well i hear its a bitch to install but that doesnt bother me. just seeing opinions because i dont really have a day to waste changing things out, then another day changing them back if i dont like it. plus if i used it i would need the opening for the t/b opened alot. i also hear that its overkill n/a, so im open to suggestions about if it is worth the time to switch the indy with my ported stock mani.
