Well, the Nismo S-tune exhaust
sounds great, but nothing to write home about in terms of gains. Picked up a nice bump down low, but other gains throughout the rest of the rev range were very minimal at best.
I think this pretty much confirms that the best bang-for-the buck gains are to be had with just the test pipes...
However, check out the gains going from just K&N filters to full exhuast (minus headers), and going bone stock to the three bolt on's!
Very, very curious to see what the headers do... if the major bottlenecks are the cats, then I'm not overly optimisitic at the moment, but we'll see...
Also still have the pod filters. Probably won't be able to make use of the OEM airboxes as I'd hoped, but will have plenty of heat shielding so should work nicely. Probalby install and dyno them either later this week or next week.
