Anything other than standard exhausts will be better on performance but I wouldn't think it would improve performance just by fitting the exhaust, its when you change manifolds and airfilter etc. But if your fitting an upgrade system then its best to get an upgraded manifold aswell (otherwise use a magic pipe to retain the standard manifold) if your going to buy and upgrade exhaust manifold then you will need a seperate inlet manifold, you might aswell add the air filter and needle and make it into a stage 1.
Fitting an upgrade exhaust just for the noise is a lost cause to me.

I can see how people can see fitting an exhaust for the noise is silly/waste money. Unfortunately as i have only been driving for half a year the prospect of improving performance is not affordable (insurance wise). I simply love the noise of the classic car exhaust, and the look of a single center exit.
So am i right in thinking that simply the back box with a step up or down link pipe will not improve my performance thus not raising my premium. No manifold, filter, or any other improvements.
Thanks.
