Yeah i also got a flanged cat and a piece of pipe made up for easy removal of the cat.

Yeah Luke I have the same.

Is this FOS? I can't believe it, can anyone prove this?

I cannot substantiate the claim that mild steel systems sound better than stainless.

Sound, noise and music are all very subjective when it comes to quality.

But an old exhaust bloke, and my dad both swear that Mild steel systems sound better. With the stainless systems sounding "tinny", possibly due to the different hardness in the different materials?

This might be based on a time period when stainless systems weren't as common, and the quality had more variance.

You are right about the "longevity" being an issue with mild steel systems used in a "city" environment. When an engine is cold, a lot of water condenses in the exhaust system. If the engine and exhaust system isn't run for long enough (eg. long drive), the water stays in the lowest point of the system, settling in the muffler.

My advice is that almost all cheap mufflers sound bad. Stick to trusted "REAL brand name" mufflers. Not sure about HKS etc.. they aren't muffler specialists.

the same reason why the ute can run the exhaust to just after the cabin. these rules still exist for new ute aswell, as a friend of mine has it on his v8 commodore ute and has never had a prob with the cops.

That's awesome ISL33P. So if I get fined, can I come see you
Might be best to check it out for sure hey?

Ive been told that i have to run a cat on my ute to get it engineered in vic but the rules might de different elsewear

why dont you just dump it after the cabin and then run a dummy exhaust the rest of the way, seen it done heaps. or you can run a bypass valve that can adjusted to open at a certain vacuum/pressure ??

you wont get fined for not running a cat on a ute, but an engineer wont clear it if it has been modified.

Just find a pre 1978 (???) ute and have no pollution gear at all. That doesnt comp;y with ADR 27A

thanks for making my point clear.
