hi

just wondered what the sterling sports exhausts for ea-au are like wether theyre any good or as good as redback or lukey

whats better out a lukey, supercat, redback or sterling

Not much difference really, they are all mild steel off the shelf, and as long as the pipes are mandrel bent, there isn't a whole lot of difference... its a pipe! The big deifference will come down to what sort of mufflers you put under there, and how many of them. None of the off the shelf stuff that comes with the catback system will be as good as the specialist hi flow or glass pack mufflers money can buy.

For day to day stuff off the shelf catbacks are fine, personaly I have never heard a lukey system that sounds good to my ear, never heard a sterling or supercat. Redback is my pick, Walker's second.

One big muffler and a resonater is usually the best bet for legality/flow/note as I understand it.

have any of these systems got a rear back proper flange mount for the tail piece to center pipe ?

not the insert plus then the D clamp over to keep it tight i HATE those

The Berklee / Pex system is flanged (according to the photos - I haven't seen one for real) - and in fact from the look of the pic, the main muffler has the same proper attachment plate to take factory hanger.

Search on youtube as there's a clip of berklee system on AU - sounds very decent actually.

now that system is what you want soo so much easier to install and leak free guaranteed pretty well

Something I've discovered tho after just fitting the Berklee system is that something you don't realise is that in fact it's very likely slipjoint style coupling might make final tweaking of the tail section a tiny bit easier - ie. being able to ever so slightly twist the tail section would improve the final fit of my system (position of the outlet) - tho not enough that it really bothers me...

Also the rear muffler on that Berklee system is a straight thru perforated / louvered pipe type - offset in / centre out so it forms a slight S - but the main muffler is a capped louvered inlet and outlet type with some sort of chambering inbetween (no way of knowing if there's also baffling) - so strictly speaking it's not quite a "straight thru" type muffler as such.

The note is very deep and not obnoxiously loud even at WOT / high revs and resonance is absolutely not present anywhere in the rev range.

This true, Being able to adjust for manufacturing variance is handy.

The truth is that the slip joint never gives any trouble, but with a flanged joint it is just one more gasket to leak.

That's true enough too when you really think about it - working on machinery which is generally designed that way, I easily fall into the trap of being attracted to things on cars as well that are easy to pull apart / put together without fully appreciating the practicalities of the real situation. Being able to easily replace gaskets because it's a flanged coupling is not necessarily better than not having gaskets to fail in the first place - especially on machines like cars where the exhaust can be expected to stay fine for years - not to often shake itself to bits and crack regularly as a matter of normal course.
