I have come from a go engine background, and the 2072 pipe was the best performance, i am using it with the Argus and its going great. I got some of the 0801 black pipes with the last order which i will do some back to back testing with and let you know what i find. From what i have heard the 0801 gives better run times.

We did do some comparisons with 2 identical buggies, 1 running the Argus, the other had a Massive Mods MG66, the MG66 is well know in New Zealand and Australia for being a very smooth and powerful engine, well the Argus was every bit the match for it and if our straight was longer the Argus would be ahead, not to mention the Argus is $100nz cheaper

A modded version of the Argus must be pretty impressive
