Just got my dbilas inlet fitted on sunday, car feels so different, massive improvement! Thanks to Tom for the good sale. 
Just wondering what i should do to it next for more performance? So far ive got:
+ De-restricted Airbox (cold feeds / panel filter)
+ dbilas inlet manifold
+ Magnex 5x3 oval backbox
Hopefully i will get an x16xe in the future so i will be able to fit all the parts from this engine onto that.
Whats the best type of exhaust manifold to get ? 4-2-1 is more midrange isnt it ? It pulls like f**k after 5k with this inlet. Would it be worth getting better spark plugs and leads ?
Cheers,
Alex

I need to get the x16xe before i get the remap and cams though as im sure they will be different. The janspeed4-2-1 is goin for a good price on ebay, so i think ill get one of them.
The magnex de-cat's seem well priced too, will it still pass an mot with a decat ?

The protec one hangs low and bangs the floor on a low car.
The janspeed one is a good fit and well made and doesn't hit the floor.
Why don't you fit a de-cat and then put the cat on for MOT  It's easy enough.

Not much gains though. Just seemed to pick up a bit quicker on my 1.6.
