I am running auger style inserts inside my sidepipes
The casings were custom made and the auger sits inside a perforated steel tube which is the inner for the main body of the side pipe.
Overall a 4" OD IIRC
They took a lot of bark out of the exhaust
I have followed my car from behind and cant really hear the exhaust
I have left them in for the last couple of track outings
