MagnaFlow 5インチ×8インチ×14インチ オーバル ストレートスルー パフォーマンス エキゾースト マフラー 12198

The dyno-proven gain was the reason I pulled the trigger, and the straight-through design definitely woke up the mid-range. The exhaust note is deep and aggressive without being obnoxious on the highway. Fit was clean on my setup and it sounds better with every drive.

The oval shape fit perfectly into my factory hanger locations with just a little adjustment. It's deep and mellow at cruising speeds but really opens up nicely when you step on it. Only reason I'm not giving 5 stars is that the 14-inch length made it a tight squeeze under my sedan's rear bumper.

Installation was straightforward, and the muffler gives my truck a deep, aggressive tone without being obnoxious on the highway. The only thing I'd note is that it took a few days to fully break in—after that, the sound really opened up nicely.
