Mr Turbo Downpipes & secondary decat done...
Straight pipes welded in place of the secondary cats is a big no-no - it loses the 6-cylinder tone at idle, and develops an Opel fartcan exhaust drone around 1800-2500 RPM that is downright embarrassing... Though it sounds plenty angry when you get it up and going, and spits / pops on overrun, I just wouldn't have been able to live with the drone
I drove it for about 5 km, turned around and headed back to Powerflow Randburg to get two small 30cm silencers installed.
Drone is gone, idle sounds like a 6 cylinder again, and the exhaust note sounds deeper & sportier than stock, without being obtrusive.
