Default IS500 GTHAUS Exhaust Installation

Hey guys just got my GTHAUS full cat back exhaust in the mail! im looking to self install instead of taking it to a shop. anyone have any advice, videos or luck installing it on your own? I dont have a lift nor a garage of my own to do it in. IF someone has a video this would be most helpful so I can watch the steps of install. Also any additional items needed other than what comes with the exhaust in the boxes?

I had a friend's shop install my GTHaus exhaust. They've got extensive tools at their disposal and still had some minor issues pulling the two O2 sensors out because of the positioning with the O2 sensor covers. They were able to get them out though and everything else was pretty straightforward! My setup is valveless, so I cannot comment on the wiring setup for those.

It’s posted on the is500 owners club page on fb so it looks like I can’t link here unfortunately. I can’t upload here either as even a 30 second clip is exceeding the file size limits..

The only tool to use for proper safe removal of our O2 sensors..

22mm crowfoot design socket.. Do not ever cut off the heat sync / shields..

I wanted to get GTHAUS LSR cAt back pipes but it says if removed the secondary cats….to my knowledge if I do that it won’t pass emissions. Am I missing something? I thought it was illegal to remove any cats off of a vehicle.

I am looking at just doing the mid pipe to my vehicle but I am not sure if should do that or the axle back instead.I know the current exhaust is to quiet for my liking! Please any help choosing would be great !!

Both are pinch points in the exhaust.

Maybe start with an axleback and see if you're happy with that.. then if you want it louder, add a resonated midpipe- or wayyy louder, do an unresonated midpipe

I was thinking about going this route and just doing an axle back. Does anyone have any sound clips or know about the sound level?

I have clips of the full exhaust on my instagram- I think the little IG logo to the left should take you there. My setup is midipe + Axleback, valveless (always open). There are some cold starts and a rev to 5k posted. It is louder IRL than what it seems in the video.
