Default First dumb-*** question

OK.

My first dumb-*** question.

Coming from a motorcycling background the first thing one usually does with any bike is replace the exhaust system with a lighter (stainless or titanium) better designed version that releases horsepower and torque and sheds a lot of unwanted weight. Match that up with the intake with free-flowing filters or a modified airbox and re-map the ECU to suit. I've never had a car in my whole life that I would have thought of doing this to but I see that there are many different companies (from small bespoke independents to big brands like Quicksilver) who sell aftermarket exhausts for the XJ series. There are also a host of Supercharger intake pipes which allege to release power and add a bit more aural character to the 'whine'.

I'm not an old age executive who bought this car to drive around in silence and absolute serenity. Neither am I a boy racer who doesn't care about being too loud and annoying the whole neighbourhood. TBO I thought this engine would be a bit louder and throatier - it does seem to be stifled somewhat in standard form.

What is the general openion of Supercharged V8 owners on this subject. Does it split opinions?

What are the accepted brand/makes of exhaust that people recommend the highest for performance/value for money?

Thanks in advance.
