SP Boost Activated Exhaust Cut Out in Action!!

So far we have picked up 36 RWHP and 30 ft lbs of TQ on a low boost pull! The results will be more dramatic as we turn up the boost!!

This is a 3" cutout on a APEXi exhaust with a muffler that you can see straight through.... so it flows very well. This test is on a RB30 motor with a 67mm turbo that is in a 240!!

it's QTP. and the right way to have phrased that is 'QTP also offers electronic cutouts'.
and no they don't. SP's is boost activated... QTP offers manually activated electronic cutouts.

I've been thinking about adding these to my car for a while, I can only imagine how loud it would be though
Nice job guys, I really like the fact that they aren't electronic.

heres a link to ATPs boost activated cutout. it does say they are out of stock tho, but when they do make them, they make 3" also.

QTP does infact make electronic cutouts, BUT....as I stated previously and correctly, ATP makes boost activated cutouts. so the right way for you to have phrased that....

sorry, edited.
thought you mispelled QTP since I didn't realize ATP made them. my bad.
How does the use of a cut out skew the AFR in your tune? Id imagine that with the cut out open the AFR would drop a few tenths or so compared to when the cut out is closed because the motor is able to pump the exhaust more efficiently? Would this would also allow for a few more degrees of timing?
