Sound isn't the only aspect of the exhaust that has been modified. The Dinan F90 M5 exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust sports enormous, quad 4" (102mm) clamp-on, double-walled, black ceramic coated and laser engraved exhaust tips. Dinan has retained its signature straight-cut tip design, safeguarding its unique and elegant styling position amongst a crowded marketplace full of angle cuts. The tips masterfully fill up and accentuate upon the factory cut-outs showcasing an extremely aggressive, yet refined, styling that will turn heads even before it is heard.
