I have slp tiwn pipes on my 1999 XC700, and have heard to get a tempa flow to stay more consistant with jetting. Are you guys happy with this Item?? Easy to install? Safe to use?? And does it work? Am considering purchasing one. Any thing better than this? Also. Where to get one? SLP wants about $170 for it. Any better deals than this?? Thanks as always, Bob.
