Exhaust for the daily driver

[mad.matt]

You can also get active DB Filler Inserts from Apexi which are sprung to open under high load, if you were going down the fart cannon route.

I'm trying to find an exhaust for my 20v at the moment too, kinda like the Reinhard Double Semi Ti with the center box but don't know how loud it's gonna be.
Currently running a HKS Manifold, decat and an unknown Stainless twin box exhaust, not sure on diameter either.

Also want an that won't be restrictive for when my engine is built and will probably be going to a Martelius R1 Manifold for it too.
