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 or rasp. 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.

Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation for variable sound levels. Finally, our quad exit exhaust tubes exit the system into the beautiful factory RS bumper integrated exhaust tips

System Overview

The factory exhaust system starts life as a dual tube setup but then converges to a single tube before entering a suitcase style muffler. Our system uses dual 63.5mm piping with no mid mufflers or resonators, and continues all the way to our large sound absorption rear muffler. The cross sectional area of our dual setup is 26% larger than stock! There the system splits to a quad 63.5mm design. Internally the valved path is straight through with no muffling, while the unvalved path is perforated for sound level reduction. This exits the rear into the factory integrated exhaust tips.

Muffler

The muffler is responsible for tuning the exhaust note and do so without adding unnecessary restrictions to the system. This system features straight-through perforated tube that’s tightly wrapped with stainless steel and fiberglass material. The muffler has a beautiful brushed finish, and is tucked high in the exhaust tunnel, making it perfect for lowered vehicles.

Exhaust Valves

Our system features two valves that allow control of the volume of the system via the factory exhaust valve actuators. In doing so, the system can go from tame to aggressive instantly! Unlike pneumatic systems, and other common valves found in the market today, our system maintains identical OEM operation all the way down to the factory valve actuation angles. Furthermore, the system is fully compatible with exhaust remotes, allowing end users to manually open the system at the click of a button. We cast the valve housings out of T304 stainless-steel. Internally the system uses CNC-machined T303 components and brass bushings, which have stood up to our extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.

Brackets

Our brackets ensure a strong and precise fit, every time. With our design, you’ll never need to worry about the brackets sagging and losing their shape over time, or the post slipping out of the hangers. The brackets are rigid, exact in their position, fit snugly in place and are made to stand the test of time.

Tubing and Welds

We use T304 stainless steel tubing throughout. We brush and de-burr all tubes, use mandrel bending techniques to ensure the tubes keep a constant diameter throughout, and use TIG welding for a strong and attractive weld.

Clamps

Our system uses OEM-style low-profile slip clamp. Our clamp selection allows the system to sit high in the exhaust tunnel, as is favored by lowered vehicles, with ultimate compatibility no matter what midpipe you may have. Each connection point is strategically placed to ensure the system has minimal opportunity to rotate during install or during years of heavy driving. Finally, because there are no flanges or swedges on the tube, fitting the system to the factory midpipe or others is a breeze. There’s no cutting, welding, or glaring compatibility issues, and there are no gaskets to replace.

Compatibility

We’ve designed our system to be 100% bolt-on. There’s no cutting, welding, or finagling to get the system to fit. It simply bolts on for use with the factory midpipe

Safe and reliable TP for the family
Size: 24 Double Rolls (2 Ply)
This brand is the best and softest bamboo TP I have purchased. This is a staple in my house, its durable and longer lasting than other brands I have tried. Cost of this is cheaper than most others as well, bonus. Highly absorbent. Package size it suitable for the price. Also good for septic systems

Not my favorite
Size: 24 Double Rolls (2 Ply)
I've tried quite a few bamboo toilet paper brands, and this isn't a favorite. Even at 2-ply it's thin. It has a good texture while being soft, and lint free as advertised, but I find we use more of this brand due to it being thinner. It has a lower price point than some of the premium brands, but a classic case of "you get what you pay for" and since we use more it doesn't really save any money anyway. Also it says plastic free, but comes in plastic packaging - it's not clear if it is eco-plastic/ biodegradable or not. It's not a bad product, and everyone likes something different and has their own priorities, but personally I won't reorder.

Good quality and absorbancy
Size: 24 Double Rolls (2 Ply)
Was a little leery about bamboo toilet paper but I was tired of the how, even the 3 ply expensive toilet papers I've been buying, were not very absorbent. I must say I am pleasantly surprised. The sheets are smaller but they don't fall apart like the others and I think they are very absorbent even tho, at first, you don't think they will be. Will definitely buy this brand again.

High value, low price, minimal packaging, good deal
Size: 24 Double Rolls (2 Ply)
I would rather give 4.5 stars but it won't let me so 4 it is. It functions as a TP should, it is strong enough for dry and wet use. It is comfortable and pretty soft feeling. It is noticeably thinner than the other ones I have tried like amazon and gaias bamboo, though it is still fine. For 39c per 100 sheets, it is one of the few lower priced TP's that I've seen and it performs well enough that I will most likely keep buying this brand. Amazon bamboo is about the same price per sheet, but the amazon one is very rough. Honestly I'm more concerned about value here myself so my current rotation of bamboo TP will be between eco brand and amazon. I like this eco brand and I appreciate their minimal packaging. I would recommend the eco brand for the soft feel and low price per sheet. Keep in mind some may think it's a but thin. I would recommend the amazon bamboo for it's low price and strength, but it's very rough. So far these are the main two options I've seen for lower priced bamboo TP. In comparison to say costco TP, the kirkland blue wrapped standard TP is about 33c 100 sheets. The charmin ultra strong red packaged one is about 43c per 100 sheets so this eco brand bamboo TP is well priced considering the market. From what I've seen, in order to have everything a person could want in a bamboo TP, strength, softness, wet and dry performance, they cost a lot more than this one and personally I wouldn't bother if these lower priced brands work instead.
