Fabspeed Headers AR20 in Section 1 Stock Section 2 Megan Muffler
The install went flawless and had ample clearance or FCAB's and other components. Parts (flanges, nuts) were high quality. They matted with the sport cats without issue. With a dyno tune, I was able to get good gains at the top of the RPM range (>5krpm). Sound is deep on low rpms under load and slowly goes up in pitch as you climb in engine speed. It's got a nice character that's mature, but stronger than stock. I'm using a fabspeed header, sport cats, status gruppe resonated section 2 and OEM muffler.
I loved the look of them upon arrival & love the look of them installed. The sound & throttle response is terrific! I'm glad I bought them, makes me love my car even more.
