keep the car quieter when the cat comes back out), so they did... only $24 dollars... for the parts I come to figure out later... then labor... shop fees... came out to $98... (they said on the paper I saved about $100 I think, right....)

And now the exhaust is still low and pretty quiet with the cat in, but it sounds like I might need to get my engine mounts checked out, one of the techs said that one of them might be starting to knock when you "put a lot of torque to the wheels"...

But that will be another project for another day. For now I'm happy that my exhaust stopped rattling. Tonight will be replacing the stock header with xiaogary's header if everything goes as planned. And for now I'm going outside to enjoy some BBQ or ?????? (Shishkabob done the right russian way.. ;) )

fail

We have just a little more control over that little bit of toque that our Aveos do have with a manual transmission, something you would only read about on forums, hunter.

Thanks for your comment though. 8)

Now an actual question, do we have any after market options for motor mounts?

I was thinking about that.. Has anyone done that lately? If so, what filler did you use? Do you just go to an autoparts store and ask for some?

So I put the aftermarket header back in last night... Everything went in with no issues. The exhaust is a lot quieter at cruising speeds, but still has the deep sound to it when I give it some gas. Very happy with the result.

what does the butt dyno say?

Says the engine is "uncorked" without the cat :P And it's noticeably easier to accelerate... definitely noticeable diferenece above 4500 RPM

as others have said :) , ill have to get another one in september :D

another header??

i bought one like two years ago but had to sell it for money a day after it came in, the thread is still on here :lol: :lol:

Oh, I remember seeing it now that you said something... Don't forget to pick up some M10-1,25 bolts (40mm long I think) and some matching nuts since you won't be able to re-use the ones on the bottom of the cat. A cat gasket and exhaust manifold gasket are a good idea just so you know that nothing is leaking...

And don't forget the O2/vacuum sensor socket, its very handy.

Now your homework assignment is to record audio/video of it and post it for us! :D

You should talk to XJCasper about that... 8) Mine is already fully installed, and he is about to do his this coming weekend or the week after that. ;)

I don't have anything to get a video/audio clip.

I think pictures would be plenty with a good write up. In all reality, it's as simple as taking off heat shield (3 bolts), taking out the o2 sensor (specialized socket is very helpful) taking off 10 nuts on to of the header, 12mm if I remember right, and three bolts at the bottom of the cat (four if you count the one that holds the bracket that holds the cat to the block, helps to take it out to remove the cat).
To install it, just reverse the process minus the heat shield, it doesn't go back on. And you will need to buy three M10-1,25x40mm books and some matching locking nuts for the bottom of the header and a gasket too seal it tight to the rest of the exhaust. It's simple, really. And mostly self explanatory.

Once I get it torn apart, gonna head to town and replace the upper bolts and lower nuts and bolts.

All of the gaskets had to be ordered and are now in. Might happen on my next weekend.

Upper bolts? There are only 10 nuts and 10 double-sided studs threaded into the block with one side and the other side is for the nuts holding the header.

Hey serega, in your video on your profile you say that you have "gary's headers".
where did you buy them, and how much were they?

everyone buys thier headers from xaiogray, they will cost you about $4000 though, you can see them listed on ebay from time to time, well worth the money

hunterooo, the thing is its without the cat.. so id be screwed when i have to get emission tests.

Xiogary sells both versions. Get his short one I think it's even a little cheaper, and it retains the cat.

For the record, that is closer to $400.

Ya, there are two versions, along with a Turbo header.

Helps our weak engines, a little.

It's also noticeable at higher RPMs too (4K+) with the cat-less header. And for your emission testing you could get a blox CEL eliminator (extends your secondary O2 sensor out of the way) and you would be good. Or just keep your old header and swap them out if you're worried about passing. I have no CEL and I'm not too worried about it.... It's your choice though...
