I still have my orig exhaust although i run some light mods. For some reason my zorst has a nice deepish sound that a few folks have commented on. But i to have thought about getting an aftermarket one heres some of the ones I have contemplated bearing in mind my car is used for school runs for 2 kids and show use. I dont like noise
Manu Pro Con
Milltek Nice & widely avail Pricey & lots of warranty claims
Blueflame Good Price maybe to loud for me
Remus Very Nice Very pricey, dont know anyone with one
Apr Not sure Pricey Again Noisy I think
So with that fantastic detective work It would be Milltek but I have a hankering for the Remus, although maybe going for a pipeworkz downpipe mated to my orig silencer .
