Can someone tell me which one has better performance and which has better sound (all things being equal ie. air filter/remap). I have heard Holli's Supertrapp's on his video MPEGs but have yet to hear any clips of the V-MODs. Also, what is the name of Holli's Supertrapps? On there website I only see the 2 into1 that Kaz has on his. I think I like the ones on Hollis better.....any info would be greatly appreciated. Thanks in advance.
