Exhaust Bypass Valves

My low end is a little softer when open, but the top end feels stout and healthy. Ive been able to start in closed mode and hold the switch enough to open her up to 1/4 as I accelerate. That way I get a good start off the line and from then on I am above 3-4 grand so I get the extra power thats available. I put the button right on the batwing so I can hold my button and have my hand on the shifter at the same time. A short shift helps too, lol.

I used my Gtech to do a quarter mile with the valves 1/8th open. I will do a half open,full open, and completely closed tomorrow.

Heres an inside video. 1/8th open http://www.youtube.com/watch?v=_bPO868KT_M

i was just curious what your top speed in 2nd gear was and if you usually rev it out like that when the engine is still cold?

Ha, no. Definately not. That was a one time thing, The car had been warm earlier and it had just gone down. It was my only chance to get a quick video so I did. With the valves open I went to 60 in 2nd I think, it helps power at the top so I go to redline (when my gtech flashes at 6400 rpms). And I went to 90 in 3rd and then went into 4th. Or something like that. I will do some more runs later.

Boggtown--
It's been a few weeks now...whats your opinion of the mod in whole???

Well, Id say as a whole its the most bang for the buck ive gotten out of my Boxster. Everything is expensive as heck but this provided great results for about $300. Its completely reversible (sound wise), its gotten about every single car to try and race me when I pull out of anywhere lol (not trying to pull out fast, but regular driving, this ranges from big trucks, to sports cars, to muscle cars), its gotten way more people turning their heads (regularly they wouldn't notice but now they are listening for a race car and seeing me zoom by), and I haven't run into any troubles. Ive got my car back at school so I only get to drive for a little bit around the plaza on the weekends. Hopefully I will be showing up some Ferraris and AMGs, lol.
