I just replaced the resonator on my Borla catback (long story) with this magnaflow one I ordered. I got it welded in, and noticed it was pretty loud for some reason. After looking underneath this is what I found. I can hear/feel exhaust coming from the joint. Seems like a manufactering defect. Someone tell me if I'm wrong. Also, I've misplaced the warranty card, so my best bet would be go through the company I purchased it from correct? Thanks
