Bought this filter as an extra so I'll always have one ready to use... Been using K&N filters on everything I own for many years now with NO problems at all...

Gibson Exhaust Systems Reviews


Small install problems but a really nice sound..

Reviewed By gary S (GRANBURY, TX) Reviewed for a 2016 Ford Mustang —2/4/2017 8:52 AM

I had the cat back system professionally installed. I have done my own install previously but this would have been tough in the driveway. The supports were not wielded the same distance on both pipes so one had to be moved so the tips were equal distance on each side... and the rear most hangers were too long to fit.. so they had to be trimmed... LOVE the sound, bit louder than expected but really nice low tone for an EB mustang. minimal drone on the hwy and the car seems a bit peppier!!
