Hello,
I just started modding my 2015 Lexus IS AWD and I found that the Joe-z Axleback is the best sounding and most optimal option for me. Unfortunately, they have been sold out for a while and there is no ETA till they are back. So I found someone near me selling one for a pretty good price but when I went to go install it (about 2ish months after I bought it) I found that the flanges didn't match up at all. I even asked my mechanic and he confirmed that the flanges don't match up despite it being sold as just an axle-back. I did some research and found that it is sold like that with the flat face of the flange but I assume when you buy it new then it comes with an adapter or something that allows you to bolt it up correctly. I did not receive anything but the exhaust so I'm not sure, does anyone know if there is a piece or any other hardware that comes when it is bought new? If so is there any way I can buy that/those piece(s) so that I can install it? Thank you!
No adapter, just some nuts and bolts that you can pickup from a local hardware store. You could also take in your OEM bolts and find some nuts that work, I just can't exactly recall if the OEM bolts are long enough as the flange they weld on is pretty thick
Are you 100% sure cause the OEM mid-pipe and the OEM axle-back meet with these like donut gaskets. So if the OEM mid-pipe with donut style flange/gasket meets with the flat flange wouldn't it leak? and would I need to use the gasket still or just take it out? (I bought OEM hardware so the bolts and the springs)

Should be fine, I have the same setup and when I replaced the axleback portion just made sure to bolt down hard i've had to retighten the bolts as it leaked a couple times already

I believe I ran into a similar issue when I had my Invidia axleback on- I just reused the gasket on my oem midpipe, and got some stainless steel bolts, lock washers, and nuts from a hardware store. I couldn't use the OEM bolts/springs personally, because the oem bolt has a taper at the end. The bolt, lock washer and nut kept it on tight, no leaks.
