Overview:

The APR Catback Exhaust System personalizes your vehicle's looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions, while our Helmholtz resonator reduces unwanted frequencies. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. A cast 3" to quad 2.5" rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation.  Finally, removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.

Size: Single, Style: 1-Way 200A Fuse, Color: Square ANL Fuse Holder
As some other reviews have said the plastic does feel a little fragile, but I've never cracked one. I have three for my 1900 watt system and they have worked excellent for my application.

I'm very happy with these I normally buy Knukonceptz they have great product and always have one of their fuses. But I needed to pinch pennies more so in decided to buy these. These are really really solid. Some said the plastic was junk but I think they must not know what they're doing bc they snapped to place properly. They are super solid my 0 gauge fit in it like a glove as should, screwed in well. And is doing its job. Would buy again for sure!
