Yeah I did that before fitting a new MAF, it did seem better. The MAF did make improvements, there were some real flat spots which are now eliminated

It just doesn't seem to boost as strong as it used to. It's had the dynachip mapping done and was a beast
 
M10 x 40 long (5-off) should do it. You will notice the performance improvement. I thought that this mod would just make the car sound as if it had more power, but it really does have more power.

The extra boominess in the cab is not to everyones liking, so hang onto that original box for a few weeks just in case. I did, but have now dumped it.
 
i am finally installing my straight through pipe and side exit exhaust today
will post some videos/pictures once installed
 
I had cat removed and centre silencer leaving just the small back box, it sounded amazing, then MOT regulations in N Ireland changed and had to put CAT back on :( which quietens it a fair bit.
 
I got my centre pipe on today, even though it was and is twisting the rear section into the chassis. But the flange on the rear is soo goosed I need the side exhaust lol!! But even with the Middle deleted it sounds bloody awesome!!! Now making me use the loud pedal much more!!
