Can anyone recommend a fix? I'm guessing new exhaust tips may fix it but I would appreciate some help before i go out spending money.
Thanks in advance
Check to see if there's a centre resonator (about half-way down the length of the car, you're looking for a long "hot-dog" style muffler). If not (and it's not uncommon for there not to be one in aftermarket exhausts), that's probably the issue, and putting one in will likely help (albeit the exhaust will be quieter over all - but there's no such thing as a free lunch).

Exhaust tips are mostly for show, they contribute very little to the sound levels or characteristics of an exhaust system

In the end, if you go to a reputable exhaust place, they'll know what to do to fix it.
