r8 exhaust which one

[jdearden]

hi guys picked upa v8 r8 last week. a nice 28th birthday present for myself :-)
Being the big kid i am the exhaust is way too quite, sounds great at low revs but so quite at higher revs.

i want a pretty loud exhaust possible with valves so can turn down on my estate.

what are my options and prices im likely to pay.

ive also heard adding k&n air filters helps with fuel economy??


cheers for your help.
