Customer Reviews
Very pleased with the product.
Awesome quality and fitment. Definitely a big notice in HP and sound.
In love with the quality of this downpipe. It is the best bang for your buck in terms of performance and sound. The install is straightforward and their video installation is all I needed for any answers.
Beautiful craftsmanship, well designed, everything bolted up perfectly. Wish it came with a little bit of instructions to help any novice installer but I guess there’s enough info online. For anyone installing this you can remove the heat shield off of the stock cat to remove it without having to remove the driveshaft as there is a lot of room to rotate the cat once it’s disconnected from the turbo. Just be aware of fiberglass dust.
Noticed an improvement in throttle response down low and turbo does seem to spool a little faster. Changed the exhaust sound a little too with the center valve pinned open. Changed the drone you can get around 2k RPM to be a little more manageable.
Love the packaging and the quality! Thought I was gonna make the car louder with the rest of my after market exhaust system but it didn’t:( I’m not sure why. With the tune we are pumping way more air and the exhaust times sound way smoother
