Anyone ever determine whether a cat back, no other mods, really makes any more power on the Z06?
If so, where in the curve? Just way up top?
I'm curious since SCCA SS class rules allow.

I believe the concensus on the more popular brands is that you can expect an 8-12 hp gain at the back with these catbax. A slight weight issue with SS vs the TI which was stock. Someone said earlier that the hp was almost incidental to the overriding desire for a different exhaust note.

BTW - as to all of this weight stuff - the DRIVER probably makes a much bigger impact than we acknowledge! Wonder during factory testing for ultimate numbers what "constant" driver weight was factored-in? 100# variation in driver weight will certainly impact 0-60 and 1/4 times when you are dealing in tenths or hundredths of a second!

So buy the catback for the sound or look and you might pick up a few ponies for good measure. :usa:
