borla vs magnaflow _ '03 Cobra
New borla catback for my sra swap on 03 cobra. Exhaust is stock manifolds, o/r X (unsure of brand) and GT "s type" Exhaust. 2nd part of video Exhaust is stock manifolds, o/r X, and magnaflow IRS kit. The borla is noticebly louder in person at idle and at higher rpms. The sound of the magnaflow on video actually sounds more wide open, though it was quite a bit quieter.
