Dinan 20-25 BMW X3 M/X4 M (F97/F98) Free Flow Axleback Exhaust System - Black Tips

Perhaps equally important to the sound of the installed Dinan axle back system are the resulting aesthetics. With a nearly perfect symmetrical design, the raw muffler and pipe routing are pleasing to the eye even when the matching proportions are only partially visible after install. The piping culminates into four massive 114mm (4.5") tips that fill up the previously spacious factory cut out in the valance without appearing to be oversized and unnatural. The imposing tips utilize a new tip design with an inverted clamp neck. The new style allows for two very important things to happen. The first is the ability to have a longer tip sleeve length without sacrificing real estate for a clamp neck thus allowing larger tips even when there is limited straight pipe to clamp on to. Secondly, the interior clamp neck means that the clamp itself is almost completely hidden from view for an unblemished install. Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position amongst a crowded marketplace full of angle cuts. With systems available with either black ceramic coated or polished clamp-on, and laser engraved exhaust tips, there is a version that is sure to meet your individual aesthetic needs.
