   i would go for enclosed filter first then full stainless inc manifold and thats your 500 notes done with. all that i may be wrong but add say around 15/20 bhp might not sound alot for 500 notes but it is. doo one at atime to notice the power stainless manifold and zorst will give you the most bhp

   you could get a raceland enclosed with green for about 90 from kam racing and a exhaust system with the rest either a magnex or a piper

   Get a supersprint middle section it has no cat or boxes and then buy whatever backbox you want?

   The cat is in your manifold so in order to decat your car, you will need a new manifold.

    Exactly.
    Less boxes does not mean more power.
    
    Google, 'exhuast pressure pulses', and see what I mean.

    why does majority of people slam powerflow all the time??
    
    it depends where u get it made, who makes it for you, if there good, if they care to take there time and do it right!
    
    i got one made as my friend was the one making it and it was good, it was a 2" pipe from manifold to a small back box . . . loud . . . and i preferd it to my magnex system i had before, but it was too loud after time so now got magnex box on the straight through and sounds mint with manifold compared to having the magnex silencer in
    
    so basicly if you want powerflow find a good garage first!

    as previosly said u require a some sort of back pressure in ur exhaust system to remove the gases from the cylinders otherwise u will have very little power.

    if you want power dont go for a powerflow there just slung together nothing is calulated
    
    to deact you car you need a new manifold
