is something wrong with the car? Do you have inpa OBD2 interface? Connect and check if they are working in specs.

Depends on what has been done previously. Are you going to DIY or have the service done by a shop?

I want to weld new tips onto my 3.0i... Do I have to remove bumper or is it better to cut off exhaust and put it back again?

The risk is fire or melting something and the gas tank is nearby. Your call.

cyclone filter, plugs, all fluids, (f+R transfer box) gearbox, been changed, rear sub bushes,the list is huge
I just thought there might have been some components that just fail after 153k miles, that just arnt failing but could do with changing

What is the exact size of 4.8is exhaust tips? Thanks.

Hey, trying to take my coilovers off and put air suspension rear back.
Problem is i threw my old gas shock that sits behind the airbag away.
Queston i have might seem dumb but can i just install the air shocks or will the pop? I will not be driving my car anymore.. juat needs to make it on a tow truck

If the airbag is in decent shape I would do it.

Eh it doesnt leak i dont think...i pumped it up yesterday it was rock hard.
If theres no air in and compres the bag theres alittle bit of pitting or little aging near the bottom..
I can take a picture if needed.

But i just dont want it to explode, does the gas shock take weight off the airbag or does the airbag do most of the holding?
The gas stut just to smooth it out?

lmk if you're selling the coilovers
