I am having the same issue that the OP has. Muffler hits and rattles against that rear hanger mount down in the picture. I have a hasport rear motor mount and Full Race DP/Exhaust
How would my si run with a full race downpipe and flashpro with no tune?
Is it safe to run until I get my intake, exhaust and tune in the future?
What baseball should I run with just a downpipe?
Edit: basemap not baseball lol
Thanks in advance fam!
I bought my 2012 si with 67k miles on it and i notice the rpms surge when coasting in neutral or coming to a stop in neutral. Any suggestions? Thanks in advance!
