M140i
Visited Prospeed on Monday to have the trophy fettled with, safe to say I am very impresses with the results. Went for a 2.5 bore all the way through and Charlie modified the outlet on my cat to match the rest of the exhaust to make the airflow spot on.
Charlie has changed the design of the exhaust as he is now manufacturing the whole exhaust on site so he can play around, the rear silencer is now at a 70ish degree angle and sits pretty much perfectly along with the tailpipes in the cutouts of the bumper.
Upon driving the first thing that is different is the distinct burble compared to the Janspeed, town driving and on the motorway the exhaust is quiet enought to talk over without having to raise my voice but when you plant your right foot the sound is awesome and it pulls harder all the way through the rev range.
Overall I am more than pleased with the efforts of Charlie at Prospeed, his patience and attention to detail were second to none and the price made me grin as well
Happy Days
