Been thinking about getting the mountune cat-back fitted with a view to getting the rest of the upgrade as and when I can afford it. Got a couple of questions though if anyone can help:
- Would the ZS diffuser need to be altered to accomodate the system?
- How loud is it? I don't want to sound like a boy racer all the time but a nice low rev growl and high rev thunder would be good.
- Is there any performance improvement from the cat-back alone?
On another note I have recently fitted a K&N panel filter and am chuffed with it. I always felt that at low revs the car felt restricted when you put your foot down, now it goes right through the range and does it so smoothly. It has also improved my MPG, at best before i was hitting 38-40 on motorway miles, now its 45-48 and its sitting about 38 for normal city driving.
Only downside is the improvement has made me more throttle happy and i'm getting 34 for kicking the bottom out of it.
What's this I hear about a fuel crisis???
