Fitted the Iron Rock Offroad exhaust this morning, which arrived on Wednesday (6 day turnaround from ordering). 2.5" mandrel-bend tail pipe. I went with the Pro-Flo Hybrid muffler. And I got the Magnaflow Hi-flow cat as well. Bit of a baitch to get the old system off, and I needed a 370mm length of 2.5" pipe to make the run between the cat and the muffler (that's more due to the length of the engine pipe on the extractors fitted to my thing I figure). Lucky I did a dummy assembly Wednesday night and was able to get a length of pipe from one of the local exhaust shops yesterday morning! I also cut off and re-used the original pipe hanger from just post the original muffler.
Nice note, and my seat-of-the-pants dyno tells me there is a noticeable improvement in HP and torque (cruised much easier up one of the longer hills around here, settling into 4th earlier and able to hold it). Will probably auger well for the fuel consumption equation. In case anyone's wondering . . . $460-00 landed.
Now . . . to load up and punt over the Brindies tomorrow morning bound for Ravine, or Manjar Track, or who cares where, really.
