BMW 330xi Downpipe Test Fit

To make sure that every part we make fits perfectly, we always do extensive test fitting and mock ups prior to releasing a product. To start this downpipe, we went to CAD and used data that we had gathered from ultra-precise measurements to create something that would theoretically fit perfectly.

We aim to maximize the performance of our products, without jeopardizing OEM-like fitment. In the case of this downpipe, we ended up with a very large, high flowing part. Prior to making our first working mock-up, we 3D printed the piece to allow us to have a quick way to test for perfect fitment. We’re happy to say, the piece fits beautifully and we can go to production with our first design!
