This Is What An E46 M3 Straight Pipe Exhaust Dump Sounds Like

A lot of people have been asking me about my exhaust setup at the track because it’s so damn loud. To be honest I never liked my exhaust really loud, but I liked the idea of having the option to get loud with a flick of a switch so I went with an electronic valve cutout system to do a full straight pipe dump with a QTP 3″ valve. Let me know what you think of both setups.

• Stock section 1 with 2 Vibrant resonators
• Status Gruppe non-resonated section 2
• QTP 3″ cutout with turndown
• Supersprint Race muffler
