Large Bore HD 409 SS DPF-Back Exhaust System with Split Side Exit (49-44086-B) by aFe. This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust. Exhaust System Type: DPF-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 4". Exhaust System Sound: Moderate. Get increased exhaust flow, more horsepower and torque, improved performance and lower exhaust gas temperatures with the aFe Large Bore HD DPF-Back Exhaust System. aFe dyno tests every system for maximum gains, and constructs them from mandrel-bent stainless steel for maximum flow and long-lasting durability.

A performance exhaust system is one of the most common ways of improving a vehicle's operation. The theory is simple; just reduce restriction to increase exhaust flow and you gain power. But all exhaust systems are not created equal; in reality there's more to it than just selling some sewer pipe sized tubes.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. A typical aFe system will increase exhaust flow by up to 29% and lower EGT (Exhaust Gas Temperature) by up to 100 , with a corresponding improvement in power and performance.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The pipes of the Large Bore HD system are constructed from durable 409 stainless steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded on each side to ensure a strong attachment and the hangers also feature swaged bayonet ends to lock in place once installed. The factory mounting locations are used throughout and a 2-piece tailpipe facilitates adjustment.

Every system comes with clamps, hangers and detailed instructions to guide you through the installation. The Large Bore HD Exhaust System is made in USA.

Not bad really
Size: Large, Color: Light Grey Heather
I purchased a size Large and it's just a smidge loose but it's nothing that is really noticeable or uncomfy. I'm about 180lbs at 5'9 with somewhat of a beer belly but not a huge one lol. If you're body is about the same as mine and if you want a more fitted feel them go with a medium. So overall it's very comfortable it's my 3rd Amazon brand type of garment or clothing that ive purchased so far. Still too early to tell just how durable it is but I'll be sure to update that eventually. I use it for work (nothing heavy white collar work) and during the warm seasons I absolutely loath regular cotton style shirts. I'm not a fan of the summer weather so I tend to buy clothing that is more suitable for warm temps. This is 100% polyester and it's breathable as heck. That's what I like most about it. The overall texture and feel is somewhat "rough" but soft at the same time (if that makes any sense) but it's nothing that you'll be self conscious about. So don't let that scare you away. It's comfy and inexpensive and I recommend.

Great quality, seems to run just a little big
This is an excellent quality shirt. While I haven't put the "quick-dry" feature to the test, it definitely feels like it would dry quickly if wet. It has a little bit of weight to it but not so much that it feels heavy, just that you're well aware you're wearing it. I picked up a large and I'm about 5'9 and 175lbs (and 14 neck) - and I feel like I'm swimming in this thing (it's a bit on the bigger side). I'm definitely going to order more, probably several, but will likely drop down to a Medium and see how big a difference it makes. Hopefully it fits better without being too small. Overall, great quality and value - highly recommended (whether for golf, work, or just casual outings).
