Just had my Magnex fitted today - same design as above. They also do the 6x4 oval tailpipe but I decided it was too much on a small car. The twin exit suits my Cup down to the ground
I already have a Green replacement panel filter and my car has covered 1600 miles from new.
My opinion :
Very good quality system, but could could be a touch better finished around the exhaust exits. The car feels more muscular - no massive gains, but feels a bit more grunty, especially in the low and mid range. Throttle response is a touch sharper too. The exhaust note is great - nice and deep with no cheap rasp to it. Its not too intrusive, but you know its there. I love the way it makes your chest vibrate between 3500 and 4000rpm when you boot it
Negatives:
It takes away the sudden kick in noise and acceleration when the motor comes on cam at 5000rpm. However, this is due to the gains lower in the rev range so you dont get that step. I was hoping for more of a howl from the exhaust note when getting towards the rev limiter, but it just stays deep and booming. Not a major problem though.
Verdict?
Great system - recommended. Now approved by Magnex for 2003 spec cars
