I had my Borla TD and Intense Power test pipes installed yesterday and all I can say is damn! The car is definately faster off the line as well as pulling harder through all the gears. Only downside is that I have some crappy 19" tires that won't stay on the ground in 1st gear now. sucks. I guess I'll baby it in 1st, then let her rip once in 2nd until I can get some new rubber. The exhaust seems to be vibrating against something right behind the test pipes. heat shield? Another thing, I can't believe how damn heavy the stock cats are w/ that brace attached. The shop didn't put the brace back on, but it looks like it should be find w/o it.
