Just had the TSP catted downpipe installed on my 2025 type r. For the first 50 miles the car ran great. The car was running fine, and after the 4th start, leaving the store, I got the dreaded check engine light and emissions message. Car still drove pretty normal. Message on dash said to avoid...
Thanks to @garageimmi I was able to get finally a Downpipe for the car. Very simple the install great product and no issues . Comes with clear pictures instructions .
I will post clips of audio with my Mugen Group B Exhaust.
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
