Only one way to find out put it on a dyno as long as the compression is good as mentioned and cams, valves etc are good you should get slight gain as the standard exhaust is already good. it has to be to get 150bhp as standard.

Agree with the above. The only way to test the true power increase or decrease would have been to have had the car rolling roaded before the mods and then after the mods. Your best bet is to get it tuned on a RR. Now that you've changed the filter (possiblitly to get more air in) and changed the exhaust (possiblility to get more gas out) the mixture may need tweaking ever so slightly.

IMO the cone filter will have probably lost you power due to heat soak. EVERYBODY knows that the best induction on a golf 1,2,3 is panel filter and butchered airbox. I've also head instances where decat pipes can actually lose power.... (not sure if that true)

On subject of cars losing bhp over time - thats true as a general rule of thumb but if your old enough to have watched some of the earlier top gears then you will have seen the test they did with 2 mk2 16v's. One with sub 5k mileage and one with 60k on the clock - guess which one one, by a fair bit in a straight line race. :laugh:

Does that mean a high mileage Valver is quicker than a VR  :laugh:

if you do some digging on here you'll find out that a decat pipe makes no difference on a standard 16v and that the cone filter actually reduces/makes no difference to power. All your motor will do is make a sh1t load of noise!

As said above muller your box. stick some bell housing cones on the inlet and outlet run a cold air feed in a stick a k&n panel filter on it. then you'll see maybe 3-4 bhp increase.

not worth buying mods to gain a measley 1 or 2 bhp! people need to learn that if they want a fast car then a mk3 is not for them! and they should save there pennies in a little piggy and buy a better engined golf eg v6 4mo, 1.8t etc...

Sory but dont agree with this... I recently put a new piper x induction kit on my 16v and i can HONESTLY say it has defo made a difference for the better without a doubt!  :laugh:
