Norm Butler makes a beautiful exhaust for Subies but his customer service skills not so much. He prefers to sell thru Stechnic, MMS, etc. He also does not fit the exhaust so you will likely need Stechnic or MMS anyway.

I am very happy with mine

Wasn't aware, cheers for that.

I prefer to know everything about my car. I use oil pressure gauge to guide me when I can thresh the car, and when is too hot too boost. And it tells me a lot of info such as oil grade and oil quality.

Like I said in other posts. My car used to burn 1.5l of oil per 5k. Comp test rwading is very consistent. Now with aos, it uses 200ml tops. As everyone knows, oil going into chamber will cause knocking. At least, it works on a 08sti.

Killer b header looks really good imo, shortest possible path and titanium blended alloy. Very keen to know how it would perform in real life.

how does an oil pressure gauge/AOS tell you about oil grade and quality?
unless you have an online analyser

I'm assuming the AOS you are using is a recycle design, i.e. one that goes back into the engine?
I'm not sure if you've actually solved the problem to be honest
Oil is still being blown by, you're just putting the oil back in

anyway, question by OP was exhaust, not gauges...we can start this discussion elsewhere

Sorry OP to go off topic. Hope u enjoy owning a betty.

Nice NINJA edit S20525xxx

Here's what you really said:

[QUOTE=s20525xxx;785114] Blah blah read this alfa/fiat article

Because Fiat & Alfa are so reliable, I'm going to apply their oil pressure gauge logic to my Betty.

You also failed to read the disclaimer at the bottom of the article that says:
"*Overseas customers please note that our entire website is based on US-spec cars, as sold [B]before the manufacturer left the US market[/B]: [B][U]up to 1985 (Fiat/Lancia)[/U][/B] and 1995 (Alfa Romeo)"

Haha!

Sorry PMH: last post about oil pressure - I promise!

Oil temp gauge to show heat load and an idiot light for pressure are best.

That fiat article is...well..... 2/3rds wives tales......

Tell me again how it would read for 'Worn out or diluted' oil?

I also love this pearl of wisdom "Worn Engine Bearings - (see above). A further indication can be a heavy knocking under engine load (main bearings) or a lighter knocking (connecting rod bearings)."

Awesome! so your gauge tells you visually what your ears have already told you audibly? ----->> DOk DOK DOk......lol.

no harm
i found the article funny as soon as i saw fiat/alfa
(apologies if you own either)

Im speechless......
