ok i dont think many people are awake here...

but has anyone changed or removed a catback exhaust on the corolla? im trying to get the two bolts off up in front of the firewall, but i just cant get to them enough to apply sufficient pressure to get them undone... they are done up so tight!

anyone know an easy way to get them off? i dont wanna pay someone to do it if its just a matter of unbolting it and bolting it back on again...

ugh... i got the muffler off with enough force... and they were alright...

but i cant get these ones off!! its driving me insane that they are just bolts, nothing worth paying to have done... but i cant get to them!!

everything is so awkward and the stuff that shields the pipes is this thin sheet metal, and ive cut myself open twice now...

stupid cars...

yeah cos i put the stock muffler back on to drive to jason's place and pick up his ramps...

so its all still in one piece, and ive spent my whole night lying under my car trying to get enough leverage to get these bolts...

lame lame lame...

time to start saving somehow i guess and get it installed by someone who can do it...

spray it with some WD40 and see if that helps?

its a two way bolt right?

so u need a spanner to hold the one end while you loosen the other.

hacksaw? steroids? (to help you get the strength to undo the bolt)

:P

just joking mate, i don't really have anything constructive to add, except, try getting a longer spanner so you have more leverage and also, make sure the bolt is not welded... :P

tom ! ... just listen to me and wait till saturday when we go to the exhaust place ...

they will have it done in a jiffy and at least there is some kind of workmanship gurantee

As pete said .. im sure that there is some kind high temp sealant which is applied ... and there is no way you will be able to get the bolts as tight as they are ...

and there has to be some welding anyway ...

so hold your horses ... its only 3 more days ..... do work and get a few $$ ....at least he can quote you on sat so you know how much you are up for ....

I got my cat put on and flanged so i can upgrade later for 70 bucks.

I remember the stivo zort i got was 2 inches short of the 1ZZ cat and its pointless cutting the stock pipping 2 inches frm the cat and welding it there as it will go from 1 3/4 to 2 1/4 after the cat so it would be worth nothing.

SO they basically got another peice of 2 1/4 " pipping and added onto the stivo cat and the flange so it's a full 2 1/4 inche from the cat right though.

The guys that did it for me are AutoWorks Plus on the hume hwy lansvale or cabramatta. cant remember what suburb it was. Around 10 minutes from the villawood meet

Spray the bolt then the easiest way to get it off is use a very long extension(like about 2-3 foot) and then put the rachet on and away you go. that's how I've always done as it gives you more room being out of the tunnel but if you don't have the tools then I'm sure the local exhaust bloke will have the kit to get em off :D

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
