OK guys i thought i would post up a guide and price guide of what i have done, spent on my MPS 3 too date. please note the prices are what i spent at the time these prices may change due to Australian $, price increases prices are in AU

Cat back Exhaust- custom 3' 1st cat back $600.. rating 3/10. this was a sound mod not much gain in power but sound quicker

K/N Pannel Filter - Plastic pipes removed from front of air box. $85.. rating 2/10 not much power gain 5kw?.

Koni Yelllow shocks - Good improvement over stock good control adjustable front dampening. $900.. rating 7/10.

Mazdaspeed lowering kit - nicer ride height spring rate is 30% harder 15mm drop but its more like 20mm now when setlted.. work very well with the Koni Yellows. $500 rating 6/10 (would have got 8/10 if the were 30mm drop)

Hawk Ceramic Brakes - great improvement esp when hot. $350.. rating 8/10

CPe CAI - Great Mod! good increase in power. $bought second hand.. rating 9/10 'LOVE IT'

CPe intake pipe - this works very well with the CAI! another good mod..$310.. 8/10

BNR stage 1 turbo - love the higher power does not drop off at 5000rpm easy bolt up.. $1580.. rating 8/10 would have got a 10/10 but sometimes i wish i went with stage 2

3' Turbo back exhaust - this cost me more than it should have due to changing exhausts. Dump Pipe $600-700.. Rating 9/10, Cat back $880.. TIP, no need to take heat sheilding off bottom of dump pipe only top heat sheilds. this will save u a lot of time! total time spent (11hrs for me to do including stuff ups)

Tools used - Adjustable car stands, trolley jack, full range of sockets 8mm-22mm, 8mm-19mm long sockets, rachet, breaker bar, 5 different length extentensions, lengthening pole for use with breaker bar, different size flat screw drivers, x blade screw drivers, 8mm-22mm ring opened ended spanners, co2 sensor socket, plyers, side cutters, spring compressors. Most of all have someone with you!! extra pair of hands is very helpfull and saftey!!
