So you gain a bit in the low and mid and lose at the very top? Am I reading this correctly?

There is about 2-3whp loss at 6100+rpm, but over 20wtq and 15whp in the low and midrange. Check dyno graph above. Again, this was done with RPI "type" of dyno testing. The car was ran VERY hard consecutively and the loss on the top end was from the car being heat soaked. Earlier runs show even larger gains throughout the entire powerband but we dont post graphs unless its backed up consecutively.
Will you guys still have the car at the shop on Friday? If so, I'll come by and listen and if it's not too loud, I'll leave my payment.

o wow that is awesome numbers, i would sooo get on this if it was a tad cheaper. Is this install easy for shops to perform? Do the tips stick out like in the video, i have the mtech kit so it shouldnt be out as much, but do you have pics of it.

hehe. The tips look like they are out a little bit more from the top side because of how the bumper cut out is shaped but from the side, its close to stock. The larger tips make it look like they stick out more though.

holy torque batman! Here is some of the other dyno graphs. Low end and midrange are WAY up but the DME is pulling ingnition timing on the top end as its getting really hot. I have had it on the dyno for over half an hour running before doing the first pull.
Some pics of the system. Please remember that this is only a prototype and the finished version will have polished tips, mufflers, pipes.

DUUUUUDE!!!!!!!! those are some crazy numbers!!!!!!!!!!!!!!!!!!!!!!!!
I just spoke with Eloy and the dyno was taken when the car was heat soaked, resulting in a slight drop in high end power.
My car dyno'ed the exact same way but when the car was under normal conditions, the power was even all the way throughout the
power band. I'm willing to bet that the 550 exhaust will dyno much more evenly under normal conditions.
