thanks guys.
so far, so good. the vibrant resonators reduced the in-cabin noise quite a bit. the volume level is sort of back to what it was like with the N1's small lobes. still loud, but not uncomfortably so. the low frequency rumbling exhaust note is cool. and NO raspy (magnaflow) b.s. when hitting VVL. a little more romping today after the install. the more i drive it, the more i really like the feel of these kelfords. very difficult to keep my foot out of it now and of course the mpg's suck. noticeably better acceleration in any gear at any speed.
i may be looking for a different FD for this b15 tranny, or maybe a different tranny altogether. 1st gear is about useless and it feels like i should up-shift from 5th. hmm, the p10 4.058 fd looks promising. 3k rpms @ 70mph
the dyno anticipation is killing me.
