2007-2009 Mazdaspeed 3 Turbo Back Exhaust

One of my favorite things on a four cylinder car is exhaust, and this system freaking amazes me every time I race it. The deep sound of a four cylinder with this exhaust system sounds so good. Even passed California emissions laws with the high flow cat. Would recommend to any speed that wants a clean build that looks amazing. Quality of the part is great.

I bought and installed this full turbo back exhaust about a week and 200 miles ago. The install for the downpipe was pretty rough, I suggest soaking everything in penetrating lubricant the night before and letting the car get warm before working on it. I also installed the Corksport HPFP, which is an absolute must if you upgrade your downpipe.

The car sounds amazing now. Very deep and rumbly when I leave my neighborhood, afterfires on engine decel and it screams when you put your foot in it. The exhaust is loud, especially on startup, but the drone is minimal on the highway and does not sound "ricey" at all. When you shift at high loads, you get a nice crackle. The welds are all high quality. This is the best sounding speed exhaust I have heard (there's a chance for bias of course). amd at 900$ it's an absolute steal! The car builds boost faster and with a good tune gives you a large increase in horsepower (up to ~40 whp). If you are on the fence, pull the trigger! You won't regret it. I have and will continue to install only Corksport products, the only thing better than their quality is their customer service. Thanks for taking my money Corksport!
