Rear muffler.. - Recommendations?

[Pernod]

Ok, just went and saw one of my brothers friends (and one of the best mechanics in town) to get his take.

He recommended leaving the cat on the car as there is apparently talk of introducing regulations over here somtime in the medium future.

However, he said the best bang for my buck would be redo from the cat back and the introduction of a set of extractors. Anyone wish to comment on this option?

He also suggested that the best step after that would be to change the cams (and for the sake of a couple of hunderd bucks, why not!).

BTW, if your anywhere near Wellington NZ, check out total turbo up ngaronga (sp?) :wink:

If you can get Cams for a couple of hundred dollars let me know.
For some reason the 4cyl DOHC cams over here cost a fortune like
$800 a pair. I used to buy 454 Chev cams with huge lift for $240
and there is a truckload of weight/metal in them I dont know where
the justification $$$ for a set of 4cyl cams is.

Agree with the Cat back exhaust inc keeping the Cat. Others can fill
you in about their feeling on using extractors I haven't used them on
the Astina.

I'm not sure where he was going to get the cams from, but I think he said something about the jap version (which i have) has different cams to the OZ/NZ equivalent.
I sort of got lost somewhere in the conversatin over cams, but Dave has a habit of pulling off miracles when it comes to these sorts of things so i'll let you know what happens.

I'll let you know how the extractors work out ;-)

Any chance of scanning the cam profile page for the NA.
Would be good to just have the specs for comparison.

That's volume 1, I haven't got that yet but as new questions are coming to mind it won't be long.

Nah, i dont have the Manuals.

But i need to go see my engine builder to get my cam specs for the one that got reground, and i think it had the specs for the standard ones on the jobsheet.
