59ctd Posted July 29, 2021 Share Posted July 29, 2021 What is the difference between an Invidia downpipe for a manual trans vs an automatic? 09 LGT auto here and I found a downpipe off of a 2011 WRX/STI. Invidia's website shows the same part # for 05-09 LGT manual and 08-14 WRX/STI so this should bolt up. Their website does list a diff part# for the automatic though and I am unsure what the difference is. Link to comment Share on other sites More sharing options...

awfulwaffle Posted July 29, 2021 Share Posted July 29, 2021 Looks a bit rough. Bet the cat's old. I wouldn't buy it unless it was super cheap and I didn't care whether the catalyst did anything. Link to comment Share on other sites More sharing options...
