MagnaFlow 2002-2008 Lexus SC430 4.3L Street Series 觸媒後段性能排氣系統 16917

After swapping out the stock exhaust, the difference in throttle response was immediately noticeable — it pulls harder through the mid-range now. The build quality on the stainless steel tips is top-notch, too.

The exhaust note is deep and aggressive without being obnoxious on the highway, which is exactly what I wanted. I’ve had it on for three weeks and the dyno-proven performance gain is noticeable in the mid-range.

The deep tone really wakes up the driving experience on my SC430, though the 4.3L engine could use just a bit more volume for my taste. Fitment was spot-on with the cat-back design, and the perforated core keeps the note aggressive without being obnoxious on long drives.
