2011-2021 Subaru STI / WRX Sedan Agency Power Catback Exhaust System Polished Quad Tips

Agency Power has developed one of the best sounding and performing exhaust systems for the Subaru WRX & Subaru WRX STi Sedans. The exhaust features an all T304 stainless steel piping in 3inch diameter from the catback. The piping is polished featuring robotic TIG welding. The mid-pipe includes a resonator to assist in keeping that traditional boxxer engine sound with an exotic race tone touch that does not drone in the cabin. The thick flanges offer a secure fit along with the factory placement exhaust hangers. The catback exhaust uses a high flow Y-Pipe to efficiently direct exhaust to the dual exhaust canisters. The Y-pipe features a merged collector and 3 inch piping on each extension to maximize exhaust flow. The straight through mufflers are designed to optimize horsepower with very little restriction. The catback exhaust features quad 3. 5 inch tips with the Agency Power logo. As tested on a Mustang all wheel drive dyno, the Agency Power catback exhaust made an impressive 17 all wheel horsepower and 28ft/lbs of torque. The exhausts are available for 2011-2017 Subaru WRX & 2011-2017 Subaru WRX STi Sedans.

Coat lover
Size: Large, Color: Black
This coat is warm, stylish, and very well made. The stitching is clean and the fabric feels durable. It’s perfect for layering and works great with jeans or leggings. I love that it keeps me warm without feeling bulky. Great value for the price.

Good quality

I gave this as a Christmas present and he loved it. I was worried when I ordered it that the quality might not be that good, but I worried for nothing.

This is more like a long cardigan sweater, than a coat.
Size: Small, Color: #2 Blackandwhite
This is more like a long cardigan sweater, than a coat. It doesn't have much structure & the pocket placement is too high for a coat. That being said, it's very soft & comfortable. As far as sizing goes, the sleeves run a bit long, but the coat, itself, runs a bit tight. I'm 5'10'' and a small fit me, but I wouldn't be able wear anything very thick under it & I'm thin. It's light & machine washable. I almost kept it to wear as a long sweater, but it looks like a coat ,so I sent it back. If you're very thin with long arms and don't mind the pockets being a bit high, then this could be a very stylish piece for you. Otherwise, I would pass.

i would definitely recommend. stick with your regular size or size up for a less slim fit
Size: Small, Color: Black
I usually wear a medium, I ordered a small based on reading the reviews. I am 150lbs 5’4”. this coat fits great for me personally. it’s not bulky, it’s not baggy. it is a slim fit jacket, definitely more on the slender side. when i raise my arms above my head , the sleeves do come up a bit. I would suggest sticking to your normal size or if you want a less slim fit with a tiny bit more room, sizing up wouldn’t be an issue. the coat is super soft and has some weight to it. i would recommend this jacket, it is warm and a nice piece for formal attire.
