Hey guys, after doing my Injen axle back i noticed the sound inside the car is excessivly loud, even compared to my friends tC with the same setup, mines twice as loud! I put dynamat all along the bottom of the trunk and still the same. Any suggestions? (besides swapping out the muffler)

 

you have a lemon?

 

does he have an intake as well?

 

maybe your bolts aren't fully tightened? or lemme ask u this, did u take anything out of the trunk? (spare tire, tool kit)

 

fully tightened, no intake, everything is in the trunk as factory supplied. Seats are up.

 

exhaust gasket?

 

brand new!
