Sorry to jump in here but.. While you guys are on this one.. i don't like my standard exhaust system either, it's pretty crap infact, i have a new 'tyre & exhaust centre' back box but that'll fall apart again after a year as they tend to do..
Mine also has resonating waves in the exhaust at certain revs, i don't know if that's normal with these motors but to me it adds to the feeling of more crapness!
What do you go for as a good quality full replacement system without particularly wanting a performance job or any added noise.. ?
Cheers all
