Hey Mate

I think with the alloytec, that a 3" cat back exaust is going to be the best system for you, you could go the 2 1/2" like the ecotecs, though im sure reading somewhere that, it will decrease your performance, from a cat back exaust you might get like 2 - 3kw, though yeah, it'll sound better, though....

The alloytec is probably one of the only engines that respond really well to an exhaust mod. Some people have put 2 1/2" on and said they had good gains and little or no drone, some have put twin 2 1/4" and twin 2 1/2". From what I've supplied my self and the results my suppliers have, the 3" single is the best overall for power gain and economy, good note with no drone. $350 including shipping to NSW. It is a Manta, the same system FIT use, in fact, Manta make the systems for FIT.

man 3" exhaust is too big for the alloytec, they like to breathe but they need some back pressure, twin 2.5 X-Force exhaust or single 2.5 inch will do the job

192.9rwhp is what the single 3" gives you. Twin 2 1/2" is bigger than single 3".....

Get a stock SS dual 2 1/4" catback system (I got one for free so I only had to pay fitment) and then proceed to tell the mrs about the fuel saving benefits of a set of Pacemakers ;) I reckon you can see some noticeable gains in power, economy and sound for under $700 :thumbsup:

Shame hi-flow cats are so expensive... Does anyone know if they are really worth the dollars on a V6 with this kind of setup??
