I just had a new DIDO Magnaflow exhaust installed after previously having a SIDO Flowmaster. When I got my truck back I was a little dissapointed in the sound. The installer said I should change the tips and it would give it a better sound. What I was wondering is what effect does the tip have on exhaust sound. If anybody has any info that would be great. BTW I'm already scheduled for tomorrow for some 4" tips. Thanks guys.
