MagnaFlow 5×8×18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 12468

Dropped this in on my old Mustang and the 18-inch length gives it a deep, mellow tone without any drone on the highway. Feels like it opened up the top end a bit too.

The straight-through design really wakes up the throttle response, and the oval shape fits perfectly in the stock tunnel without any rattling. It's got that deep, aggressive tone without being obnoxious on the highway, and I've put about 500 miles on it so far with zero issues.

I'm not a mechanic, so I was a bit nervous about fitment, but the oval shape cleared everything on my truck without a single modification. It's got that deep, aggressive rumble at idle that settles into a nice low hum cruising down the highway — exactly the sound I was after.
