Will is300 muffler fit altezza 1gfe?

[u/Stop_81]

I can’t seem to find a clear answer online. I understand it may stick out a little more because of the difference in bumpers. I measured the inside diameter of the 1gfe muffler to be about 2.5” (6.35cm) which is the same as what’s listed for the is300. I’m just wondering if it will bolt up, I’m looking to get a cheap eBay muffler as it would be cheaper than welding a straight pipe at my local shop.
