Cheers guys for all the help and info, much appreciated. Will check out ebay.. This redback cat has a OEM grade ceramic honeycomb substrate. Not sure what that means, is it best just to avoid that one because of the ceramic substrate? is that the same as a ceramic core?

EG, on lowered cars the cat or exhaust can get bumped and the jarring effect can stuff the cat and break the internals. On a metal core cat, its more duable being metal of course but cheap ones are known to fail under heavy loads (turbos etc) So a decent metal core cat, 2.5 inch 200 cell should suit you fine. Yeah i'm planning on getting it lowered eventually. Cheers for helping mate. |

Something like this will suffice http://www.ebay.com.au/itm/High-Flow-2- ... 415e2b94c5 Never heard anything bad bout the brand so must be ok Yeah looks good but will it need welding? Got no mates that weld and i have a budget of about $400 So might just have to go with standard  as much as i'd love to get that one..

epic four page long post and nothing has even happened yet...
I've got one of those loboka cats, they look shiny when they're new, seem to work fine but they do smell in 100cell. I believe the factory spec is 250. yes it will need welding, I would suggest, if you already have a 'cat back' then invest in a set of extractors & a cat, take them to the local exhaust shop and say "flange this cat one end to match extractors, install extractors & do one single weld back into the original system". Then you're away with more power than ever. I give this advice as a professional welder/fabricator: exhausts suck balls. Exhaust places are set up for that kind of stuff and if you find the right one it's only a matter of a cheap cashy. Don't stuff around trying to save money with second hand shyte, in most cases it will cost you more in the long run.

UPDATE: Got a 2nd hand cat from the wreckers. The plan is to get a new set of extractors and high flow cat when i have the cash to spare. Installed the new cat yesterday only to have a look over everything with a flashlight and discover its leaking where the cat connects to the extractors so gonna pull it all out today and try again.

Yeah i thought i used the same gasket, didn't come off when i took the old cat off.. Didn't even know i needed one haha. So where does the gasket go? Just inbetween the cat and the flange? Sorry about the questions, bit of a newbie haha. But felt pretty good being able to do it myself haha.
Yeah i have the same set up, lukey 2.5 cat back but found a small hole so looks like that will be the next thing that gets replaced. And thanks for that buddy, ill grab the WRX gasket and should be cheering. Yeah i rang on friday and got quoted $180 for it rang a different one and got it for $90 so was pretty happy with that. Is the car ok to be driven the way it is? Just say dad wanted to take me out for a lesson for an hour or so? |

Cost me like $5.75 or soemthing like that from Auto One Carlton. Was cheap. Can use car, in fact be a good chance to get under it, do the drawing/outline and put it back together and go for a drive to numerous shops. If on L's, will chew up some time for your hours. As far as the hole in exhaust, can get below stuff http://www.supercheapauto.com.au/online ... escription Yeah will jump under her and see how i go. Good idea cheers mate. Looks like ill be off to super cheap auto when i can get into town  Awesome, Absolutely love driving haha especially that car.. so ill see how i go getting this gasket out.  Hahahaha awesome Yeah see how we go, muffler seems to be making a weird noise and its like there isnt enough smoke coming out the back end. So not sure but think she might be cactus. Was also sitting for a while and had a bit of water come out the back end on cold mornings. Thanks for all the help & advice mate.

Water in exhaust is normal. once warm should be right. As long as it isnt blowing white smoke then you are ok which means headgasket leak. Blue smoke is valve rings and black smoke is rich but under WOT(wide open throttle) thats normal If gasket isnt sealing, the gases will try to leave via less restrictive point in the exhaust, hence leaking gasket and hence not much gases coming from exhaust at the rear. My exhaust leaked from the joins, you know where the muffler meets the rear and cos was slightly rusted together and couldnt be stuffed taking it off, used the exhaust leak stuff. Is weird fibro kinda stuff and you need to secure it with wire until it gets to temp and melts into the holes/leaks etc. Works a treat, smoked a bit though and smelt until it sorted itself out but follow instructions. Just got under the car undid this cat from the extractors and theres no gasket in there! Also had a look on the old cat and nothing! So im thinking it was a dodgy job to begin with, looked everywhere and cannot find the gasket. Yeah wasn't sure if it was normal, but also sitting there with the water in the exhaust would have contributed to the rusting and that would be why i have a hole now. Think ill need to use the exhaust leak stuff too, noticed where the cat joins to the muffler shes leaking a little. Thanks for getting me onto it

alot of the time with 2 bolt flanges, particularly the thin ones on factory cats, the 'ears' end up bending forward over time, leaving a gap in the two quarters where the bolts aren't (top and bottom), if that makes sense.
you can check this by putting a straight edge on the flange, then band aid by tapping the flanges back a bit past straight so they have a bit more clamp when tightened. permatex make a propper exhaust flange sealant, it's your friend on second hand systems, still need new gaskets though. I also found commodore gaskets fit my 2.5 inch 2 bolt flanges. Always best to take a sample in like uniacidz said though.

Yeah i was thinking of just taking the old cat in with me when looking for a new gasket? Just to give me an idea sorta thing. |

Yeah best way to go i reckon.. i have no idea if the old gasket simply corroded and fell apart or what happenned but looking at the cat i pulled off bosal aftermarket piece of s**t looks dodgy which is surprising as the previous owner was a mechanic at kmart tyre and auto

Bottom line, Don't trust Kmart haha. Atleast now this xr will get the love that she needs looks like i saved her just in time then haha.
