Borla exhaust install
2000 A4 1.8T 155K miles - The daily driver that will soon have an exhaust....and chip.
I got a leaky exhaust flex pipe last Friday. I figured the rest is gonna go sometime anyways, so Iordered up a Borla 14845 cat back (delivered last night) and picked up the gasket at the dealer this morning. I did a 3 inch cat-back on a friend's EagleTalon AWD about 5or 6 years ago,andit took all of 30 minutes. I'm experienced at doing this kind of stuff.
But this A4 has got 3 rustednuts/bolts that are a PITA to reach by any means. I hit uptherusted threads with some liquidwrenchthis afternoon after work. I got2of the heat sheilds out of the way so far,and still have a tough time getting a grip on the bolts at the back end of the cat.
Has anyone here done this themselves before? Is there something else that has to come out, or some other way of doing this.
I have tried to get at the bolts with 2 feet worth of 3/8 drive extensions and socket. The size is 13mm on the bolt/nut, is this correct?
Is the attachment hardware a nut and bolt, or a bolt with a nut welded to the flange, or a stud welded to the flange with a nut on the other end...?
It's rusted so it's hard to tell.
I don't plan on replacing the cat yet, so i don't want to mess stuff up to much.
Any advice from anyone who has done this would be appreciated.
Thanx,
Bogie

) and try an impact wrench... lol though im not sure if it would be convenient seeing you need all those extensions.. but impact would probably be the best.
