just got the SU test pipe and installed it on my baby. def feel the gains, however when I put it on, it doesn't seem to snug up to the cat back part. snugs right up to the down pipe due to the donut flange, however its just straight metal on metal to the catback creating a slight leak. Any suggestions for a gasket or something???
