10th gen si down pipe on 11th gen si

[FE_XI]

Yesterday on October 7 2022 I have confirmed that a 10th gen down pipe fits with no modifications this includes but not limited to
Prl cat/catless
Plm cat/catless
27won cat/catless
Those three I have 100% confirmed fit witch is leading me to believe that all fit. Hope this helps

Thanks for letting us know. I have 2 questions for you, since I put a 10th Gen downpipe on my ‘22 Si a few days ago. 1, did the spacer prevent a CEL? Also, did it fit the OEM frontpipe without issues, or did you have to pull it? I had to pull it about an inch or so but the frontpipe had a lot of give so it worked.
