Robert L. ★★★★★

Install was pretty straightforward on my 8th gen Si, and the bolt-on cat lined up perfectly with the stock midpipe. The V2 design clears everything underneath without any rattling, and the car pulls noticeably harder up top.

Timothy ★★★★★

The bolt-on catalytic converter saved me from any fabrication headaches during install, and the welds look clean and strong. My K20 feels noticeably punchier in the mid-range since swapping this on.

Sebastian G. ★★★★★

I was worried about fitment with my K24 swap, but the precision of the manifold ports was spot on. The weld quality on the bolt-on cat is clean and everything sealed up without any leaks. Definitely brought my mid-range to life.
