Hazel ★★★★★

The mandrel-bent tubing made it a perfect fit on my Audi's exhaust, and I've had zero check engine light issues since the swap. The corrosion resistance is a huge plus for winter driving, and it quieted down the exhaust note nicely.

Benjamin ★★★★★

Installation was straightforward since the direct-fit design lined up perfectly with the factory hangers. My CEL stayed off after the swap and the exhaust note is a bit deeper than stock. Feels like the engine is breathing better now.

Miles N. ★★★★★

The mandrel-bent tubing gave the exhaust a noticeably smoother flow, and the check engine light stayed off right from the first start. No check engine light issues at all so far, and the fit was spot-on for my 2005 A8.
