Exhaust Bypass Valves

if i heard that on the street porsche wold b the last thing i would think of.

btw man, car looks great...an way to make those tails a little more shiny?

The cars pretty dirty so thats probably why the tail lights arnt shiny. For some reason they are a dust magnet. I was thinking of getting them clear coated sometime but its not bothering me enough to get it done, lol. I think it still retains a Porsche sound at the higher RPMs like when I take off at the 1 minute mark. I think that was at 1/8th open. The first take off was half or full open.

I did that little rev when my friend walked around the car to gauge what level of opening I was at (you can tell it was pretty quiet), so I opened it to 1/8th. Thats definately my favorite setting.

@ boggtown,

Did you notice any difference good or bad in the car's power after opening up the 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.
