Default Exhuast help

How easy is it to remove my exhuast font pipes, its more the bit that goes to the turbo... Do i need special tools? Is it going to be Half an Hour or Half a day?
I have an H.K.S. system but i dont think that matters, its only so i can take it off to weld up a split..any advice would be great.
thanks Stu...

There are 5 bolts holding the Downpipe to the turbo. There are probably tons of descriptions on how to do this in the archives here, but...

Basically, get stuff out of the way (intercooler, alarm buzzer, heat shield (lots of small bolts holding this on), etc.), then use a socket wrench, extension and 14mm sockets to remove the 5 bolts/nuts holding the downpipe one.

There are also 14mm bolts holding exhaust sections together and one holding the Downpipe to the transmission.

For a mechanically inclined person, it ought to take an hour or two.

Use plenty of Liquid Wrench. Those 5 turbo bolts took me a few hours.

Good Point. Turbo bolts and up-pipe bolts seem to be engineered to break easily. I sprayed them with penetrating oil the night before.

I've had 3 bolts that started loosening, then became stuck, then broke as the nut was forced off. Sigh.

The bolts & nuts are somewhat expensive. You might want to have a source handy in case one or two break.


Good luck,
Russ

2 were on the WRX, 1 was on the STi.

Luckily, on the STi, it was a stud that broke near the top, so there was enough left to re-use.

I'm not sure what causes a bolt to break when the nut is already free. My theory is that as you loosen it, the wrench applies uneven pressure, causing the nut to become cross-threaded. It might be worthwhile to swap these nuts & bolts with good quality replacements.

if the nuts are breaking the bolts/studs you could try wire brushing the threads before you start to get rid of any rust/grime that may have accumilated in the threads. also a little wd-40 (or other spray lubricant of your choice) applied to the threads might be helpful.

Most likely, it'll go smoothly. Just be prepared for complications.

Do you have a second ride in case you're left with a broken bolt and need to go get a replacement?

Again, it's a pretty straight forward job.

Good luck,
Russ
