Matthew ★★★★★

My old cats were rattling, and this direct-fit unit went in without any modifications—the mandrel-bent tubing is a huge plus for flow, and it's been a week with no check engine light.

Julian ★★★★★

After dealing with a persistent P0420 code for months on my 2005 911, this direct-fit unit finally silenced the check engine light and the corrosion-resistant stainless shell gives me peace of mind.

Nicholas ★★★★★

The mandrel-bent tubing gave my 2004 911 a noticeable improvement in exhaust flow, and the check engine light stayed off after install. Fit perfectly with no modifications needed.
