Just noticed Zuff's post. 1000 kms. Bit more kays and I will think the power will stay but become more linear.

My AFR didn't really move with the new exhaust. I didn't take a printout but i can get it next time i'm at Silverwater.

Those are nice figures for that exhaust imho.

I'm also very curious to know if headers are going to make of break our setup.

 

That is strange. You've got a notable gain throughout whereas most of mine was at the top end and your AFR is completely different. Mine went leaner but only to the point where the lines were literally next to one another whereas yours is a fair bit richer.

 

Just for your interest my car exhibited 2 distinct performance changes.
Just like the difference between a hot dry summers day and the way it goes on a cold crisp damp night.
One about (minor) 3-4K another (major) at very close to 10K.
At the time I didn't bother to document it because I wasn't really watching the odometer but the thought crossed my mind that it probably related to miles rather than K.
There's no doubt in my mind that this occured - I've spent half my life doing seat of the pants tuning modifications to all sorts of vehicles.
I do doubt though that Nisshit would be smart enough to program these incremental adjustments into their black boxes given their inability to set suspensions up properly or even put a decent radio in the car.

Has anybody out there had experience with Injen or Borla (dual) exhaust? The exchange rate on $750US is roughly comparable with the asking price for the local HiTech stuff.

Ps: is the discount buy still on for the HiTech - and who supplies
and installs?

Me snows melting! Heat from the exhaust!

 

Well I guess I'll wait and see what happens over the next 1000km or so.

As for the Hi-tech special price I'd suggest just contacting them and asking. They can install if you want to drive down but as you probably know an exhaust isn't a difficult thing to install so it may suit you to have it shipped up and install it yourself.

The Borla has gotten some good reviews but the fact that a lot of people seem to have needed to weld it instead of using the clamps may make it inconvenient. Oh and if you haven't already don't forget to add import duties and GST to the price.
