i agree with tooch...daalder exhausts in box hill are fantastic. they did the cat backs on mine and my friends ravs. another friend of mine is also getting his rav done there. soon i'll be getting my header and high flow cat done there as well.
btw, if anyone wants to be part of a lukey header group buy for the 3s-fe engine let me know...i'm running a group buy rite now on http://www.rav4oz.com and we need one more person!
