Scottydunno Posted May 28, 2019 Share Posted May 28, 2019 So, I finally got the time to install my long acquired catted downpipe. Any advice for the bolts/nuts? Mapp gas torch??? Scotty Link to comment Share on other sites More sharing options...
Notorious Posted May 28, 2019 Share Posted May 28, 2019 Don’t forget a socket for the O2 sensor. If you live in a rusty area, I’d recommend an O2 sensor socket over a wrench. Try to use liquid assistance from WD40/PB Blaster first before torching it. It’s not too difficult. Good luck Link to comment Share on other sites More sharing options...
awfulwaffle Posted May 28, 2019 Share Posted May 28, 2019 I have recently become an AeroKroil convert after it allowed me to push 180k mile axles out of the hub splines with my finger. Link to comment Share on other sites More sharing options...
AWDFTW Posted May 28, 2019 Share Posted May 28, 2019 How much rust we talking about? For minor to moderate I'd apply several applications of Liquid Wrench or PB Blaster to all hardware for a few days. Tap the heads a bit with a hammer on anything you can reach, should help crack rust and help the penetrant seep deeper down the threads. Link to comment Share on other sites More sharing options...
jrho Posted May 28, 2019 Share Posted May 28, 2019 I recommend using penetrating fluid on the bolts the night before you plan on doing the install. At almost 150k miles, I managed to take off all of my bolts and nuts for the install without any issues Link to comment Share on other sites More sharing options...
Max Capacity Posted May 28, 2019 Share Posted May 28, 2019 (edited) Use anti seize compound to on all the threads Any 3/8 nuts and bolts will work for the mid pipe connection I also like to pick up new nuts from the dealership and remember not to over tighten that one nut under the DP in the stud in the turbo, it can be a PITA to remove if over tight.

The turbo was replaced before I bought the car about 3 years ago. How long before that, I'm not too sure. It's definitely newer looking than anything else! Solid advice everyone. Thank you.
