You took the photographs with no problem at all dude! Obviously a DSLR would come up better, but that's why they cost the prices they do and there are more picture options available!
The main thing is finding what sets off a photo and you've done really well in capturing the essence of the car with some cleverly picked backgrounds!
You've also managed to use the 2 thirds rule in some of your photographs.
My only criticism would be that you should have got your stride on and removed that cone from under the bridge But that's what photoshop is for!
Depends on your definition of loud I guess, I feel sorry for your neighbours especially if you de-cat it too, that will just be too much if you live anywhere residential.

Another case of each to their own I'd say!
I wouldn't want it any louder.
I don't notice any, but that isn't to say it there isn't any! Just goes unnoticed probably!
A little boomy whilst trundlling along it can be, but yeah anything above 3.5k is just pure......
A damn fine exhaust in my eyes!
