This Catback sounds insane!!

I was very surprised by the quality of this catback, being so adorable, I thought i would be getting a very cheap, poorly welded exhaust. The welds look like what you'd expect out of an exhaust triple the price. And same goes for the sound! I highly recommend giving flashark a chance if your looking for an exhaust!

Quad muffler burnt tip cat back exhaust

Bought the exhaust. Took awhile to get it due to being out of stock but once it was in stock they NDA it to me. Kept me in the loop about when it would be available also. Came as pictured. Was easy to install. Looks good and sounds good. Only real issue I had was they did not include the adapter to hook it up to the cat so I had to purchase it separately. Would like to see them add it to the kit but overall can't complain.

10/10 quality and sound

I was a little skeptical special compared to other catback exhaust due to price but 10/10 good tone light weight but new owners you do have to order a adapter do things right adapter it’s like 50 bucks more depending where I get it from (Overtake OEM Downpipe to 3in Cat Back Adapter) but other wise 10/10
