posted comments below on a different forum titled "Race Exhaust"
….I put these points in post about an induction kit a few weeks ago.... almost word for word this applies to the benefits of fitting an upgraded exhaust
" if you have a turbo, a well made, well fitted induction kit will work together with a remap to extract a few more horse power that 99% of the time you will never use.
if its a NA car an induction kit will rob a fair bit of vital torque, in the range of 1000 to 3500 rpm that you want every drive, and will replace it with 2 BPH at 3000 you can't possibly notice and if lucky give 7 BHP at 5000 rpm that at best you'll use for 10% of your life (if you suddenly change and like wasting petrol).
it will invalidate your insurance, make and antisocial noise, on a motorway it may drone to such an extend you will regret it and might cause issues with the way the car runs in bad weather (extreme cold and or rain)
For road use, it would be far more pleasant to drive, safer and much faster if you invested in a matching set of premium brand tyres (in the standard size), get the geometry set on all 4 wheels and work on optimising tyre pressures to get handling characteristic you like. If you have money left over an upgraded set of expensive adjustable dampers retaining the original spring rates and close to std ride height would be another idea to help you go faster
NOTE:...you will most likely unlock twice the power by doing a full service (filter, plugs oil) and running a decent synthetic brand of oil at manu spec and pumping up the tyres
sorry to be an old boring ***** but lowered springs, a loud exhaust, 19" wheels and cheap mismatching unbranded tyres rubbing on the arches is about 10 seconds a lap slower (and you need at least 15BHP gain to actually feel it on the road) "
On this engine you can get a remap for about the cost of an exhaust, it will give a bit more bottom end drivability (well worth having) a small bit in the mid range, and a noticeable bit at the top. an exhaust or and induction kit will almost certainly rob you of power everywhere you will be using it (it will sound faster but WILL be slower) those two performance extras will give you nothing aside from 5 to 10 BHP at 6000rpm full throttle work... MOST cars just need the driver to press the throttle earlier or for longer.... outside a competition environment performance parts just make it slower, nosier and cr*p
