Just cut the muffler out and weld it on the stock IS

Those threads are packed with useless information.

I ran an ISF rear bumper with stock quad tips and an is350 M2 exhaust. I had to cut the tips off the exhaust and bend the muffler hangers to allow exhaust gases to flow out of the bumper quad tips. Takes all of 30mins and a torch.

If you run an ISF full catback on isx50 headers you may need to remove about 2" from the mid pipe section depending on where the isx50 headers place the mid pipe in length.

I can't say for sure as I never ran the full catback system on isx50 headers. I have a full ISF catback exhaust on ISF motor/sikky headers on the is350 chassis though. Bends and clearance under the car are the same.
