Secondary Cat Delete & Dinan Rear Exhaust - Video & Pics

I looked at more expensive Challenge & Fabspeed X-Pipes with the secondary cat delete but decided to just remove the secondary cats on the factory mid section.

It’s amazing how such a small mod makes a huge difference in sound & power.

Sure the primary cat delete makes more power but the secondary is still restrictive. Once I drove the car I immediately noticed the car pulls harder, shits seem crisper (6 MT) and the damn thing just screams above 3K rpm’s. Still no drone with the Dinan rear section but the car is noticeably louder then before under acceleration.

Here are a few pics & video from the install.
