We had the Corsa titanium exhaust installed at the Corsa operations a few weeks ago. What a proceedure!!
First they take off the factor TI Mufflers, then they cut the pipes a few inches back of the Cats and remove them. The new system consists of an H pipe which is then connected to the muffler (round, straight thru design with tiny babbles at the front--required two patents) the next pipe angles the exhaust wider and ends in front of therear axle, the next piece goes over the axle and the 4" exhaust pice is the last piece.
At this time they are all a custom installation, they initially made 6 sets, one was the display model, the second went on the Z06 convertible for the Skunk Werkes, the third went on this car, one set was sent to a vendor and the other two are sitting on the shelf at Corsa.
The proceedure was very long because our replacement H-Pipe was a different width from the production width and a new one had to be made. They found out there was a 3/8" deviation (wider) from the Z06 cats to the standard C5 cats.
The results are fantastic...the sound at idle is slightly above normal, at low throttle it starts to snarl at you, and at WOT it howls perfermance. I ran an autocross at an airport using the runway and return roads. The seat of pants power felt awesome, and the sound of going through the gears had everyone listening. There were 8 Z06's at the event and I had the highest trap speed (92 mph) at the end of the straight.
We were trying to get to the track to see if it was measurably faster than before but it rained the night I had planned on it.
Not being a great drag racer, I have been consistently running 12.8-12.9"s. Since then the Corsa exhaust, a Donaldson, and a Ripper have been added. It should be faster, time will tell.
