found this on another site...very interesting thread...

I have been reading Zoom magazine no.66 over and over again and am incredibly excited by the xr6t exhaust mods featured.

For those without the magazine, Zoom's own xr6t ute went from a stock 190rwkw to 207rwkw with the only change being the removal of the centre muffler (replaced with straight pipes). Most exciting is the dyno curve which mirrors the original, looking to be simply shifted up the graph, giving useful gains throughout the rev range.

They also tested the vehicle on ADR spec sound equipment and found it to read a level which should be compliant (no garantees though).

For those XR6T owners out there I highly recommend buying this magazine and reading up on this simple mod.

I have questions about this mod for anybody who might have carried out similar mods on thier xr6t.

How much louder is the "slightly audible grumble under cruise"? Would it get annoying on a trip of 1000km or such?

How was the fuel economy affected on a general city cycle with this mod?

How was the A/F ratio affected on the dyno/road?

Cheers
